The opening of a game in draughts is not as important as in chess. In chess you need to know many
theoretical lines to be able to play at top level. In draughts one has more freedom to choose what to
play.
Still, it is necessary to have some knowledge of popular openings. It will save you a lot of time if you
know how the opening works already.
The goals of opening play are:
 Getting an interesting game
 Getting a type of game that you’re good at
 Getting a line of which you have knowledge
We aren’t interested in changing pieces, of course. Therefore we will only address the sharp lines
openings offer.
This section will give you an overview of popular openings, but there is lots more to learn about
openings. If you want to know more, you can study games yourself or visit the website of Frits Luteijn
at http://home.kpn.nl/dammen/. There is a lot of theory about openings at his site. You can try the
Google translator to read the Dutch text.

Index of openings
1.32 – 28 opening
Introduction
1) 1… 19 – 23 Symmetrical variation

1.6) System with 7.40 – 35
1.7) Groninger variation
1.8) Chizhov-exchange
How to play the opening depends on what type
of game you prefer to play. Some people like
to play classical games and their opening play
will be aimed at getting a good classical
position. Other people like modern play and
their openings will have the directive of getting
attractive modern play. And of course players
who like locking positions will play trying to get
such positions. An example will make this
more concrete.
2) 1… 18 – 23 Chefneux opening
2.1) The Fox (2.33 – 29 23 x 32 3.37 x 28 20 –

2.2) Modern variation (3… 17 – 22 x 22)
2.3) The Highlander (2.38 – 32)
Let’s assume white plays 1.34 – 29
If black wants a classical game he can choose
1…. 20 – 24 2.29 x 20 15 x 24 3.32 – 28 10 –
15.
He can also delay making classics and
something like 1… 19 – 23 2.40 – 34 14 –
3.45 – 40 10 – 14 4.32 – 28 23 x 32 5.37 x

4.4) Main line (3.37 – 32)
4.5) Surrounding variation (3.34 – 30)
Black takes <24> and the game becomes
classical. Later the game may become closed
classical.
If black wants a modern game, he can choose
1… 17 – 22 2.40 – 34 11 – 17.
If black wants a fork lock he can try 1… 20 –
25 2.40 – 34 14 – 20 3.45 – 40 10 – 14
5) 1... 18 – 22 The eagle
5.1) Mutual outpost variation (5.34 – 30 20 –
25)
5.2) The black rush (5.34 – 30 20 – 25)
5.3) Roozenburg variation (5.31 – 26 19 – 23)
5.4) Fork Lock variation (5.31 – 26 20 – 25)
The immediate 19 – 24 is here possible, but
played rarely.
4.32 – 28 17 – 21 5.31 – 26 19 – 24 6.26 x 17
11 x 22 7.28 x 17 12 x 21
6) The black panther 1... 16 – 21
6.1) Right wing lock variation (2.31 – 26 11 –
16)
6.2) Russian variation (3.38 – 32)
6.3) Dutch variation (3.37 – 32)
6.4) Andreiko variation (2... 18 – 22)
And from this position many interesting games
have been played such as Georgiev –
Sijbrands (1999), that was covered in part 2 of
this course.
There are many ways to play an opening.
Isidore Weiss once said that every opening is
good, if continued correctly…
7) The hedgehog (1... 17 – 21)
7.1) Schwarzman variation (5.38 – 32)
8) The Russian bear (1... 20 – 25)
65
An overview of popular openings
9) The cow (1... 20 – 24)
1) The cow (2.34 – 30 14 – 20)
2) Semi classical variation (2... 18 – 23)
The most frequently played move to open the
game is 1.32 – 28 which gives white the
opportunity to develop his left wing
immediately.
1.33 – 29 The diamond
1) Roozenburg opening (1... 19 – 23 2.35 – 30
20 – 25)
2) Keller opening (1... 17 – 22)
3) The hedgehog (1... 17 – 21)
4) Krajenbrink attack (1... 16 – 21)
5) Classical reply (1... 20 – 24)
6) The buffalo (1... 18 – 22 2.31 – 26 20 – 24)
The 1.32 – 28 opening
Symmetrical variation
For the same reason black’s most frequently
played answer is
1… 19 – 23 2.28 x 19 14 x 23
1.33 – 28 Sijbrands opening
White’s most simple, but sound strategy is to
change
1) Old Dutch (1... 18 – 23)
2) Modern play (1... 18 – 22)
3) The seagull (1... 17 – 21)
3.33 – 28 23 x 32 4.37 x 28
and both players can develop their positions
easily, for example:
1.34 – 29 Fork lock opening
4… 10 – 14 5.39 – 33 5 – 10
6.44 – 39 14 – 19 7.41 – 37
1) Chizhov opening (1... 19 – 23 ... 5.29 – 24)
2) Fork lock variation 1 (5.31 – 26)
3) Fork lock variation 2 (1... 20 – 25)
4) The peacock (1... 17 – 22)
1.34 – 30 French opening
1. The cheetah (1... 20 – 25 2.30 – 24)
2. Ottink variation (1... 17 – 22)
1.31 – 27 Polish opening
1) Semi-classical opening (1... 19 – 23 2.33 –
28 17 – 21)
2) Left wing opening (1 ... 17 – 21 2.27 – 31)
3) The big leap (1... 17 – 22 2.36 – 31 22 – 28)
Now black has to make up his mind what plan
to follow. If he wanted a classical game he
could have played 6… 20 – 24 already.
If black wants a quiet maneuvering game 7…
10 – 14 8.46 – 41 17 – 22 9.28 x 17 12 x 21
can be chosen.
1.31 – 26 The edge opening
1. The edge opening (1... 19 – 23)
2. The rejected edge opening (1... 17 – 21 2.26
x 17 11 x 22)
If black wants a modern play with a possible
Roozenburg-attack he can play here or at the
next move 7… 16 – 21, for example:
1.35 – 30 The wild horse
7… 16 – 21 8.31 – 26 18 – 22
9.37 – 32 11 – 16 10.46 – 41 9 – 14
11.41 – 37 3 – 9
1) The wild horse (1.35 – 30 20 – 25)
White often goes to <23> in such situations
playing 12.28 – 23 19 x 28 13.32 x 23.
66
At 12.34 – 29 black plays 20 – 24 x 24 and
later 21 – 27 x 27 getting a Roozenburg attack.
The main line
Usually 1.32 – 28 19 – 23 2.28 x 19 14 x 23 is
answered by:
3.37 – 32 10 – 14
There are several ways to play for white
depending on what his preferences are.
Things are different if white plays 9.45 – 40?!
(instead of 9.31 – 27) 14 – 20 10.30 – 24? 19 x
30 11.35 x 24 for now 25 – 30! 12.34 x 14 23 x
45 13.14 – 10 9 – 14! 14.10 x 19 22 – 28 15.32
x 23 18 x 20 wins a piece for black.
If white wants to play a sharp modern game he
can play 4.35 – 30 or 4.41 – 37 5 – 10 5.35 –
30 hoping for a Roozenburg attack after 20 –
25 33 – 29. Usually white plays
4.41 – 37 5 – 10 5.46 – 41 14 – 19
From the last diagram white usually plays
Only then he decides how to continue. He can
also play the popular 5.35 – 30 or 5.34 – 29
23 x 34 6.39 x 30.
14.38 – 33 17 – 21 15.42 – 38 21 – 26
16.41 – 36
Avoiding the king shot 16 – 21 26 – 31 13 – 19
17 x 46.
16… 11 – 17 17.48 – 42 1 – 6
Roozenburg – variation
The most popular move is 6.35 – 30 and after
20 – 25 both 7.33 – 29 and 7.40 – 35 are
played. If white wants a Roozenburg attack he
should choose 7.33 – 29, for example
If black plays 4 – 10 or 17 – 21 the normal
18.50 – 45 is fine, for example 17… 4 – 10
18.50 – 45 17 – 21 19.33 – 28 1 – 6 20.28 x 19
18 – 22 21.27 x 18 12 x 14 with a right wing
attack for white. In the second part of A Course
in draughts the game Sijbrands – Gantwarg
(1973) from this opening was shown.
7.33 – 29 10 – 14 8.40 – 35 17 – 22
9.31 – 27 22 x 31 10.36 x 27 11 – 17
11.45 – 40 6 – 11 12.30 – 24 19 x 30
13.35 x 24 14 – 20
This Roozenburg position has emerged in
many games. White doesn’t have to fear 25 –
30 for after 34 x 14 23 x 45 14 – 10 white wins.
But in this case black plays 17… 1 – 6! white
should play 18.40 – 35!
The reason is that 18.50 – 45 6 – 11 19.33 –
28 4 – 10 20.28 x 19 9 – 14 21.38 – 33 14 x
23 22.33 – 28 26 – 31 23.37 x 26 13 – 19
24.24 x 22 3 – 9 25.29 x 18 12 x 23 26.28 x
19 17 x 48 27.36 – 31 11 – 17 28.19 – 14
67
10 x 19 29.47 – 42 48 x 37 30.31 x 42 7 –
12 31.42 – 38 9 – 13 is not so pleasant for
white, he can only hope for a draw.
Of course there are many more variations, but
these sharp lines will give you an idea of what
can happen in this Roozenburg system.
Playing 22.36 – 31 10 – 14! makes things only
worse. 23.33 – 28? Is punished by 14 – 19
24.40 – 35 19 x 30 25.35 x 24 17 – 22! 26.28 x
6 23 – 28 27.32 x 23 7 – 11 28.6 x 17 12 x 41
etc. B+.
At the 8 move the Springer Contra Attack 8…
23 – 28 9.32 x 23 19 x 28 is also a popular
continuation.
th
Drost-variation
From the diagram starting the Roozenburgvariation, black can choose to play against the
Roozenburg-attack, playing the Drost gambit.
The famous Wiersma – Kuyken (1973) game
showed that also after 23.43 – 38 14 – 19
24.40 – 35 19 x 30 25.35 x 24 17 – 21 26.33 –
28 12 – 17 27.28 x 19 18 – 23 28.29 x 9 20 x
40 29.45 x 34 3 x 23 black has a good game,
since white’s left wing is locked (see game in
appendix)
6.35 – 30 20 – 25 7.33 – 29 17 – 22
Black doesn’t play 10 – 14 but keeps his piece
at <10> not going to <20> because this is
better for playing the Drost-gambit.
19.40 – 35! 6 – 11 20.33 – 28
8.40 – 35 11 – 17 9.31 – 27 22 x 31
10.36 x 27 6 – 11 11.45 – 40 17 – 21
12.38 – 33 21 – 26 13.43 – 38 11 – 17
14.30 – 24 19 x 30 15.35 x 24 17 – 21
16.41 – 37 12 – 17
If white played 50 – 45 (instead of 40 – 35)
black would be able to play 26 – 31 now.
But in this case (with 19.40 – 35! played) 20…
26 – 31 isn’t good. Black has to take the 4 – 10
temp giving white a counter-shot: 21.37 x 26
13 – 19 22.24 x 22 4 – 10 23.28 x 19 17 x 48
24.19 – 14 10 x 19 25.29 – 24 20 x 40 26.39 –
34 48 x 30 27.35 x 4 W+.
The key position can be reached with all kinds
of different move orders. Black doesn’t want to
answer 17.33 – 28 by a counter-attack at the
piece at <27>.
20… 4 – 10
21.28 x 19 9 – 14 22.36 – 31 14 x 23
17.33 – 28 7 – 12 18.28 x 19 17 – 22
The orthodox defense for white goes 19.39 –
33 22 x 31 20.36 x 27 12 – 17 21.47 – 41 2 – 7
22.44 – 39 17 – 22 23.41 – 37 22 x 31 24.26 x
27 7 – 11.
White can never play 33 – 28 because of 15 –
20 B+. This is the reason black didn’t go to
<20>!
Here or later white gives back the piece 19 –
14 10 x 30 29 – 23 18 x 29 33 x 35 =. If white
plays this immediately black is better after 1 –
6! 39 – 33 13 – 18 for white has to take care
for 26 – 31 all the time. If he plays 33 – 28
black goes 26 – 31 37 x 17 11 x 31 and the
piece at <31> can’t be changed.
White can play either 23.38 – 33 with a very
sharp game or:
23.27 – 22 18 x 36 24.29 x 9 20 x 40
25.9 – 4
In Sijbrands – Gantwarg (1990) then followed
25.4 – 27 11 – 16 26.50 – 45 3 – 9 27.27 x 4
21 – 27 28.32 x 21 16 x 27 29.45 x 34 10 14 30.4 x 31 36 x 27 31.34 – 29 8 – 13
32.39 – 34 12 – 18 33.29 – 24 17 – 22 34.44
– 39 13 – 19 with a draw.
68
Black has to do something against the 33 – 28
30 x 10 threat. He doesn’t want to play 14 – 20
or 14 – 19 because he wants to play against
white’s right wing. Playing 14 – 20 gives white
the possibility to develop his right wing playing
42 – 38 45 – 40 50 – 45 (and possibly 49 – 44
– 39) and 29 – 24 x 23 x 29, while after 14 – 19
white can change to <24> later, developing
piece 35. In the Traoré – Gantwarg (1980)
game in the appendix black showed a nice
surrounding strategy. The opening was slightly
different, black not taking the counter attack
until 9… 17 – 22 10.31 – 27 22 x 31 11.36 x 27
was played.
The sharpest defense is called the Wiersma
counter-sacrifice:
Wiersma counter sacrifice
19.40 – 35! 22 x 31 20.26 x 27 12 – 17
21.27 – 22! 18 x 27 22.29 – 23
If white keeps his piece at <19> usually it is
good for black. The idea for white is to play 39
– 33 and change back 34 – 30 24 – 20 keeping
a sound center attack.
