25. Tactical freeze out
A beautiful way to win a game is to get a position where all your opponents moves are tactically punished.
1.34 – 30! 20 – 25
2.39 – 34 12 – 17
3.48 – 42!
Black is tactically frozen out. 17 – 22 is met by a coup Philippe. So black has no good move left.
Mensonidus – Baba Sy
The famous player from Senegal played a very smart move, based on several shots.
1… 3 – 9!!
We will discuss all possible moves for white now:
2.39 – 34 24 – 29! 3.33 x 24 19 x 48 4.28 x 8 48 x 22 and black wins, for example: 5.8 – 3 22 – 31! 6.3 x 25 15 – 20! 7.25 x 22 31 x 45 B+.
2.40 – 34 24 – 29! 3.33 x 24 20 x 40 4.35 x 44 18 – 22 5.27 x 29 16 – 21 6.26 x 17 11 x 31 7.36 x 27 19 – 23 8.29 x 18 13 x 31 (Coup Raichenbach) B+.
2.26 – 21 24 – 30! 3.35 x 24 20 x 29 (also possible is 19 x 30 28 x 8 7 – 12 8 x 17 11 x 42 38 x 47 16 x 49 B+) 4.33 x 24 19 x 30 5.28 x 17 11 x 35 (Coup Royal) B+.
2.37 – 31 24 – 30 3.35 x 24 20 x 29 4.28 x 8 9 – 13 8 x 19 18 – 22 27 x 18 30 – 34 39 x 30 (or 40 x 29) 16 – 21 26 x 17 11 x 44 B+.
The best move is 2.28 – 22 after which black will try to take advantage of the weak position of piece 22. 2.28 – 22 7 – 12 3.37 – 31 9 – 14 4.33 – 28 20 – 25 5.40 – 34 23 – 29! 6.34 x 23 18 x 29 7.39 – 34 29 x 40 8.35 x 44 12 – 17! 9.43 – 39 (after 9.38 – 33 24 – 29! 10.33 x 24 19 x 30 11.43 – 39 30 – 34 12.39 x 30 25 x 34 white is frozen out) 17 – 21 12.26 x 17 13 – 18 13.22 x 13 11 x 42 14.13 – 8 42 – 48 and black will win the endgame.
White has a central triangle but more important is that black controls the wings. With the help of some shots black can freeze out his opponent who is to move.
In the game white played 37 – 31 allowing his opponent to force a win.
1.37 – 31 11 – 16!
The exchange with 2.31 – 26 16 x 27 3.32 x 21 allows black to take the shot 19 – 23! 4.28 x 30 25 x 32 B+.
2.31 – 27 18 – 22!
3.27 x 9 16 x 27
4.32 x 21 8 - 13
5.9 x 18 12 x 34
The only other sensible move for white was 1.21 – 16.
Not possible is 1.45 – 40 or 1.32 - 27 because of 19 – 23! etc. B+.
1.39 – 34 18 – 23 faces white with the horrible threat 24 – 29 +.
1.21 – 16 18 – 23!
Now 2.28 – 22 is punished by 12 – 18!! 3.45 – 40 (3.32 – 27 23 – 28 B+1) 18 x 27 4.32 x 21 23 – 28 5.33 x 22 13 – 18 5.22 x 2 19 - 23 6.2 x 30 25 x 41 B+.
2.45 – 40 12 – 18
Still white can’t break the classical pattern with 28 – 22 x 21 because of the same shot as before.
3.40 – 34 8 – 12
4.37 – 31 11 - 17
5.31 – 27 17 - 21
6.28 – 22 21 – 26
It’s a tactical freeze out. The only white move 7.33 – 28 is answered by 26 – 31 27 x 36 18 x 27 32 x 21 23 x 43 39 x 48 24 – 30 35 x 24 19 x 39 B+.
1... 24 - 29?
2.33 x 24 20 x 29
Black went to the graveyard (29). With the next exchange white takes control over the situation.
3.35 - 30! 25 x 34
4.39 x 30
Black can’t play at his left wing. After 14 – 20 or 15 – 20 white plays 30 – 24 +. Black must play his strongest defending piece.
4… 3 - 8
5.44 - 40 11 – 17
Black can’t play 14 – 20 because of the shot 6.30 – 24! 19 x 30 7.28 x 19 13 x 24 8.27 – 21 16 x 27 9.31 x 4 +. The next exchange weakens blacks right wing.
6.27 - 21! 16 x 27
7.31 x 11 06 x 17
8.36 – 31!
Blacks moves are running out. This time 14 – 20 is answered by 9.30 – 24 19 x 30 10.28 x 19 13 x 24 11.26 – 21! 17 x 39 12.40 – 34 29 x 40 13.45 x 3 (24 – 29 14.3 - 25) +. So, black has no good move left, because what black plays is no solution to his problems at all.
8... 17 - 21
9.26 x 17 12 x 21
10.31 - 26! 18 - 22
11.28 x 17! 21 x 12
12.26 - 21 Threatening with 21 – 17 12 x 21 32 – 28 23 x 32 38 x 16 with a breakthrough. 12... 12 - 18
13.21 - 16 18 - 22
14.32 - 28 22 x 33
15.40 – 34 29 x 40
16.38 x 18 13 x 22
17.45 x 34
Piece 16 walked to king and white won.
Black’s
last move 10 – 15 was too slow. He forgot to close the gap at 13.
Now white can freeze out his opponent in a nice way.
1.37 – 32! 26 x 37
2.42 x 31 8 – 13
3.48 – 43!
White uses piece 45 to threaten 44 – 40. The threat can’t be parried by 3 - 8 because of 44 – 40 and after 27 – 21 +.
3… 24 – 30 4.39 – 33!
Threatening both 28 – 23 and 44 – 40.
4… 30 – 35
5.33 – 29! 3 - 8
5… 15 – 20 6.44 – 40! etc. +
6.29 – 24!
White is patient. He doesn’t take the king shot 44 – 40? 45 x 23 28 x 19 13 x 24 27 – 21 16 x 27 31 x 2 because the king is caught: 15 – 20 2 x 30 35 x 24 =.
After 29 – 24 black is tactically frozen out. He has no good reply at the 24 – 19 threat.
