Lapoc Chess Board, Issue #065 -- GOTM #35

Unlocking a stubborn defense is not always easy. Sometimes waiting for a glaring error from your opponent proves unfruitful. When your adversary is playing well you might need some trickery to provoke a mistake.

Sacrifice material to gain time for a decisive attack. Tempt your opponent with the bait allowing you a crucial tempo to swoop and conquer.

Such slick maneuvering occurred in 1969 when two strong masters, Katalymov and Kaminsky, locked horns in Sochi. Remarkable sacrificial play took place, pulling the defense this way and that. Let's see if it worked.

Deflection of the Key Defender

Katalymov, Boris N - Kaminsky, Oleg M [C56]

GotM #35 - Sochi, 1969
[Connaughton, Ken]

1.e4 e5 2.Nf3

King's Knight Opening

2...Nc6 3.Bc4

Italian Game


Two Knights Defense


White opts for the most energetic continuation.
(4.d3; 4.Nc3; 4.Qe2)

4...exd4 5.e5

Again White pushes the issue.

(5.0-0; 5.Nxd4)


Game position after 5...d5



(6.exd6 Qxd6; 6.exf6 dxc4)

6...Nd7 7.0-0 Be7 8.Re1 0-0 9.Bf4

White shores up his e-pawn which will have a remarkable future in the game.

(9.Nbd2; 9.Bxc6)

9...Ndb8 10.c3 dxc3

Game position after 10...dxc3

This move does indeed allow White to develop his Knight but Black creates a passed pawn with this exchange.


White has a lead in development with the Black King's Knight now sitting in his brother's home square, the first player also has a spatial advantage granting his pieces considerable mobility.

11...d4 12.Ne4 Bf5 13.Bd3 Bg6 14.Rc1 Nb4 15.Bb1 c5

Game position after 15...c5

Black is hoping that his c and d-pawns will give him counterplay and tie down some of White's resources.

16.h4 Nd5 17.Bh2 Nd7 18.Nfg5 h6 19.h5

Game position after 19.h5

White sets in train an exchange sequence that would seem to help Black but he sees that the resulting position holds new assets for him.

19...Bxh5 20.Qxh5 Bxg5 21.Nxg5 Qxg5 22.Qf3 N7b6 23.Rxc5

Black's passed pawn now looks much more frail.

23...Rfc8 24.b4

(24.Rxd5?? Rc1 25.Qe4 Nxd5 26.Rf1 Rxf1+ 27.Kxf1 Qc1+ 28.Ke2 Qxb2+ 29.Kf3 g6 30.Bd3 Qa3 31.e6 f5 32.Qxd5 Qxd3+ 33.Kf4 Re8 34.a4-+)

24...Nxb4 25.e6!!

Game position after 25.e6!!

And the reasoning for the simplifying becomes clear. White will sacrifice his Rook for a monster passed pawn and a powerful attack.

(25.Rxc8+; 25.Bf4)

25...Qxc5 26.Qxf7+ Kh8 27.e7

White's remaining pieces are brilliantly placed to threaten both promotion and a Kingside attack and Black will find it difficult to parry both dangers.


Cutting off the light square Bishop' s view of h7, opening up the Black Queen's gaze on f2 and reminding White that there are two passers on the board.


White embarks on the final assault and Black's subsequent responses will be absolutely forced.

28...Rg8 29.Qg6

The forcing sequence continues...

29...Qc6 30.Bxg7+!

Game position after 30.Bxg7+!

Another clever sacrifice finally compromises Black's back rank fatally.

30...Rxg7 31.e8Q+

And there it is.

31...Rxe8 32.Rxe8+ Qxe8 33.Qxe8+ Rg8 34.Qe5+ Rg7 35.Qf4 N6d5 36.Qf8+ Kh7 37.a3

Game position after 37.a3

Black resigns, with the fall of his passed pawn go any chances for him in this game. The Queen and Bishop will co-ordinate to pick off and defeat Black's remaining forces.