22… 17 – 22 23.39 – 33 27 – 31
Black can also play the Springer Counter
Attack differently.
Threatening 22 – 28 21 – 27.
24.32 – 28 31 – 36
6.35 – 30 20 – 25 7.33 – 29 9 – 14
8.40 – 35 3 – 9 9.45 – 40 23 – 28
10.32 x 23 19 x 28
24… 13 – 18 25.23 x 12 8 x 17 (See Wiersma
– Georgiev (1995) in the appendix) and 24… 9
– 14 25.28 x 17 21 x 12 26.23 – 18 12 x 23
27.19 x 28 are also played.
25.28 x 17 21 x 12 26.34 – 30 25 x 34
27.24 – 20 15 x 24 28.19 x 39
The position, white having a centre attack,
black having his defensive zone intact, is about
equal.
Springer Counter Attack
From the diagram with the Roozenburg attack
black can also play
White can choose from 11.39 – 33 28 x 39
12.44 x 33, 11.38 – 33 and 11.30 – 24.
6.35 – 30 20 – 25 7.33 – 29 10 – 14
8.46 – 41 23 – 28 9.32 x 23 19 x 28
11.50 – 45? can be met by 16 – 21! 12.31 – 26
21 – 27 13.30 – 24
13.37 – 31? 28 – 33 & 17 – 21 B+1.
13.38 – 33 27 – 32 14.33 x 22 18 x 27 15.37 x
28 17 – 21 B+ 1.
13.38 – 32 27 x 38 14.43 x 23 13 – 19 gives
black an advantage.
13… 28 – 33! 14.39 x 28 14 – 19 15.43 – 39
19 x 30 16.35 x 24 27 – 31 17.36 x 27 15 – 20
18.24 x 15 25 – 30 19.34 x 25 17 – 22 20.28 x
17 12 x 23 with a better position for black.
System with 7.40 – 35
If white plays (6.35 – 30 20 – 25) 7.40 – 35 a
different kind of game evolves.
The sharp line 8… 15 – 20 9.44 – 40 20 – 24
10.50 – 44 17 – 21 11.31 – 26 21 – 27 12.32 x
21 16 x 27 13.33 – 28 23 x 32 14.37 x 28 11 –
17 15.28 – 23 19 x 28 16.30 x 19 13 x 24
17.34 – 30 25 x 34 18.40 x 20 will give an
exciting fight in which white has to play against
10.45 – 40? is too slow. Black gets an
advantage by 10… 16 – 21! 11.31 – 26 17 – 22
12.26 x 17 12 x 21
10.31 – 27 17 – 21 11.37 – 31 21 x 32
12.38 x 27 18 – 22 13.27 x 18 13 x 22
14.39 – 33 28 x 39 15.44 x 33 4 – 10!
69
black’s attacking position with outposts at <27
& 28>.
5.34 – 29 23 x 34 6.39 x 30
Chizhov popularized this continuation and got
many followers. If black wants a classical
game he can opt for 6… 20 – 24 7.30 x 19 13 x
24. Most of the times black plays
10… 10 – 14 is met by 11.34 – 29 23 x 34
12.40 x 20 25 x 34 13.39 x 30 14 x 34 and
white can choose from 14.44 – 39 winning
back te piece immediately but allowing 16 – 21
– 26, or if white doesn’t want to allow this, he
can first play 14.31 – 27?! or 15.32 – 27(!) and
then win the piece back.
6… 14 – 19 7.44 – 39 10 – 14 8.40 – 34
A more quiet approach is:
Groninger variation
This line is named after the capital city of the
Dutch province Groningen, with the same
name. In the 1970’s and 80’s draughts was
very popular and this line was explored by
strong players from Groningen.
6.32 – 28 23 x 32 7.37 x 28
After 20 – 25 white attacks 30 – 24 19 x 30 35
x 24. The most frequently played move is 8…
18 – 23 but also 17 – 22 and 16 – 21 are
popular continuations.
giving black the initiative. Now black can
consider launching a Roozenburg attack:
7 … 16 – 21 8.31 – 26 18 – 22 9.42 – 37
8… 18 – 23 9.45 – 40 12 – 18
10.46 – 41 7 – 12 11.32 – 28 23 x 32
12.37 x 28 1 – 7 13.50 – 45 17 – 22
14.28 x 17 11 x 22 15.30 – 25 16 – 21
16.31 – 26 21 – 27 17.41 – 37
17.34 – 30 can also be played like in Chizhov –
Wesselink. We show the game in the
appendix, because of the nice way in which
Chizhov plays against edge piece <36> in the
appendix.
If black plays the passive 13… 17 – 21 14.41 –
37 21 – 26 white can try to put pressure on the
opponent by building the power block, see the
Chizhov – Berçot (2002) game in the appendix.
Black has to take care not to fall victim to the
kingshot after 9… 11 – 16? 10.33 – 29 22 x 31

9… 9 – 14 10.37 – 32 11 – 16
11.41 – 37 3 – 9 12.48 – 42 7 – 11
12... 6 – 11 is also played often, but 7 – 11
turns out to be best.
White can launch the Springer Contra Attack
again playing 28 – 23 x 23, but 20 – 24 gives
black a good position. If white plays
13.34 – 29 20 – 24 14.29 x 20 15 x 24 15.40 –
34 21 – 27 16.32 x 21 16 x 27 black has got
the desired Roozenburg attack.

Most black players go to <36> playing
5.37 – 32
17… 27 – 31 18.36 x 27 22 x 31
White can attack immediately 5.29 – 24 20 x
29 6.35 x 24. This Fox is played frequently by
masters and grandmasters against weaker
opponents to complicate the game and play
against the right wing attack. Players like
Baljakin, Schwarzman and Gantwarg love to
play the Fox and have gained good results and
played several beautiful games with it.
with an exciting game. Black can also try to
maintain his right wing attack, playing 17… 19
– 23.
The opening 1.32 – 28 19 – 23 is intensively
covered in a book written by Baliakin and
Gantwarg: 1.32 – 28 19 – 23 12 systems.
The book – with English text - can be bought at
the office of the Dutch draughts federation

5… 16 – 21
The other important move is the ordinary 5… 7
– 12. White has to make a choice:
1) 6.29 – 24 19 x 30 7.35 x 24 with right wing
attack.
The second most popular answer to 1.32 – 28
is 18 – 23. Of course white can’t play 2.37 – 32
because of the Harlem shot 23 – 29 B+2. The
best replies are 2.33 – 29 and 2.38 – 32.
2) 6.39 – 33 19 – 23 7.28 x 19 14 x 23 and
form many variations we show:
8.44 – 39 10 – 14 9.50 – 44 14 – 19 10.46 – 41

The Fox
1.32 – 28 18 – 23 2.33 – 29 23 x 32
3.37 x 28
If white plays 2.34 – 29 23 x 32 3.37 x 28 black
can play 12 – 18, but after 2.33 – 29 the move
is prohibited!
Black can go in several directions depending
on his desired strategy. If black wants a
modern game, playing against a right wing
attack he can play the popular 20 – 25 entering
the Fox. This opening is called after Dutch
draughts player J.H. Vos. Since ‘vos’ means
fox in Dutch, we call this opening The Fox.
3) 6.46 – 41 1 – 7 7.41 – 37 17 – 21 8.39 – 33
21 – 26 9.43 – 39! 11 – 17
9… 19 – 23 10.28 x 19 14 x 23 11.33 – 28 is
not so attractive for black.
10.29 – 24! 19 x 30 11.35 x 24 with a good
right wing attack, in Sijbrands – Gantwarg
(1995) followed 11… 7 – 11 12.31 – 27 17 – 21
13.34 – 29 14 – 20 14.37 – 31 26 x 37 15.42 x

41 10 – 14 23.29 – 23 20 x 29 24.23 x 12 20 x
29 25.34 x 23 with a strong centre attack for
white.
3… 20 – 25 4.41 – 37 12 – 18
4… 17 – 21 can give an exciting game
especially if white allows black to create a fork
lock without piece at <15>: 5.39 – 33 15 – 20
1) 6.44 – 39 19 – 24 7.37 – 32 21 – 26 8.50 –
44 26 x 37 9.42 x 31 14 – 19 etc. wit exciting
play, see Holstvoogd – Sijbrands in the
appendix.
6.29 – 24 19 x 30 7.35 x 24
If white doesn’t want to go to <24> so early, he
can play 6.39 – 33 21 – 26 7.44 – 39 26 x 37
8.42 x 31 19 – 23 9.28 x 19 14 x 23.
2) 6.37 – 32 19 – 24 7.46 – 41 21 – 26 8.41 –
37 14 – 19 9.44 – 39 16 – 21 10.50 – 44 10 –
14 11.31 – 27 11 – 16 and in this fascinating
position 12.29 – 23! will result in an interesting
fight. A fascinating variation is: 12… 7 – 11
Eliminating the 34 – 30 x 30 change by a
kingshot.
13.34 – 29 5 – 10 14.40 – 34 12 – 17 15.27 –
22! 8 – 12 16.23 – 18! 12 x 23 17.29 x 18 and
the outpost at <18> gives shape to an
unorthodox game!
7… 11 – 16
7… 21 – 26 8.39 – 33 26 x 37 9.42 x 31 7 – 12
9… 14 – 19 can be met by 10.44 – 39 19 x 30
and instead of 11.28 – 23 18 x 29 12.33 x 35
with equality white can play 11.40 – 35 trying
to keep his attack.
10.46 – 41
71
After 10.44 – 39 17 – 21 11.46 – 41? is
punished by 13 – 19 24 x 22 21 – 27 32 x 21
11 – 17 22 x 11 6 x 46
10… 17 – 21 11.41 – 37 21 – 26 12.47 – 42
with a sound attack for white.
If black wants a right wing attack he can try 6…
9 – 13 7.41 – 37 16 – 21 8.31 – 26 21 – 27.
8.46 – 41 7 – 12 9.41 – 37 1 – 7
10.39 – 33
The sharpest move. White can play 7.41 – 37
14 – 19 8.29 – 24 20 x 29 9.33 x 13 8 x 19
10.37 – 32 10 – 14 11.32 – 27 with a semi-fork.
However black’s strong centre compensates
more than enough for this, as the G. Jansen –
Sijbrands game of 1988 proved. Sijbrands
began to build his centre activating piece 2
with 2 – 8 – 13. See the section about strategy
for this game.
7.35 – 30
In this position black has tried all kind of
continuations. We show one variations in
which white is trapped.
7… 14 – 19
7… 20 – 25 is met by 8.30 – 24! 14 – 20 and to
stop the plan 8 – 13 2 – 8 followed by an attack
at <24> white plays 9.38 – 32! a move
introduced by the author of this course. Many
opponents (also pupils of mine) have become
victim to the shot 8 – 13? 11.32 – 28! 23 x 32
12.34 – 30 25 x 23 13.41 – 37 20 x 38 14.37 x
28 W+1.
If black plays 9 – 13 the outpost is safe and
white can transfer the position to a right wing
attack or a Roozenburg attack.
10… 21 – 26 11.44 – 39
11.43 – 39 can be played trying to get the
position from Sijbrands – Gantwarg.
11… 7 – 11 12.50 – 44 17 – 21 13.31 – 27 14
– 20 14.34 – 29?! 12 – 17 15.37 – 31? 26 x 37
16.42 x 31
8.40 – 35 8 – 13 9.41 – 37
Black can now play 16 – 21, but most of the
time he goes on with 9… 6 – 11 after which
white can build the 46 / 41 / 37 tail in order to
change to <28>. If black plays 10 – 14 white
can consider to play 30 – 25 blocking black’s
left wing.
White should play 15.28 – 23 but 8 – 12 16.33
– 28 9 – 14 17.39 – 33 3 – 8 18.37 – 31 26 x
37 19.42 x 31 17 – 21 20.48 – 42 21 – 26
21.42 – 37 14 – 19 22.23 x 14 10 x 30 23.29 –
23 18 x 29 24.33 x 35 4 – 9! (threatening 1621) 25.27 – 22 * still leads to a better position
for black.
The Highlander
16… 18 – 23!! 17.28 x 19 21 – 26 and since 33
– 28 is punished by 26 x 37 32 x 41 25 – 30!
B+ white is lost.
1.32 – 28 18 – 23 2.38 – 32
is a more classical way to play for white. An
important position is reached after
After 1.32 – 28 18 – 23 2.33 – 29 23 x 32 3.37
x 28 black has more options of course.
If he wants a classical game he can play 3…
20 – 24 4.29 x 20 15 x 24.
If black wants a modern game he can play
2… 12 – 18 3.31 – 27 7 – 12
4.43 – 38 20 – 24
The Molimard-variation gets shape after 4… 17
– 21 5.37 – 31 (or 5.49 – 43) 23 – 29 6.34 x 23
18 x 29 7.33 x 24 20 x 29. More information at
Frits Luteijn’s website:

Modern variation
3… 17 – 22 4.28 x 17 11 x 22 5.39 – 33
5.41 – 37 allows 16 – 21 6.31 – 26 20 – 24
7.26 x 28 24 x 22 with an easy game for black.
5.37 – 31 14 – 20 6.49 – 43 10 – 14
5… 13 – 18 6.44 – 39 19 – 23
6… 2 – 7 would give white the extra
opportunity 27 – 22 x 22! After 6… 10 – 14
72
White’s play is severely restricted for a couple
of moves. 22.40 – 35? is punished by a
kingshot: 10 – 14 35 x 24 23 – 29 34 x 23 26 –
31 37 x 17 13 – 19 24 x 13 8 x 46 B+.
22.34 – 29 23 x 34 23.40 x 29 7 – 11
Prohibiting 33 – 28? by 26 – 31 13 – 18 B+
24.41 – 36 10 – 14 25.36 – 31 with an
interesting fight. Black wants to exploit the arc
lock while white hopes his strong centre will
give him the odds. See the Baliakin –
Mogiljanski game (1987) in the appendix.
7.27 – 22 18 x 27 8.31 x 22 would cost a piece
because of 23 – 29 24 – 30 B+1.
7.41 – 37 1 – 7 8.46 – 41 5 – 10
9.34 – 29 23 x 34 10.40 x 29 20 – 25
11.29 x 20 15 x 24
2) 14… 10 – 15 15.40 – 34 14 – 20 16.44 – 40
16 – 21 17.36 – 31 17 – 21 18.41 – 36
18.31 – 27? isn’t good because of the 12 – 17
27 x 16 26 – 31 37 x 26 19 – 23 28 x 30 17 x
46 kingshot.
Now 18… 7 – 11 or 18… 12 – 18 is played with
a complicated game that should be studied
seriously. The nice F. de Koning – Thijssen
game (2010) is shown in the appendix. GMI
Kees Thijssen is a specialist in this Highland
opening.
The most interesting move in this position that
has emerged on the board hundreds of times,
is 12.27 – 22 18 x 27 13.3 x 22 launching a
Highland attack. This opening is thus logically
called the Highland variation or Highlander.
With piece 50 at <49> this move wouldn’t be
possible because of the 19 – 23 kingshot.
Chogoliev-variation
1.32 – 28 17 – 22 2.28 x 17 11 x 22
12.27 – 22 18 x 27 13.31 x 22 16 – 21
This opening is a good choice for black players
who want an active modern game. Fascinating
games emerge after the Korchow-variation:
3.37 – 32 12 – 17?! 4.31 – 26 6 – 11 4.36 – 31
8 – 12 5.32 – 27
White is threatening to play 41 – 36 with a
strong fork lock, so black plays the logical
5… 16 – 21 6.27 x 16 22 – 28 7.33 x 22 18 x
36
Thousands of draughts lovers have played this
opening. The edge pieces make this type of
game very attractive.
Frits Luteijn’s website gives much more
information about this so-called Korchowopening:
http://home.kpn.nl/dammen/Korchow/index.htm
White can’t go 14.36 – 31? because of 24 – 29
33 x 24 19 x 30 35 x 24 13 – 19 24 x 13 9 x 36
B+1. He should go to <34> first and then play
36 – 31. Instead of 14.44 – 40 the more central
45 – 40 – 34 is also possible.
14.44 – 40
We show two important variations.
1) 14… 21 – 26 15.40 – 34 17 – 21 16.36 – 31
11 – 16 17.31 – 27 12 – 18 18.45 – 40
White can also choose 34 – 30 x 30.
18… 18 – 23 19.50 – 45 24 – 30 20.35 x 24 19
x 30 21.28 x 19 14 x 23
3.37 – 32 6 – 11 4.41 – 37 12 – 17
5.46 – 41
The alternative 5.34 – 30 7 – 12 6.30 – 25
aims at playing against an right wing or centre
attack, for example: 6… 1 – 6 7.46 – 41 19 –
23 8.35 – 30 13 – 19 9.40 – 35 9 – 13 10.45 –
40 4 – 9 11.31 – 26 2 – 7 12.50 – 45 and black
attacks playing 22 – 27, 22 – 28 or 23 – 28.
The Chizhov-attack
5… 8 – 12
73
This is the most radical move. More safe play
gives 12.34 – 29 23 x 34 13.40 x 29 or 13.39 x
30.
Both 7 – 12 and 1 – 6 are played also.
1) 5… 7 – 12 6.34 – 29
Another option is 6.31 – 27 22 x 31 7.36 x 27
and 6.32 – 28 19 – 23 7.28 x 19 14 x 23 8.34 –
29 23 x 34 9.40 x 29 10 – 14 10.35 – 30 20 –
25 11.30 – 24.
6… 19 – 23 7.40 – 34
7.31 – 27 22 x 31 8.36 x 27 23 x 34 9.39 x 30
for maneuvering play 9… 20 – 25 is met by
10.44 – 39 25 x 34 11.40 x 29!
7… 14 – 19 8.45 – 40 10 – 14 9.32 – 28 23 x
32 10.37 x 28 5 – 10 and black takes back the
centre changing 19 – 23 x 23 at the next move
or prepares this exchange with the sharp 11…
16 – 21.
12… 5 – 10 13.40 – 34 15 – 20
14.30 – 25 10 – 15 15.25 x 14 9 x 20
With a fascinating fight in which white plays
against the right wing attack.
Schwarzman maneuvering-opening
Baliakin was confronted with this opening in
the match from 1995 against Schwarzman. In
his book Schwarzmanie (Schwarzmania) he
proposed to name this continuation the
Schwarzman-opening.
2) 5… 1 – 6 6.34 – 29 19 – 23 7.40 – 34 14 –
19 8.45 – 40 8 – 12 9.32 – 28 23 x 32 10.37 x
28 20 – 24 11.29 x 20 15 x 24 12.41 – 37 16 –
21 13.31 – 26 11 – 16 with a Roozenburg
game.
1.32 – 28 17 – 22 2.28 x 17 12 x 21
The exchange is played by many strong
players who like to maneuver first before the
game gets concrete. White can respond in
many ways, the sharpest of which is
White’s most popular replies are 6.35 – 30 (20
– 25 7.32 – 28), 6.34 – 29 and our personal
favorite:
Right wing continuation
6.32 – 28 16 – 21 7.31 – 26 21 – 27
8.35 – 30 2 – 8 9.30 – 25
3.35 – 30 20 – 25 4.40 – 35
4.33 – 29 is interesting too.
Black can go to <36> changing 27 – 31 x 31
but can also maintain his attack in spite of the
weakness at <2>. This is the way Chizhov likes
to play. This opening generated many
interesting games in which white has to play
against black’s right wing attack.
4… 15 – 20 5.45 – 40 20 – 24
6.33 – 29 23 x 34 7.39 x 28
If black doesn’t want to play against the attack
via 44 – 39 followed by 30 – 24 x 24 he can
answer like Schwarzman played against
Prosman (2004):
9… 19 – 23 10.28 x 19 14 x 23
11.25 x 14 10 x 19
7… 11 – 17! 8.44 – 39 18 – 22 9.38 – 33
Black can also play even more sharp: 10… 1 –
6 11.37 – 31 and only then change 19 – 23.
Chizhov played this way several times.
Prosman played 9.49 – 44 22 x 33 10.39 x 28
and never managed to get a sound attack.
9… 14 – 20 10.50 – 45
It’s not a wrong idea to allow being locked:
10.37 – 32 20 – 24 11.31 – 27 22 x 31 12.36 x
27
10… 20 – 24
12.34 – 30
74
Many games have been played in recent years
with this system.
The main line
3.37 – 32 7 – 12 4.34 – 29 1 – 7
Black can play 4… 11 – 17 5.40 – 34 6 – 11
6.31 – 26 1 – 6 7.45 – 40 19 – 23 8.42 – 37 14
– 19 9.48 – 42 10 – 14 10.50 – 45 5 – 10 11.37
– 31 2 – 7 12.41 – 37 20 – 25 13.46 – 41 15 –
20 14.35 – 30
In M. Kroesbergen – J. Lemmen 2006 white
played a double pseudo sacrifice after which
black went terribly wrong: 11.28 – 23?! 19 x 28
12.30 x 19 13 x 24 13.31 – 27 21 x 32 14.42 –
38 6 – 11 15.38 x 18 8 – 13??
Black should play 15… 8 – 12 16.33 x 22 12 x
23 17.47 – 42 17 x 28 18.34 – 30 25 x 34
19.40 x 18 =
16.33 x 22 17 x 28 17.49 – 44! 13 x 22 18.34 –
29 24 x 33 19.37 – 32 28 x 37 20.39 x 6 and
with a piece more white won the game.
The wasp
In this well-known theoretical position black
can’t delay going to <27> any longer. 14… 10
– 15 isn’t possible because of 30 – 24 32 – 27
W+.
14… 21 – 27 15.31 x 22 17 x 28 16.33 x 22 18
x 27 17.32 x 21 16 x 27 18.29 x 18 13 x 22
It’s also possible to take 18… 12 x 23 19.37 –
32 20 – 24 20.27 x 16 24 x 35 and black holds
the centre.
19.37 – 32 11 – 17 20.32 x 21 20 – 24 21.41 –
37 24 x 35 etc.
A more quiet approach for white is:
3.31 – 26 7 – 12 4.28 x 17 12 x 21
5.37 – 31
With the intention to take back <27>. If white
plays 5.36 – 31 the smart 19 – 23 stops the
plan to take <27>.
5… 2 – 7 6.31 – 27 21 x 32 7.38 x 27
11 – 17 8.43 – 38 19 – 23 9.49 – 43
17 – 21!
5.40 – 34 19 – 23 6.45 – 40
At this moment white has no neutral move to
make the change. He should play either 36 –
31 or 34 – 30.
White can choose to play a classical game:
6.41 – 37 14 – 19 7.33 – 28 and later black will
probably change 20 – 24 x 24, for example: 21
– 26 8.39 – 33 11 – 17 9.44 – 39 20 – 24 10.29
x 20 15 x 24.
10.36 – 31 21 x 32 11.38 x 27 23 – 28
12.33 x 22 16 – 21 13.27 x 16 18 x 36
6… 14 – 19 7.42 – 37
And piece <36> guarantees an interesting
game. Chizhov won a strong game against
Schwarzman during the world championship
2003 (see appendix).
Not allowing the chain lock with 19 – 24.
7… 10 – 14 8.50 – 45 5 – 10
The Prosman-attack
Black can also go to <22> after 3.31 – 26, like
GMI Erno Prosman likes to play.
3.31 – 26 7 – 12 4.26 x 17 11 x 22
5.37 – 31 16 – 21 6.31 – 26 22 – 27
7.26 x 17 12 x 21
75
17 11 x 22 19.37 – 31 with white playing
against the right wing attack.
9.25 x 14 9 x 20 10.30 – 25 4 – 9
11.25 x 14 9 x 20 12.37 – 31 10 – 14
13.41 – 37 5 – 10 14.46 – 41 2 – 7
15.38 – 32 21 – 27 16.32 x 21 16 x 27
17.31 x 22 18 x 27 18.34 – 30 20 – 24
19.30 – 25
9.31 – 26
9.47 – 42 11 – 17 10.31 – 26 7 – 11 11.37 – 31
2 – 7 12.46 – 41 20 – 25 13.35 – 30 leads to a
position we’ve seen before…
9.47 – 42 21 – 26 10.32 – 28 23 x 32 11.37 x
28 26 x 37 12.41 x 32 19 – 23 13.28 x 19 14 x
23 can get interesting after 14.35 – 30 20 – 25
15.30 – 24.
Black has a right wing attack but a weak left
wing.
9… 21 – 27 10.32 x 21 16 x 27
9… 20 – 25 10.26 x 17 11 x 22 gives white an
easy right wing attack after 11.32 – 28 23 x 32
12.37 x 17 12 x 21 13.29 – 24 19 x 30 14.35 x
24.
The eagle
1.32 – 28 18 – 22 2.37 – 32 12 – 18
3.41 – 37
11.48 – 42 20 – 25 12.37 – 31 12 – 17
13.31 x 22 17 x 28 14.33 x 22 18 x 27
15.29 x 18 13 x 22
White can switch to another modern opening
by playing 34 – 29 here or at the next move.
7 – 12 4.46 – 41 1 – 7
Black has a right wing attack, but it is not so
strong since white can change piece <27>
easily.
White can choose from 3 popular moves:
Mutual outposts variation
Surrounding variation
1) 5.34 – 29 19 – 23 6.28 x 19 14 x 34
7.40 x 29
A recent development in this opening is
3.34 – 30 7 – 12 4.30 – 25
7.39 x 30 leads to maneuvering before the
game gets more concrete.
White wants to play against the black centre.
He could be playing against a right wing attack
later.
A variation that is frequently played
7… 10 – 14 8.35 – 30 20 – 25
9.30 – 24 14 – 20
Andreiko – Sijbrands (1969) was 9… 5 – 10
10.24 – 20? 15 x 24 11.29 x 20 10 – 15 12.45
– 40 15 x 24 13.33 – 28 22 x 33 14.38 x 20 16
– 21! 15.31 – 26 11 – 16 16.36 – 31 7 – 11
17.20 – 15
White couldn’t play 17.31 – 27 because of 4 –
10! 18.20 – 15 18 – 23! 19.15 x 4 13 – 18 20.4
x 22 17 x 28 21.26 x 17 11 x 31 22.37 x 26 28
x 46 B+.
17… 18 – 22 18.41 – 36 22 – 28 19.32 x 23 21
– 27 20.31 x 22 17 x 19 with a good game for
black, who nevertheless lost the game.
4… 11 – 17 5.31 – 26 6 – 11
6.40 – 34 1 – 6 7.45 – 40 19 – 23
8.35 – 30 14 – 19
8… 13 – 19 9.40 – 35 9 – 13 10.44 – 40 4 – 9
11.50 – 45 2 – 7 12.37 – 31 18 – 22 13.31 – 27
22 x 31 14.26 x 37 is also played after which
black continues 14… 17 – 22 like the
Schwarzman – Chizhov game (1998) in the
appendix or 14… 12 – 18 15.37 – 31 7 – 12
16.31 – 26 21 – 27 17.41 – 37 17 – 21 18.26 x
76
x 45 33 – 29 23 x 34 41 – 37 20 x 29 38 – 33
29 x 38 43 x 5. Therefore black has to play 13
th
th
– 19 x 19 at the 16 or 17 move.
After 15.39 – 34 10 – 14 16.40 – 35 14 – 19
17.38 – 32 etc. the king is caught by 23 … 21 –
27 24.41 – 37 8 – 12 25.1 x 31 13 – 18 26.31 x
13 9 x 18 =.
10.32 – 28
White can also try 10.44 – 40 5 – 10 11.50 –
44 9 – 14 12.31 – 27 22 x 31 13.36 x 27 17 –
22
13… 3 – 9 14.29 – 23! 18 x 29 15.27 – 22 17 x
28 16.32 x 34 20 x 29 17.34 x 23 gives white a
solid centre attack.
14.37 – 31 3 – 9 15.42 – 37 14 – 19 16.41 – 36
19 x 30 17.29 – 23 18 x 29 18.33 x 35 22 – 28
19.32 x 23 25 – 30 20.35 x 24 20 x 18 with an
equal position.
15… 9 – 14
16.38 – 32 27 x 38 17.43 x 32
Now <9> is opened white can play this move.
Another possibility is 16.42 – 37 27 – 32 17.38
x 27 22 x 42 18.47 x 38 3 – 9 19.41 – 37 18 –
23 20.28 x 19 14 x 34 21.39 x 30!
Preventing the problems that arise after 21.40
x 29? 10 – 14 22.44 – 40 14 – 19 23.40 – 35
19 x 30 24.35 x 24 9 – 14 25.45 – 40 4 – 10
26.49 – 44 12 – 18! (threatening 17 – 21 8 – 12
14 x 45 B+) 27.39 – 34 7 – 12 28.43 – 39 14 –
19 and after changing back white’s right wing
is ugly.
21… 25 x 34 22.40 x 29 10 – 14 23.44 – 40
White’s outpost is completely safe now, 14 –
19 is punished by 33 – 28 19 x 30 28 – 22 17 x
28 38 – 33 28 x 39 43 x 5 W+.
10… 16 – 21 11.31 – 26 11 – 16 12.37 – 32
21 – 27 13.32 x 21 16 x 27
17… 4 – 9?!
White has to watch some shots.
1) 41 – 37? 27 – 32! 38 x 27 22 x 31 36 x 27
17 – 22 28 x 17 12 x 41 47 x 36 18 – 23 29 x
18 20 x 47 B+.
2) 42 – 37? 18 – 23! 28 x 19 27 – 32 38 x 18
12 x 34 39 x 30 20 x 38 43 x 32 13 x 35 B+1.
3) 38 – 32? 27 x 38 43 x 32 17 – 21! 26 x 17
12 x 21 28 x 26 18 – 23 29 x 18 20 x 27 B+1.
17… 14 – 19 18.40 – 35 19 x 30 19.35 x 24 17
– 21 20.26 x 17 22 x 11 21.42 – 38 10 – 14
22.44 – 40 18 – 22 23.28 x 17 11 x 22 followed
by an attack at <24> has also been tried, see
Gantwarg – Wiersma in the appendix.
4 – 9 is a move introduced by former world
champion late Jannes van der Wal. After the
forced reply of white black takes a deep
kingshot, getting a king for three pieces.
14.45 – 40
18.42 – 38
44.45 – 40 isn’t wrong for after 18 – 23 white
takes 29 x 18 12 x 32 33 – 28! 20 x 29 28 x 37
8 – 12 37 – 32 winning back the piece with a
good game for white.
14… 5 – 10 15.50 – 45
After 15.39 – 34?! 9 – 14?! white can play the
surprising move 16.40 – 35! after which 14 –
19 is met by the kingshot 17.38 – 32! 19 x 39
18.43 x 34 27 x 38 19.26 – 21 17 x 26 20.28 x
17 12 x 21 21.29 – 24 20 x 40 22.50 – 45 42 x
33 23.45 x 1 and white can hide his king
behind his own pieces: 10 – 14 35 – 30 25 x 34
1x45 followed by 45 – 50.
After 15… 9 – 14 16.40 – 35 3 – 9 17.44 – 40
14 – 19? Is even worse, white can take a
kingshot with both 18.38 – 32 and 18.36 – 31!
W+, while 17… 18 – 23? 18.28 x 19 14 x 23
19.29 x 18 12 x 23 is punished by 34 – 30! 25
18… 22 – 27! 19.32 x 21 25 – 30
20.24 x 35 18 – 23 21.29 x 18 12 x 34
22.21 x 1 20 – 25 23.40 x 29 13 – 18

26.24 x 13 8 x 50
77
13 17.39 – 34 17 x 28 18.34 x 32 with an equal
position).
11.44 – 39? would give up a defender of piece
24, while black is aiming to attack the outpost
several times.
Black can get his king behind his pieces and
has the odds. See L. Thijssen – B. Terwel
(1996) in the appendix.
The black rush
11… 5 – 10
2) 5.34 – 30 20 – 25 6.30 – 24 19 x 30
7.35 x 24 14 – 20 8.33 – 29
After 11… 16 – 21 12.31 – 26 11 – 16 13.44 –
39! Is possible, with the idea of 14 – 19 14.40 –
35 19 x 30 15.35 x 24 7 – 11 16.39 – 34! 9 –
14 17.43 – 39 and 14 – 19 is met by 28 – 23!
19 x 28* 32 x 23 +/- like in Sijbrands – J. de
Jonge (blindfoldgame 1981).
White can also play 8.39 – 34 20 x 29 9.34 x
23 18 x 29 10.33 x 24 22 x 33 11.38 x 29 with
a right wing attack.
8… 22 x 33 9.39 x 28
12.47 – 42 14 – 19 13.40 – 35 19 x 30
14.35 x 24 10 – 14 15.44 – 40 14 – 19
16.40 – 35 19 x 30 17.35 x 24 9 – 14
18.45 – 40 3 – 9
The best way to defend piece 24 against the
black rush is to keep piece 50 at its spot. After
19.50 – 45? 14 – 19 20.40 – 35 19 x 30 21.35
x 24 9 – 14 22.45 – 40 14 – 19 23.40 – 35 19 x
30 24.35 x 24 4 – 9 25.49 – 44 9 – 14 26.44 –
40 14 – 19 white can’t play 32 – 27? 19 x 30
27 x 9 8 – 13 9 x 18 12 x 45, so he must allow
27.40 – 35 19 x 30 28.35 x 24 22 – 27 29.31 x
22 13 – 18 30.22 x 13 8 x 30 and white’s right
wing isn’t defended well.
9… 18 – 22
9.. 17 – 21 is another frequently played
variation. After 10.29 – 23 20 x 29 (black can
take otherwise too) 11.23 x 34 21 – 26 white
controls the centre but also a weak piece at
<41>. See the nice Gantwarg – Wirny (1983)
game in the appendix.
19.49 – 44 14 – 19 20.40 – 35 19 x 30
21.35 x 24 9 – 14 22.43 – 39 4 – 9
23.44 – 40 14 – 19 24.40 – 35 19 x 30
25.35 x 24 9 – 14 26.48 – 43!
Now 14 – 19 can be met by 32 – 27 19 x 30 27
x 9 8 – 13 9 x 18 12 x 34 37 – 32 stopping the
rush attack at white’s right wing.
Changing 26… 22 – 27 27.31 x 22 13 – 18
28.22 x 13 8 x 30 gives white control over the
centre.
10.38 – 33 10 – 14
Black can play the 13 – 18 9 – 13 22 – 27
scheme as an alternative.
3) 5.31 – 26
We have to consider two completely different
lines.
Roozenburg-variation
3.1) 5… 19 – 23 6.28 x 19 14 x 23
7.32 – 28 23 x 32 8.37 x 28
8.33 – 28 22 x 33 9.39 x 19 13 x 24 has no
point for white, since black builds the cannon
playing 10 – 14 9 – 13 5 – 10 14 – 19 10 – 14
(4 – 9).
After 5.34 – 29 23 x 34 6.40 x 29 black simply
takes a right wing attack with 22 – 27 x 27.
11.42 – 38
11.43 – 39 can also be played, but allows 22 –
27 12.31 x 22 13 – 19 13.24 x 13 9 x 38 14.48
– 42 (20 – 24 15.29 x 9 38 x 28 16.28 – 22 4 x
78
8 … 16 – 21 9.41 – 37
Black can also choose 13 – 19 (Dibmanvariation) or the Clerc – variation 21 – 27 7.31
x 22 18 x 27 8.28 x 19 13 x 24 9.32 x 21 16 x
27
7.28 x 19 14 x 23 8.31 – 27 with a right wing
lock for black.
Another plan is trying to block the Roozenburg
attack playing 9.38 – 32 11 – 16 10.41 – 37 21
– 27 11.32 x 21 16 x 27 12.37 – 31 10 – 14
12… 13 – 19? Is punished by 13.26 – 21 W+.
13.43 – 38 5 – 10 14.49 – 43 trying to attack
<27>.
Russian variation
9… 21 – 27 6.37 – 31 20 – 24
2) 2 … 11 – 16 3.38 – 32 7 – 11 4.37 – 31 19 –
23 5.28 x 19 14 x 23 6.31 – 27 23 – 28 7.32 x
23 18 x 38 8.43 x 32 with again a right wing
lock.
Black now has a sound Roozenburg attack.
Usually white is going to attack <27>
immediately playing 47 – 41 – 37 – 32.
Black can also play other kinds of systems like
3.38 – 32 18 – 22 4.43 – 38:
Fork-lock-variation
3.2) 5… 20 – 25 6.37 – 31 14 – 20
7.41 – 37 10 – 14 8.47 – 41 5 – 10
9.32 – 27 19 – 23 10.28 x 19 14 x 23
11.34 – 30 25 x 34 12.40 x 29 23 x 34
13.39 x 30 20 – 25 14.44 – 39 25 x 34
15.39 x 30 10 – 14
1) 4… 7 – 11 5.49 – 43 1 – 7 6.37 – 31 21 – 27
7.32 x 21 16 x 27 8.42 – 37 11 – 16 9.37 – 32
16 – 21 10.41 – 37 20 – 24 and black plays the
fascinating Partie Bonnard in the so-called
Valkenburg-variation.. Many games continue
11.47 – 42 13 – 18 12.28 – 23 18 x 29 13.34 x
23 18 x 28 14.32 x 23 7 – 11 15.46 – 41 14 –
19 16.23 x 14 10 x 19 with an open Bonnard.
2) 4… 13 – 18 5.49 – 43 9 – 13 6.37 – 31 21 –
27 7.32 x 21 16 x 27 8.42 – 37 19 – 23 9.28 x
19 14 x 23 with a right wing attack for black.
The opening 1.32 – 28 16 – 21 is extensively
covered in a book by L.J. Koops.
Dutch variation
2.31 – 26 18 – 22 3.37 – 32 11 – 16
4.41 – 37 7 – 11 5.34 – 29 1 – 7
6.46 – 41
From this interesting fork-lock position many
games have been played.
White can also choose to play against a right
wing attack with 6.40 – 34 13 – 18 7.45 – 40
19 – 23 8.28 x 19 14 x 23 9.46 – 41 21 – 27
10.32 x 21 16 x 27 11.29 – 24 20 x 29 12.33 x
24. A nice example is the Gerritsen – Domchev
(2010) game in the appendix.
The black panther
1.32 – 28 16 – 21
1… 16 – 21 is by far the sharpest reply to 1.32
– 28, inviting white to lock black’s right wing
playing 2.31 – 26. Sometimes black even
keeps the lock on the board deliberately to
complicate the game:
Black can now try to play a Roozenburg attack:
6… 20 – 24 7.29 x 20 15 x 24 8.40 – 34 13 –
18 9.37 – 31 21 – 27 10.32 x 21 16 x 27
Because this variation isn’t without danger
many players choose 6… 20 – 25. White can
now move either 7.29 – 23 or 7.40 – 34.
Right wing lock variation
1) 2… 11 – 16 3.37 – 32 7 – 11 4.36 – 31!
4.41 – 37 is met by 19 – 23 5.28 x 19 14 x 23
and white can’t keep the lock. Black wants to
play 21 – 27 x 27 at the next move with a
sound right wing attack.
4… 19 – 23 5.28 x 19 14 x 23 6.33 – 28!
6.31 – 27? 23 – 28 7.32 x 23 21 x 32 8.38 x 27
18 x 38 9.43 x 32 favors black.
6 ... 9 – 14
Andreiko-variation
6… 20 – 25 7.40 – 34
7.29 – 23 21 – 27 8.32 x 21 16 x 27 9.35 – 30!
25 x 34 10.39 x 30 is also interesting.
79
10.28 – 23 19 x 28 11.32 x 23 isn’t bad either,
for example: 11… 13 – 18 12.35 – 30 9 – 13
13.40 – 35 21 – 27 14.30 – 24 27 – 31 15.36 x
27 22 x 31 with an exciting play.
The hedgehog
1.32 – 28 17 – 21
Playing 2.31 – 26 11 – 17 (or 12 – 17) can lead
to the 1.32 – 28 16 – 21 opening, but black can
also choose to play 2… 19 – 23 with
maneuvering play.
2.37 – 32 21 – 26 3.32 – 27 26 x 37 4.41 x 32
delivers white a quick development of his left
wing and 4 temps.
10… 15 – 20 is punished by the kingshot 11.36
– 31! 27 x 36 12.23 – 18 12 x 32 13.38 x 18 13
x 22 14.37 – 31 36 x 27 15.30 – 24 20 x 38
16.43 x 1 +.
The main line 10… 11 – 16 11.44 – 39 7 – 11
12.30 – 24! 19 x 30 13.36 – 31 27 x 36 14.23 –
19 14 x 32 15.38 x 7 8 – 12 16.7 x 18 13 x 22
17.40 – 35 favors white.
The calm 10… 13 – 18 is the best continuation
for black leading to a centre attack after 11.37
– 31 18 x 29 12.33 x 13 8 x 19 13.41 – 37 22 x
33 14.31 x 22 17 x 28 15.38 x 29.
2.34 – 29
2.33 – 29 can be met by the sharp 20 – 25 or
2… 21 – 26 neglecting the simplifying 28 – 23
29 – 24 34 x 32 exchange.
2… 21 – 26
Dutch GMI Johan Krajenbrink likes to play 2…
11 – 17 3.40 – 34 18 – 22.
7… 14 – 20 8.45 – 40 10 – 14
9.50 – 45 4 – 10
3.40 – 34 16 – 21
Fascinating play emerges after 3… 11 – 17
4.45 – 40 6 – 11 5.37 – 32 26 x 37 6.42 x 31
19 – 23 7.28 x 19 14 x 23 8.35 – 30 20 – 25
9.41 – 37
White can’t go to <24> yet, because of 13 – 19
B+1.
9… 16 – 21 10.47 – 41 21 – 26 and black tries
to play against a right wing attack, for example
11.50 – 45 10 – 14 12.30 – 24 11 – 16 13.32 –
28 23 x 32 14.37 x 28 26 x 37 15.41 x 32 16 –
21 etc.
9… 4 – 10 is the characteristic move of the
Andreiko-variation. 9… 5 – 10 allows the
strong centre attack 28 – 23 x 23. 4 – 10 gives
black a better construction to play against this
attack. When confronted with this position in
the Sijbrands – Andreiko match of 1973
Sijbrands considered 10.29 – 23 21 – 27 11.32
x 21 16 x 27 to be too dangerous and
simplified the game playing 10.32 – 27 21 x 23
11.29 x 27 although he later won the game by
a shot.
Later 10.29 – 23 was played increasingly, with
the sharpest line being 10… 21 – 27 11.32 x
21 16 x 27 12.36 – 31?! 27 x 36 13.38 – 32
After this pseudo sacrifice white is threatening
23 – 18 34 – 30 40 x 27 so black will have to
return the piece 25 – 30 14.34 x 25 leading to
a very complicated game.
4.45 – 40 11 – 16
We look at two possible continuations for
white:
5.37 – 32 26 x 37 6.42 x 31 21 – 26 7.47 – 42
26 x 37 8.42 x 31
8.32 – 27 26 x 37 9.41 x 32 19 – 23 10.28 x 19
14 x 23 11.35 – 30 has grown more popular
recently.
8… 6 – 11
Black wants to answer 9.41 – 37 with 17 – 21!
10.31 – 26 21 – 27 11.32 x 21 18 – 23 12.29 x
18 12 x 41 White wins a lot of temps so in this
variation black will strive for a classical game.
Pieces 21 / 26 are somewhat passive.
9.50 – 45 1 – 6!
80
The Russian bear
Black still answers 16 – 21 to 10.41 – 37 and
the alternative 10.48 – 42 16 – 21 11.31 – 26
20 – 24 12.26 x 17 12 x 21 13.29 x 20 15 x 24
gives black a good classical game. White’s left
wing is weakened, so it’s hardly possible to
break open the classical structure of the game.
1.32 – 28 20 – 25 2.37 – 32
2.33 – 29 is met by 17 – 22 x 22, 17 – 22 x 21
16 – 21 or 18 – 22, all with an interesting
game.
Schwarzman-variation
2… 15 – 20 3.41 – 37 10 – 15 4.46 – 41
5.38 – 32 21 – 27
There are several other options here. For
example 4.34 – 30 25 x 34 5.39 x 30 20 – 25
6.30 – 24 (6… 44 – 39 25 x 34 7.39 x 30 15 –
20 8.44 – 39 20 – 24 gives black a good
classical game) 6… 19 x 30 7.35 x 24 leads to
a right wing attack.
Another possibility is 4.34 – 29 17 – 22 5.28 x
17 11 x 22 6.46 – 41 5 – 10 7.40 – 34 7 – 11
(or 6 – 11) 8.45 – 40 11 – 17 9.50 – 45 6 – 11
which leads to the Vermin-variation. A
theoretical line is 10.31 – 26 2 – 7 11.37 – 31
White can also play the fascinating 11.32 – 28!
19 – 23 12.28 x 19 14 x 23 13.29 – 24 20 x 29
14.33 x 24 surrounding the black centre, that is
weakened by the absence of the base piece at
<2>.
11… 19 – 23 12.32 – 27 14 – 19 13.29 – 24 20
x 29 14.33 x 24 19 x 30 15.35 x 24 23 – 28
16.38 – 33 with a sharp game.
5… 20 – 24 6.29 x 20 15 x 24 7.31 – 27 18 –
23 8.43 – 38 10 – 15 9.49 – 43 14 – 20 10.27 –
22 24 – 29 11.33 x 24 20 x 29 leads to a
mutual classical attack, with a complicated
game. This is the Bezwerzjenko-variation.
6.31 x 22 18 x 38 7.43 x 32
6.32 x 21 26 x 17 7.42 – 38 19 – 23 8.28 x 19
14 x 23 9.35 – 30 can get very interesting too.
7… 16 – 21 8.36 – 31
8.42 – 38 can also be considered, because it is
more flexible although it doesn’t stop 21 – 27 x
27. The classical reply 20 – 24 9.29 x 20 15 x
24 can be met by 10.32 – 37 followed by 37 –
31 x 32 developing the left wing nicely.
8… 6 – 11 9.42 – 38 11 – 16 10.49 – 43
4… 5 – 10
4… 17 – 21 5.31 – 26 5 – 10 is the so-called
Memel-variation.
5.31 – 27
White can also go to the edge himself: 5.31 –
26 20 – 24 6.36 – 31 15 – 20 7.41 – 36 18 – 23
8.34 – 29 23 x 34 9.39 x 30 25 x 34 10.40 x 29
13 – 18 11.29 – 23 18 x 29 12.35 – 30 24 x35
13.33 x 15 is one of the lines that is gaining
popularity recently.
Usually black tries to go to a fork-lock:
10… 20 – 25 11.47 – 42 15 – 20 12.50 – 45
White can launch a centre attack 12.29 – 24 20
x 29 13.34 x 23.
12… 10 – 15 13.31 – 27 19 – 24 14.37 – 31
Escaping from the fork-lock 14.34 – 30 25 x 23
15.28 x 30 12 – 18 gives black a more flexible
position. White’s left wing looks offbeat with the
undeveloped
piece
at
<46>.
14… 26 x 37 15.42 x 31 and black has to
decide whether he wants to eliminate 34 – 30
by playing 13 – 19?! or play more quietly with
either 15… 5 – 10 or 15… 21 – 26.
5… 19 – 23 6.28 x 19 14 x 23
The idea to occupy <25> & <23>
simultaneously was introduced by former world
champion Andris Andreiko. Black’s centre is
strong enough to allow this 23 / 25 bond.
7.33 – 28 9 – 14 8.28 x 19 14 x 23
9.39 – 33
After 9.38 – 33 10 – 14 10.33 – 28 black can’t
play neither 14 – 19? nor 13 – 19? and thus
81
has to change again with 10… 4 – 10 11.28 x
19 14 x 23 which indeed is played, but
because in this variation the black position is
weakened, more popular has become 9.38 –
33 13 – 19 10.33 – 28 17 – 22 11.28 x 17 11 x
31 12.36 x 27 10 – 14 and black keeps the
initiative.
position that has occurred many times already.
22.38 – 33? is now punished by 16 – 21 23.27
x 7 23 – 29! 24.33 x 24 19 x 30 25.35 x 24 20 x
29 26.34 x 23 18 x 29 27.7 x 18 13 x 35 B+1.
The alternative 22.39 – 33 23 – 29! favors
black, especially after 23.34 x 23 18 x 29 24.33
x 24 19 x 30! 25.35 x 24 20 x 29 for example
26.27 – 22 14 – 19 27.43 – 39 16 – 21! and
28.31 – 27 is met by 11 – 17 25 – 30 – 34 19 –
23 13 x 44 B+.
9… 10 – 14 10.44 – 39 13 – 19
15… 12 – 17 16.42 – 38 17 – 22
17.28 x 17 11 x 22 18.47 – 42 7 – 12
19.33 – 28 22 x 3 3 20.39 x 28 2 – 8
21.44 – 39
11.49 – 44
This is a modern continuation. The most
popular way to continue used to be 11.50 – 44
11… 17 – 21
21.43 – 39? 20 – 24 22.49 – 43 24 – 29! favors
black.
21.44 – 39 can’t be met by 16 – 21? 23.27 x 16
6 – 11 24.16 x 7 23 – 29 25.34 x 23 18 x 29
26.7 x 18 13 x 44 because of 27.40 – 34 29 x
40 28.45 x 34 44 – 50 29.49 – 44 50 x 30
30.35 x 2 W+
11… 4 – 9? 12.27 – 21! gives white a kingshot
to <4>.
12.36 – 31
White has all kind of alternatives here. World
champion juniors 2011 Roel Boomstra
introduced 12.33 – 28 21 – 26 13.39 – 33 8 –
13 14.35 – 30?! followed by 4 – 9 15.34 – 29
23 x 34 16.30 x 39. White holds the centre and
can later launch a Highland-attack.
22… 6 – 11 23.39 – 33 23 – 29 24.34 x 23
After 24.33 x 24 19 x 39 25.43 x 34 14 – 19
26.49 – 43 19 – 24 only 27.28 – 22 is left for
white. 28.27 – 22 18 x 27 29.31 x 22 loses a
piece by 24 – 29 & 25 – 30 B+1 and 28.43 –
39 loses to 16 – 21 27 x 7 24 – 30 35 x 24 20 x
29 34 x 23 18 x 29 7 x 18 13 x 35 B+1.
12… 21 – 26 13.41 – 36 8 – 13
14.33 – 28 4 – 9
14… 2 – 8 wouldn’t allow 15.39 – 33? because
of the 16 – 21 18 – 22 23 – 29 kingshot.
However black rather allows 39 – 33? as this is
worse than 38 – 33 which gives a better
distribution of pieces.
24… 18 x 29 25.33 x 24 19 x 30 26.35 x 24 20
x 29 with about equal play. This position is also
possible with 49 at <47>, as we saw, but now
white’s distribution of pieces is better.
15.38 – 33
11… 17 – 21
15.39 – 33 2 – 8 16.44 – 39 12 – 17 17.49 – 44
17 – 22 18.28 x 17 11 x 22 19.33 – 28 22 x 33
20.39 x 28 7 – 12 21.44 – 39 6 – 11 leads to a
11… 8 – 13 would allow the 27 – 22 34 – 30
exchange although this isn’t attractive for white
either, so play continues 12.33 – 28 2 – 8
82
13.39 – 33 4 – 9 14.44 – 39 and black should
choose between 17 – 21 and 17 – 22.
12.36 – 31 21 – 26 13.33 – 28 8 – 13
14.39 – 33 2 – 8 15.47 – 41
This move, an idea introduced by Harm
Wiersma, looks strange at first sight, because
it creates a dangling piece at <41>. The point
is however that black now can’t play 12 – 17
due to 34 – 30 40 x 29 27 – 21 32 x 23, so he
must play 20 – 24 or 23 – 29 with a
complicated game, in which white’s control
over the centre should compensate the
weakness at <41>.
6.47 – 42
White can play the Molimard-exchange to
<22> immediately, like in Clerc – Chizhov Wch
2001 (see appendix).
6… 12 – 18 7.28 – 22 17 x 28
9.33 x 22 18 x 27 10.31 x 22 8 – 12
11.32 – 27 2 – 8 12.37 – 31 12 – 18
13.31 – 26 7 – 12 14.27 – 21 16 x 27
15.22 x 31
White wants to play against black’s left wing,
surrounding the centre.
Semi-classical variation
15… 23 – 29
2) 2… 18 – 23 3.30 – 25 23 x 32
4.37 x 28 13 – 18 5.41 – 37 17 – 21
15… 20 – 24 16.34 – 29 23 x 34 17.40 x 20 15
x 24 18.44 – 39 favors white.
This variation can be played if black wants to
surround the white centre. It is similar to 1.31 –
27 19 – 23 2.33 – 28 17 – 21 3.28 x 19 14 x 23
4.38 – 33 (with reversed colors).
16.34 x 23 18 x 29 17.33 x 24 20 x 29
18.44 – 39 14 – 20 19.50 – 44
with a complicated game.
1.32 – 28 20 – 24 2.37 – 32 18 – 23 is often
played, but no clear theoretical lines have
appeared yet.
The cow
1.32 – 28 20 – 24 2.34 – 30
1.33 – 29 The diamond
This opening gives black two interesting
possibilities:
Roozenburg-opening
1) 2… 14 – 20 3.30 – 25 10 – 14
4.37 – 32 18 – 23 5.42 – 37
1.33 – 29 19 – 23 2.25 – 30 20 – 25
2… 14 – 19 can be met by 3.30 – 24 3.30 – 25
or 3.40 – 35.
After 3.30 – 25 the most active move is 3… 17
– 22 4.25 x 14 9 x 20.
The alternative 3… 10 – 14 4.39 – 33 17 – 22
5.44 – 39 11 – 17 6.32 – 28 23 x 32 7.37 x 28
4 – 10 8.29 – 23! 18 x 29 9.34 x 23 gives the
odds to white.
Now 5… 17 – 21 can be met by 6.31 – 26
(which is not possible after the normal 5.41 –
37) 5… 12 – 18 is met by 6.39 – 34! Therefore
black usually plays:
5… 4 – 10
83
3.40 – 35 10 – 14 4.30 – 25 20 – 24 5.29 x 20
15 x 24 6.34 – 30 5 – 10 7.45 – 40 17 – 21
8.39 – 34 and if black goes to <26> white will
change 32 – 28 x 32 and build the power block
to put pressure at <24>.
1) 13.31 – 26 27 – 32 14.38 x 27 22 x 42 15.47
x 38 and black should try to surround white’s
attack.
2) 12.47 – 41 1 – 6 13.37 – 32 11 – 16 14.32 x
21 17 x 37 15.41 x 32 9 – 14 16.28 x 17 12 x
21 17.33 – 28 7 – 12 and black plays against
the right wing attack again.
3.40 – 35 14 – 20
3… 14 – 19 4.30 – 24 19 x 30 5.35 x 24 9 – 14
5… 10 – 14 6.24 – 19 13 x 33 7.39 x 10 5 x 14
8.38 – 33 favors white.
6.45 – 40 14 – 20 7.50 – 45 3 – 9 8.38 – 33 10
– 14 9.33 – 28 5 – 10 10.28 x 19 14 x 23 11.43
– 38 17 – 22 12.31 – 27 22 x 31 13.36 x 27
leads to a Roozenburg attack.
3) 12.46 – 41 1 – 6 13.48 – 42 9 – 14 14.31 –
26
White has to take care: after 14.28 – 23? 5 –
10!! he has no good move left! 15.37 – 31 is
punished by 27 – 32! 16.38 x 27 22 – 28 17.23
x 32 13 – 19 18.24 x 22 17 x 46 B+. Check
yourself how to punish the other possible white
moves.
14… 27 – 31 15.36 x 27 22 x 31 16.37 – 32 31
– 36 with an interesting game.
4.44 – 40 10 – 14 5.38 – 33 14 – 19
6.30 – 24 19 x 30 7.35 x 24 17 – 22
8.42 – 38 11 – 17 9.32 – 28 23 x 32
10.37 x 28
The Keller-opening
White takes a right wing attack. After 9.50 – 44
6 – 11 10.47 – 42 5 – 10 black doesn’t have to
fear the attack at <23>, because 11.33 – 28 23
x 32 12.38 x 18 9 – 14 13.38 – 33 14 x 23
14.33 – 28? gives black the elegant kingshot
14… 17 – 22!! 15.28 x 6 23 – 28 16.32 x 23 12
– 17 17.23 x 21 16 x 27 18.31 x 22 13 – 18
19.22 x 13 8 x 50 + as was performed in
Tsinman – Kalmakov 2000 and Skliarow – De
Voogd 2004.
1.33 – 29 17 – 22 2.39 – 33 11 – 17
3.44 – 39 6 – 11 4.50 – 44 1 – 6
5.31 – 26 16 – 21 6.32 – 28 19 – 23
7.28 x 19 14 x 23
These moves lead to the fascinating Kelleropening. The amount of theory of this opening
is huge. I wrote a series of articles on this
opening in draughts magazine Hoofdlijn
(consisting of 37 articles in total!). You can also
find theory about this opening at the Luteijn
website. Frits Luteijn has played many games
in this system and is known to be a
connoisseur on the Keller-opening (and many
other openings).
10… 16 – 21 11.41 – 37
11.38 – 32? fails due to 21 – 27 12.32 x 21 17
x 37 13.41 x 32 6 – 11! 14.28 x 6 18 – 23
15.29 x 18 20 x 27 B+1.
11… 21 – 27 12.50 – 44 6 – 11
The Hedgehog
1.33 – 29 17 – 21
This opening moves can lead to the same
variations as after 1.32 – 28 17 – 21 2.33 – 29
or 2.34 – 29, but white can also try the modern
system 2.39 – 33 21 – 26 3.44 – 39 11 – 17
4.50 – 44 6 – 11 5.34 – 30.
Krajenbrink-attack
1.33 – 29 16 – 21 2.31 – 26 11 – 16
In this position with mutual outposts white
holds the centre and can choose from:
These moves usually lead to a sharp game.
We show what is called the Krajenbrink-attack:
84
3.37 – 31
2… 13 x 22 has been played many times by
former world champion Chogoliev. White can
try to get a fork-lock playing 3.31 – 26 12 – 18
4.36 – 31 7 – 12 5.32 – 27 1 – 7 6.38 – 33 9 –
13 7.42 – 38 19 – 23 8.41 – 36 as happened in
Sijbrands – Chogoliev 1990.
Another main line is 3.39 – 33 7 – 11 4.44 – 39
1 – 7 5.50 – 44 and black can play 5… 18 –
22, 5… 20 – 25 or 5… 19 – 23 all with a
complex game.
3… 6 – 11 4.31 – 27 18 – 22 5.27 x 18
13 x 22 6.41 – 37 9 – 13
3.34 – 30 7 – 12 4.30 – 25 13 – 18
Black has to correct his division of pieces and
reinforce the right wing. White must choose
either the scheme 5.39 – 33 6.44 – 39 7.40 –
34 or 5.40 – 34 6.34 – 30 7.45 – 40 and if
white decides to play against a future black
attack the games gets exciting.
The buffalo
1.33 – 29 18 – 22 2.31 – 26 20 – 24
3.29 x 20 15 x 24
Black can also choose 2… 19 – 24 3.39 – 33
22 – 27 4.32 x 21 16 x 27 5.37 – 32 11 – 16
6.32 x 21 16 x 27 7.41 – 37 17 – 22 8.44 – 39

8… 14 – 19 9.50 – 44 6 – 11 10.46 – 41 1 – 6
11.38 – 32 27 x 38 12.43 x 32 but 2… 20 – 24
x 24 is much more interesting!
7.39 – 33
Sijbrands introduced the Springer Contra
Attaque in this position, playing 7.29 – 23 19 x
28 8.32 x 23.
After 7.39 – 33 black can play either 7… 21 –
27 8.32 x 21 16 x 27 or 7… 13 – 18 8.44 – 39
19 – 23, see the Gantwarg – Sijbrands (1988)
game in the appendix.
4.34 – 30
Other moves aren’t serious. 4.37 – 31 allows
24 – 29 34 x 23 19 x 28 32 x 23 22 – 27 31 x
22 17 x 19 and 4.38 – 33 22 – 28! Is no
problem for black either.
The classical reply
1.33 – 29 20 – 24 2.29 x 20 15 x 24
3.32 – 28 17 – 21 leads to a classical game.
More interesting is 3.32 – 28 16 – 21 4.31 – 26
4.39 – 33 21 – 26 is also played.
4… 21 – 27 5.38 – 33
5.37 – 31 18 – 23 leads to a centre attack for
black
5… 27 – 32 6.28 – 22 17 x 28 7.33 x 22 18 x
27 8.37 x 28 11 – 17 9.39 – 33 13 – 18 10.44 –
39 18 – 22 like Mathijssen – Dolfing (2002).
3.34 – 30 is also popular, for example 18 – 23
4.39 – 33
White can also choose 4.30 – 25 12 – 18 5.40
– 34 7 – 12 6.34 – 30 1 – 7 7.45 – 40
4… 12 – 18 5.32 – 28 23 x 32 6.37 x 28 18 –
23 7.42 – 37 23 x 32 8.37 x 28 13 – 18 etc.
Black has two continuations, both leading to
interesting types of play.
4… 13 – 18
4… 22 – 28 5.32 x 23 19 x 28 6.30 x 19 14 x
23 gives black a centre attack and a
fascinating game may lie ahead.
1.33 – 29 18 – 23 2.29 x 18 12 x 23
85
5.36 – 31 18 – 23 6.32 – 27 12 – 18
7.37 – 32 7 – 12 8.41 – 37 8 – 13
If black delays the 19 – 23 x 23 3exchange
even more with 3.31 – 26 7 – 12 4.37 – 31 1 –
7 5.42 – 38 20 – 25 6.41 – 37 14 – 20 7.46 –
41 10 – 14 8.47 – 42 5 – 10 9.32 – 27 etc. we
arrive at the same fork-lock position as from
the 1.32 – 28 18 – 22 opening (line 3.2).
Usually white doesn’t occupy <36> yet, not
finishing his fork-lock, so black gets an extra
option playing 22 – 28 sometime, white trying
to surround black’s centre attack.
3… 7 – 12
1.33 – 28 Sijbrands-opening
3… 19 – 23 4.28 x 19 14 x 34 5.40 x 29 7 – 12
is also a good idea for black, leading to the
same opening as 1.32 – 28 18 – 23 2.33 – 29
23 x 32 3.37 x 28 17 – 22 4.28 x 17 11 x 22
5.39 – 33 13 – 18 with exchanged colors.
1.33 – 28 is the favorite openings move of the
famous Ton Sijbrands.
Old Dutch
1.33 – 28 18 – 23
4.40 – 34 1 – 7 5.45 – 40 19 – 23
The Old Dutch opening usually leads to a
classical game and possibly a Highland attack.
An example play would be something along
these lines: 2.39 – 33 12 – 18 3.44 – 39 7 – 12
4.31 – 27 20 – 24 5.37 – 31 14 – 20 6.41 – 37
White can launch the Highland-attack already
playing 27 – 22 x 22 and black could reply with
the symmetrical exchange 24 – 29 x 29.
6… 10 – 14 7.34 – 29 23 x 34 8.40 x 29 20 –
25 9.29 x 20 15 x 24 10.27 – 22 18 x 27 11.31
x 22 and we arrive at positions to those that
arose from the 1.32 – 28 18 – 23 lines.
5… 20 – 25 6.42 – 38 15 – 20 7.50 – 45 10 –
15
Another popular line is 7… 19 – 23 8.28 x 19
14 x 23 9.32 – 28 23 x 32 10.37 x 28 20 – 24
11.29 x 20 25 x 14 etc.
8.31 – 26
Modern play
1.33 – 28 18 – 22
Usually this opening leads to a modern game:
2.38 – 33 12 – 18 3.42 – 38 7 – 12 4.47 – 42 1
– 7 5.34 – 29 20 – 25 6.39 – 34 19 – 23 7.28 x
19 14 x 23 8.32 – 28 23 x 32 9.37 x 28 etc.
The sharpest move here is 8… 16 – 21.
8… 5 – 10 is usually met by 9.36 – 31 but the
aggressive 9.28 – 23 19 x 28 10.32 x 23 can
also be played.
9.37 – 31 11 – 16 10.31 – 27 10.41 – 37?
White should play 10.31 – 27 22 x 31 11.26x37
5 – 10 12.29 – 24 etc. taking a right wing
attack.
10… 7 – 11 11.46 – 41 4 – 10! 12.47 – 42 2 –
7 leads to a difficult situation for white. The
special move 4 – 10 is played to meet the 29 –
24 attack. If black played 5 – 10 he would not
be able to attack the outpost since the 14 – 19
attack at the outpost would then be punished
by the 31 – 27 29 – 24 27 – 22 32 x 5 kingshot.
If white indeed takes the attack the game can
continue with 13.29 – 24 20 x 29 14.34 x 23 18
x 29 15.33 x 24 22 x 33 16.38 x 29 19 x 30
17.35 x 24 14 – 19 18.40 – 35 19 x 30 19.35 x
The alternative 2.31 – 27 22 x 33 3.39 x 28 19
– 23 4.28 x 19 14 x 23 is not attractive for
white, since his left wing is not developed well,
while piece <27> is blocking this development.
2.38 – 33 12 – 18 3.34 – 29
Another possibility is 3.31 – 26. Black then has
also several options. The exchange 19 – 23
4.28 x 19 14 x 23 again gives white choice
between 32 – 28 x 28 and 34 – 29 x 29.
3.31 – 26 7 – 12 4.37 – 31 19 – 23 5.28 x 19
14 x 23 6.32 – 27 leads to the so-called
Wiersma-opening, black can play either 6… 13
– 19 or the sharp 6… 23 – 28.
86
2… 14 – 19 3.45 – 40
24 10 – 14 20.44 – 40 14 – 19 21.40 – 35 19
x 30 22.35 x 24 5 – 10 and white has huge
problems defending his outpost (see C. Pippel
– Mathijssen game in appendix).
3.33 – 28 is an interesting variation leading to
modern play. A critical line is 3…17 – 22 4.28 x
17 11 x 22 5.39 – 33 10 – 14 6.43 – 39 12 – 17
7.48 – 43 6 – 11 8.45 – 40 5 – 10 9.32 – 28 23
x 32 10.37 x 28 8 – 12 11.41 – 37 16 – 21
12.31 – 26 20 – 24 13.29 x 20 15 x 24 14.46 –
41 21 – 27 with a Roozenburg attack for black.
6.28 x 19 14 x 23 7.32 – 28 23 x 32
8.37 x 28 16 – 21 9.43 – 38
with a modern game. Black can try to get a
Roozenburg attack.
Another popular line in this opening is
5… 7 – 11 6.43 – 39 10 – 14 7.48 – 43 5 –
10 8.45 – 40 1 – 7 9.32 – 28
The seagull
1.33 – 28 17 – 21 2.39 – 33
After 9.31 – 26 black should take care not to
fall victim to the shot 9… 12 – 17? 10.26 – 21!
17 x 26* 11.32 – 28 23 x 32 12.37 x 17 11 x 22
13.29 – 24 20 x 29 14.34 x 1 W+.
If white wants to avoid complications 2.31 – 26
20 – 24 3.26 x 17 11 x 33 4.38 x 20 15 x 24
can be played.
2… 21 – 26 3.44 – 39 11 – 17 4.50 – 44
9… 23 x 32 10.37 x 17 11 x 22 11.41 – 37 16 –
21 12.31 – 26 21 – 27 13.37 – 31 with an
interesting game.
Black has now several possibilities. Let’s
consider two of them:
3… 10 – 14 4.50 – 45
1) 4… 6 – 11 5.31 – 27 19 – 23
5… 1 – 6? can be strongly met by 6.28 – 23 19
x 28 7.32 x 23 18 x 29 8.34 x 23 with centre
attack.
5… 17 – 21 6.27 – 22 18 x 27 7.28 – 23 19 x
28 8.33 x 31 is not very exciting…
6.28 x 19 14 x 23 7.33 – 28 9 – 14 8.28 x 19
14 x 23 9.38 – 33 10 – 14 10.34 – 30. White
will try to surround the black centre. White will
not play 33 – 28 but he will try to get control
over <29> later.
4.32 – 28 23 x 32 5.37 x 28 is a frequently
played alternative.
4… 5 – 10
Chizov-opening
Tenfold world champion Alexeï Chizhov likes
to play 5.29 – 24 20 x 29 6.33 x 24 19 x 30
7.34 x 25, for example: 13 – 19 8.38 – 33 8 –
13 9.42 – 38 15 – 20 10.39 – 34 2 – 8 11.44 –
39 10 – 15 12.47 – 42 White trying to get
pressure at black’s left wing. At 12… 20 24 he
plays 13.34 – 29 23 x 34 14.40 x 20 15 x 24
15.45 – 40 18 – 23 16.32 – 28 23 x 32 17.37 x
28 12 – 18 18.40 – 34 etc. At 12… 17 – 21 he
can play 13.34 – 29 23 x 34 14.39 x 30 etc.
2) 4… 7 – 11 5.31 – 27
If white doesn’t want to play this line, he can
choose 5.33 – 29 20 – 24 6.29 x 20 15 x 24
7.38 – 33 10 – 15 8.42 – 38 etc.
6 … 17 – 22 7.28 x 17 11 x 31 8.36 x 27 19 –
23 9.35 – 30
White now can’t successfully surround black’s
centre, because black’s left wing is too strong.
He would better try to get a Roozenburg attack
after 20 – 25 10.33 – 29 etc.
Fork-lock-variation 1
5.31 – 26 20 – 25 6.37 – 31 14 – 20
7.41 – 37 10 – 14
1.34 – 29 Fork-lock-opening
The solid 7.20 – 24 8.29 x 20 25 x 14 has been
played many times, but we follow a more
interesting line.
1.34 – 29 19 – 23 2.40 – 34
After 2.33 – 28 23 x 34 both 3.40 x 29 and 3.39
x 30 are played. After 3.39 x 30 white will
correct the distribution of pieces quickly again
by playing 38 – 33 42 – 38 47 – 42 etc.
8.46 – 41 5 – 10 9.32 – 28 23 x 32
10.37 x 28 19 – 23 11.28 x 19 13 x 24
87
The peacock
Black has fork-locked the opponent. From this
popular theoretical position the main line is:
12.41 – 37 8 – 13 13.37 – 32 2 – 8 14.42 – 37
14 – 19
1.34 – 29 17 – 22 2.40 – 34 11 – 17
3.45 – 40 6 – 11 4.50 – 45 1 – 6 5.31 – 26 16 –
21 leads to the Keller-opening, but white can
also play:
3.32 – 28 6 – 11 4.37 – 32 19 – 23
5.28 x 19 14 x 23 6.41 – 37 10 – 14
If black wants to eliminate the 7.35 – 30 move
he can play 6… 13 – 19, for example 7.46 – 41
10 – 14 8.45 – 40 5 – 10 9.32 – 28 23 x 32
10.37 x 28 16 – 21 11.31 – 26 19 – 23 12.28 x
19 14 x 23 etc.
15.48 – 42
7.35 – 30 20 – 25 8.45 – 40 5 – 10
After 15.47 – 41 17 – 22 white should not play
16.48 – 42 10 – 14 17.32 – 28 because of 12 –
17! with tactical problems for white, for 18.37 –
32 is punished by 18 – 23! 19.29 x 27 24 – 29
20.33 x 24 20 x 29 21.34 x 23 17 – 22 22.27 x
18 13 x 33 23.39 x 28 16 – 21 24.26 x 17 11 x
33 25.38 x 29 19 x 50 B+, but 16.32 – 28 10 –
14 17.28 x 17 12 x 21 18.26 x 17 11 x 22 19.38
– 32 8 – 12 20.33 – 28 22 x 33 21.29 x 38 like
in Dibman – Stokkel (1983) (see appendix).
9.40 – 35 would allow 23 – 28 32 x 23 22 – 27
31 x 22 17 x 19 and white’s right wing will be
locked. Therefore white should make sure he
still has the 30 – 24 29 – 23 33 x 35 exchange
if black takes the 23 – 28 22 – 27 exchange.
9.46 – 41 14 – 19
At 9… 1 – 6 white plays 10.50 – 45.
10.40 – 35
15… 10 – 14 16.31 – 27 17 – 21
17.26 x 17 11 x 31 18.37 x 26
with an interesting fight in the fork-lock.
Fork-lock-variation 2
1.34 – 29 20 – 25 2.40 – 34 14 – 20
3.45 – 40 10 – 14
Black can take the fork-lock at once, if he
wishes, playing 3… 19 – 24.
Black has to choose between playing 10 – 14
and 9 – 14 & 3 – 9. 10… 10 – 14 can be met
by 11.32 – 28 23 x 12.37 x 28 16 – 21 with an
interesting, modern game. The alternative is
11.44 – 40 14 – 20 12.50 – 45 20 – 24
Black can’t take a centre attack playing 12…
22 – 28? 13.33 x 22 17 x 28 because of the
shot 14.29 – 24! 20 x 29 15.30 – 24 29 x 20
16.34 – 30 25 x 34 17.40 x 29 23 x 34 18.32 x
25 W+1.
13.29 x 20 15 x 24 and white can simply play
14.34 – 29 23 x 34 15.40 x 20 25 x 14 16.31 –
4.32 – 28
From here there also often will emerge a forklock-position: 4… 5 – 10 can be met by the 28
– 23 & 29 – 24 exchange, so more principal is
4… 17 – 21 after which white could take a right
wing attack, by playing either 5.29 – 24 or
allow a chain-lock playing either 5.31 – 26 19 –
24 6.26 x 17 11 x 22 7.28 x 17 12 x 21 or 5.37
– 32 5 – 10 6.41 – 37 19 – 23 7.28 x 19 13 x
24 8.32 – 28 21 – 26 etc.
88
Another quite popular line is 4.31 – 26 14 – 19
5.40 – 35 19 x 30 6.35 x 24 10 – 14 7.24 – 20
15 x 24 8.33 – 28 22 x 33 9.38 x 20 and the
future piece at <15> promises an interesting
game.
27 22 x 31 17.37 x 28 or play the more
complex 14.31 – 27 22 x 31 15.36 x 27.
If black plays 10… 9 – 14 white will try to get a
Roozenburg attack: 11.44 – 40 3 – 9 12.50 –
45 1 – 6 13.31 – 27 22 x 31 14.36 x 27 etc.
4… 14 – 20 5.38 – 33 10 – 14 6.32 – 28
1.34 – 29 17 – 21
After 6.42 – 38 16 – 21 7.31 – 26 11 – 16 8.37
– 31 21 – 27 9.32 x 21 16 x 27 10.41 – 37 6 –
11 11.37 – 32 11 – 16 12.32 x 21 16 x 27
13.46 – 41 14 – 19 white should give up his
outpost at <24> to attack the outpost at <27>:
14.41 – 37 19 x 30 15.40 – 34 13 – 18 16.37 –
32 9 – 13 17.32 x 21 like Gantwarg – Wiersma
(1979).
Usually this opening will be the same as after
1.32 – 28 17 – 21 2.34 – 29 21 – 26 etc. like
after 1.34 – 29 17 – 21 2.39 – 33 21 – 26 3.44
– 39 11 – 17 4.50 – 44 6 – 11 5.32 – 28 17 –
21 etc.
1.34 – 30 The French opening
1.34 – 30 20 – 25
6… 16 – 21 7.37 – 32 11 – 16
8.43 – 38 6 – 11 9.31 – 27 22 x 31
10.36 x 27 21 – 26 11.41 – 36
The most frequently played continuation is
2.32 – 28 25 x 34 3.39 x 30 and after 16 – 21
4.37 – 32 21 – 26 5.32 – 27 26 x 37 6.41 x 32
15 – 20 7.46 – 41 20 – 24 the game will
continue along classical lines.
The Cheetah
2.30 – 24 19 x 30 3.25 x 24
This sharp continuation is the fastest way to
get a right wing attack from the opening, which
fully explains the name of this opening..
3… 18 – 22
After 11.41 – 37 1 – 6! The 17 – 22 threat
would force white to flee to the edge of the
board with the poor 27 – 21 x 21. Therefore
white is almost forced to play 11.41 – 36. Black
can choose between two sharp plans:
This is the sharpest continuation.
3… 18 – 23 should be answered by 4.40 – 34
4.32 – 28? 23 x 32 5.37 x 28 isn’t good for
black is going to attack the outpost repeatedly
with huge problems for white. His right wing
will be demolished.
4… 14 – 20
4… 14 – 19 5.34 – 30 25 x 34 6.39 x 30 10 –
14 7.30 – 25 19 x 30 8.25 x 34 gives white a
slight advantage. Piece 35 is centralized.
5.44 – 40 20 x 29 6.33 x 24 10 – 14 7.50 – 44
14 – 20 8.32 – 28
White should be aware of the shot after 9.39 –
33? 20 x 29 10.33 x 24 23 – 28! 11.32 x 23 12
– 18 12.23 x 21 16 x 27 13.31 x 22 13 – 18
14.22 x 13 8 x 50 B+.
8…. 23 x 32 9.37 x 28 20 x 29 10.34 x 23 and
there is nothing wrong with white’s centre
attack.
1) 11… 17 – 21 12.46 – 41 12 – 17 13.41 – 37
7 – 12 14.37 – 31 26 x 37 15.42 x 31 21 – 26
16.47 – 42 26 x 37 17.42 x 31 1 – 6 with the
idea of reducing white’s space more and more.
2) 11… 4 – 10 12.47 – 41
12.46 – 41? is wrong, for after 14 – 19 13.40 –
35 19 x 30 14.35 x 24 9 – 14 15.44 – 40 14 –
19 16.40 – 35 19 x 30 17.35 x 24 10 – 14
18.45 – 40 26 – 31! black wins a piece,
because 19.27 – 21 16 x 27 20.32 x 21 17 x 26
21.36 x 27 is met by 25 – 30 22.24 x 35 20 –
24 23.29 x 18 12 x 45 B+1 and 19.27 – 22 is
punished by 13 – 18! 20.36 x 27 18 – 23 21
4.33 – 29
89
3.28 x 19 14 x 23 4.39 – 33
21.28 x 10 17 x 46 22.10 – 4 46 – 28! 23.33 x
22 8 – 13 24.4 x 18 17 x 21 B+.
This is the modern continuation. White used to
play 4.38 – 33 with the same strategy. White
wants to get an initiative at the right wing. If
black occupies <24> white uses the power
block to put pressure. Further on in the game
white wants to control <29>. He will not play
the 33 – 28 move in the early stages of the
game, but play at the right wing. That’s why
this game type is called semi-classics, white
won’t make the game closed classical, but tries
to take <29> under control, surrounding the
black centre.
4.38 – 33 21 – 26.
A move like 4… 13 – 19 would allow white to
free his ‘big belly’ at the left wing playing 5.37 –
31 8 – 13 6.31 – 26 etc.
5.34 – 30 10 – 14 6.30 – 25 (doesn’t allow 20
– 24 which is actually an option for black after
4.39 – 33 10 – 14 5.34 – 30 21 – 26 6.30 – 25)
6… 14 – 19 7.25 x 14 9 x 20
Black can also take backwards, but white then
gets more space for getting the right wing
under control.
8.35 – 30 5 – 10 9.43 – 38
We show the critical line, white can play more
safely by 30 – 25 and then the moves 40 – 34,
44 – 40 and 49 – 43.
9… 10 – 14 10.49 – 43 4 – 9 11.40 – 35 11 –
17 12.45 – 40 7 – 11 13.39 – 34?! 20 – 25!
14.44 – 39 14 – 20 15.33 – 29 like in Wiersma
– J. v.d. Wal (1979).
12… 26 – 31! This surprising move is based on
the kingshot after 13.27 – 22? 13 – 19!! 14.24
x 4 14 – 19 15.36 x 27 8 – 13 16.4 x 18 12 x 43
17.48 x 39 19 – 23 18.28 x 19 17 x 48 B+.
13.27 – 21 16 x 27 14.32 x 21 17 x 26 15.36 x
27 14 – 19 16.40 – 35 19 x 30 17.35 x 24 9 –
14 18.44 – 40 14 – 19 19.40 – 35 19 x 30
20.35 x 24 10 – 14 21.28 – 23
22.45 – 40 loses a piece as we already saw,
so white has to defend piece 24 horizontally.
21… 13 – 19 22.24 x 13 8 x 28 23.33 x 22 14 –
19 with advantage for black.
Ottink-variation
1.34 – 30 17 – 22 2.30 – 25 11 – 17
3.31 – 26 6 – 11 4.37 – 31
Black can take a right wing attack playing 4…
22 – 27 5.32 x 21 16 x 27 6.31 x 22 18 x 27
7.41 – 37 13 – 18 or allow a fork lock after 4…
1 – 6 5.32 – 27 19 – 23 6.33 – 29 23 x 34 7.40
x 29 with the so-called Ottink-variation. Instead
of the usual 7… 13 – 19 black can play
sharper: 7… 20 – 24 5.29 x 20 15 x 24 8.45 –
40 13 – 19 9.40 – 34 19 – 23 10.34 – 29 23 x
34 11.39 x 19 14 x 23 with an interesting game
with the fork-lock.
1.31 – 27 Polish opening
This opening move gives black the opportunity
to play against white’s left wing. White allows
this in order to get surrounding chances
against the black centre.
4… 10 – 14 5.34 – 30
Important other continuations are 5.33 – 28
and 5.44 – 39.
5.33 – 28 and now 3 possibilities:
Semi-classical opening
1) 4… 14 – 19 5.44 – 39 21 – 26
5… 5 – 10? is punished by the Arc shot 27 –
22! 18 x 27 38 – 33 27 x 29 37 – 31 23 x 32 34
x 5. W+
White can try to trap the opponent playing 7.34
– 30 5 – 10? and perform the so-called coup
Raman: 8.30 – 24!! 20 x 29 (19 x 30 28 x 19 13
x 24 37 – 31 26 x 28 39 – 33 28 x 39 43 x 5
W+) 8.27 – 22 18 x 27 9.32 x 21 23 x 32
(otherwise 39 – 34 follows) 10.38 x 27 26 x 17
11.27 – 22 17 x 28 12.39 – 33 ad lib. 13.43 x 5
W+. But black can make an exchange playing
7… 26 – 31 8.37 x 26 18 – 22 9.27 x 29 19 –
1.31 – 27 19 – 23 2.33 – 28 17 – 21
After 2… 17 – 22 2.28 x 19 22 x 31 3.36 x 27
14 x 23 4.41 – 36 11 – 17 5.46 – 41 white
wants to build an cannon at his left wing. 10 –
14 6.37 – 31 14 – 19 7.38 – 33 5 – 10 8.42 –
38 10 – 14 9.41 – 37 6 – 11 10.47 – 41 1 – 6
11.34 – 29 23 x 34 12.39 x 30 like Sijbrands –
J. Palmans 2008.
1… 20 – 25 2.28 x 19 14 x 23 can potentially
lead to positions from the Russian bear (1.32 –
28 20 – 25).
90
24 10.30 x 19 13 x 44 11.50 x 39 16 – 21
12.26 x 17 11 x 44 13.43 – 39 44 x 33 14.38 x
29 with a slight edge for black. Positionally
more correct is 7.36 – 31 because black can’t
play at <17> white can play 41 – 36 at the next
move, always able to change after 11 – 17 with
27 – 21 developing his left wing and 12 – 17 is
usually prohibited because of the bomb shot,
for example: 7.36 – 31 5 – 10 8.41 – 36 10 –
14 9.34 – 30 12 – 17? 10.30 – 24! 20 x 29
11.27 – 21 16 x 27 12.32 x 12 23 x 41 13.12 x
34 W+1.
18.19 – 13! 8 x 19 19.29 – 23 ad lib. 20.37 –
31 36 x 27 21.38 – 32 ad lib. 22.42 x 4 W+.
2) 5… 13 – 19 In this case white’s positionally
correct move is 6.36 – 31 (followed by 41 – 36)
but he can try to trap his opponent playing 6.44
– 39 8 – 13 7.34 – 30!? 20 – 24? 8.27 – 22! 18
x 27 9.38 – 33 27 x 29 10.39 – 34 23 x 32
11.34 x 23 19 x 28 12.30 x 26 winning the
piece at <32>.
5… 14 – 19 6.30 – 25 21 – 26
Black can play (from the last diagram) 7 … 21
– 26 8.38 – 33! White is creating the crucial 33
/ 39 formation making 13 – 19, which would
strengthen black’s left wing (13 – 19 8 – 13 2 –
8), unattractive because of 37 – 31! 26 x 28 33
x 24 20 x 29. Usually the game continues
something like: 8… 10 – 14 9.34 – 30 14 – 19
10.30 – 25 9 – 14 11.35 – 30 4 – 9 12.40 – 35
11 – 17 13.43 – 38 20 – 24 14.49 – 43 etc.
After 6… 20 – 24 white builds the power block
playing 44 – 39 40 – 34 34 – 30 45 – 40 50 –
45 49 – 34.
7.25 x 14 9 x 20
7… 19 x 10 isn’t bad, but white gets more
space at the right wing.
3) 5… 5 – 10 6.28 x 19 14 x 23 7.44 – 39
8.35 – 30 5 – 10 9.30 – 25 10 – 14
10.44 – 39 4 – 9 11.40 – 34 20 – 24
Another logical line is 11… 11 – 17 12.45 – 40
7 – 11 13.50 – 45 17 – 21 14.34 – 30 20 – 24
15.40 – 35 11 – 17 16.49 – 44 etc.
12.45 – 40 11 – 17 13.50 – 45 14 – 20
14.25 x 14 9 x 20
Black has to dodge a famous trap, that has
made countless victims already: the coup
Lochtenberg: 7… 10 – 14? 8.27 – 22! 18 x 27
9.36 – 31 27 x 36 10.32 – 27 21 x 32 11.37 x
10 9 – 14 12.10 x 19 13 x 24 13.34 – 30 3 – 9
14.30 x 19 4 – 10
14… 9 – 13 15.40 – 34 13 x 24 16.34 – 30 4 –
9 17.30 x 19 9 – 13 18.39 – 34 13 x 24 19.34 –
30 24 – 29 20.30 – 25 20 – 24 21.25 – 20 8 –
13 22.38 – 33 29 x 38 23.20 x 29 W+1.
15.35 – 30!
Preventing 9 – 14 while 20 – 24 is met by the
stick move 20 – 14 W+.
15… 20 – 25 16.41 – 37 25 x 34 17.40 x 29 12
– 18
Black tries to get back the lost piece, at 17…
15 – 20 there is a similar shot beginning with
29 – 24 & 19 – 14.
Black tries to get control over <24> but 15.40 –
35 can lead to a fierce fight, like in the
Hoogendoorn – W. van der Kooij game in
which white managed to get control over <29>
later anyhow!
Left-wing-opening
1.31 – 27 17 – 21
91
have overlooked the simple shot after 12… 13
– 18? 13.28 – 22! 17 x 28 14.33 x 13 9 x 18
15.27 – 22 18 x 27 16.32 x 21 16 x 27 17.35 –
30 24 x 33 18.38 x 16 winning piece <27>.
Usually black plays 12… 20 – 25.
White can play the simple 2.37 – 31 21 – 26
3.32 – 28 26 x 37 4.41 x 32 developing his left
wing. 2.37 – 31 19 – 23 3.31 – 26 is also
possible, but quite boring after 20 – 24 26 x 17
11 x 31 36 x 27 24 – 29 33 x 24 23 – 28 32 x
23 18 x 20 =, but 3.41 – 37 21 – 26 4.33 – 28
11 – 17 5.28 x 19 14 x 23 6.27 – 21 16 x 27 31
x 11 6 x 17 isn’t exciting either.
3… 10 – 14 4.46 – 41 5 – 10
5.31 – 27 20 – 24 6.36 – 31 15 – 20
7.33 – 28 10 – 15 8.41 – 36 4 – 10
9.47 – 41 17 – 21 10.26 x 17 11 x 33
11.39 x 28 23 – 29 12.34 x 23 18 x 29
Playing 2.33 – 28 can lead to the same varition
as before, but if black plays 21 – 26 3.39 – 33
11 – 17 4.44 – 39 17 – 22 5.28 x 17 12 x 21
instead of 19 – 23 x 23, it’s harder for white to
get a good surrounding play, as we already
saw in the 1.33 – 28 17 – 21 Seagull opening.
6.33 – 28 7 – 12 7.50 – 44 1 – 7 8.38 – 33 7 –
11
If black changes 19 – 23 x 23 white frees his
left wing by 32 – 28 23 x 32 27 x 38.
9.43 – 38 19 – 23 10.28 x 19 14 x 23 11.33 –
28 9 – 14 12.28 x 19 14 x 23 13.38 – 33 10 –
14 14.32 – 28 23 x 32 15.27 x 38 20 – 24 white
trailing 8 temps, giving black the initiative.
13.27 – 21 16 x 27 14.31 x 22 6 – 11 leads to
an exciting game as in Valneris – Chizhov
(2001). Of course there are many more
variations in this opening, but we showed one
of the most interesting ones.
When playing this opening with black, you
have to take care for the trap called the
Mountain shot after 1.31 – 26 19 – 23 2.37 –
31 14 – 19 3.33 – 29 (this move can also be
played later on) 10 – 14 4.41 – 37 5 – 10 5.46
– 41 20 – 25 6.39 – 33
The big leap
1.31 – 27 17 – 22
White can play many moves like 2.37 – 31 19
– 23 3.31 – 26 22 x 31 4.26 x 37 or 2.32 – 28
22 x 31 3.36 x 27. However, the most exciting
continuation is:
2.36 – 31 22 – 28
2… 19 – 23 3.34 – 29 23 x 34 4.40 x 29 14 –
19 5.32 – 28 is very solid.
6… 14 – 20? 7.26 – 21!! 17 x 26 8.32 – 28 23 x
32 9.37 x 28 26 x 46 10.29 – 23 18 x 29 11.34
x 5 and black’s king is caught or 7.26 – 21 16 x
27 8.32 x 21 17 x 26 9.33 – 28 23 x 32 10.37 x
28 26 x 46 11.29 – 23 18 x 29 12.34 x 5 with
the same result.
Black can play 6… 15 – 20 7.44 – 39 10 – 15
8.50 – 44 4 – 10 9.32 – 28 23 x 32 10.37 x 28
19 – 23 11.28 x 19 13 x 24 with the fork-lock
position from 1.34 – 29 19 – 23.
3.32 x 23 19 x 28 4.33 x 22 16 – 21
5.27 x 16 18 x 36
White can also take 2.33 x 22 16- 21 3.27 x 16
18 x 36. In both cases the piece at <36>
promises an interesting fight.
The edge-opening
1.31 – 26 19 – 23 2.36 – 31 14 – 19
3.41 – 36
Rejected edge-opening
Another popular line is 3.33 – 28 20 – 24 4.39
– 33 10 – 14 5.44 – 39 14 – 20 6.41 – 36 5 –
10 7.46 – 41 10 – 14 8.34 – 29 23 x 34 9.40 x
29 18 – 23 10.29 x 18 12 x 23 11.31 – 27 7 –
12 12.45 – 40. In this position many players
1.31 – 26 17 – 21 2.26 x 17 11 x 22
92
This opening usually transposes to 1.32 – 28
17 – 22 2.28 x 17 11 x 22 3.37 – 32. If white
plays 3.37 – 31 we arrive at the same position.
8.47 – 41 21 – 26 9.39 – 33 and black can opt
for either 9… 17 – 22 or the continuation
Sijbrands chose against Cordier: 9… 15 – 20
10.44 – 39 19 – 24 11.30 x 19 13 x 24 12.49 –
44 9 – 13 13.35 – 30 24 x 35 14.29 – 23 18 x
29 15.33 x 15 with an exciting game with the
edge piece at <15> (see appendix).
Of course black can play all moves, of which
1.31 – 26 18 – 23 is a frequently played one,
but we will not elaborate on this possibilities
here.
6.43 – 38
1.35 – 30 The wild horse
6.42 – 38? is punished by 19 – 24! 7.29 x 20
22 – 28 8.32 x 23 18 x 29 9.34 x 23 25 x 45
and piece 23 will be shelled.
The sharpest of opening moves is 1.35 – 30. It
ois also the rarest opening move, but can lead
to exciting games!
6… 11 – 17 7.38 – 33 6 – 11
1.35 – 30 20 – 25 2.40 – 35
White can now choose between 8.32 – 28 and
the immediate 8.30 – 24 19 x 30 9.35 x 24 both
leading to a quick right wing attack.
2.33 – 29 15 – 20 3.29 – 23 white taking an
early centre attack is called the Agafonovopening.
2… 15 – 20 3.45 – 40 20 – 24
3… 17 – 22 is a good move too, after 4.32 – 28
20 – 24 etc. white plays with a locked right
wing, like in a Schwarzman – Chizhov world
championship match.
4.33 – 29 24 x 33 5.38 x 29

Epilogue
Many openings can be studied much deeper. If
you want to do this it is very helpful to have the
games database called Turbo Dambase,
produced by Klaas Bor. This database
contains some 300,000 games.
5… 17 – 22
5… 10 – 15 6.50 – 45 5 – 10 7.42 – 38 16 –
21! is also a popular line.
8.31 – 26 isn’t attractive now, because of 17 –
22 26 x 28 18 – 23 29 x 18 13 x 31 36 x 27 15
– 20 and white is getting locked. At 8.39 – 33
black plays 21 – 27 9.32 x 21 17 x 26. White
can choose to play 8.38 – 33 21 – 27 9.31 x 22
18 x 38 10.43 x 32 or 10.33 x 42 like Georgiev
played against Schwarzman in 2003.
