Welcome to this active site. Each week I am going to present to you an endgame position for you to solve or to workout the best continuation. Computer analysis will also be considered. Some of these positions will come from actual historical games. Others will be composed endgame studies, but all the solutions will be relevant to the practical game. The new position will occur each SUNDAY and I will always be pleased to receive POSITIVE feedback about the positions and the analysis and I will try to acknowledge these where relevant.

Thanks to Antonio Senatore, Jay Ramanathan, Gerald O'Reilly, Henryk Kalafut, Alexander Voyna, Jon Palmer, Rainer Staudte, Valdmir Uchoa and Olivier Scalbert.

LAST WEEK, POSITION 316

Laszlo Szabo, (1917-1998)

Hungarian Grandmaster who survived the horror of forced labour service and imprisonment in the Second World War to become one of the strongest non-Soviet players of the post-war period. He played in three Candidate tournaments and it was at Amsterdam 1956 that he came close to the world championship: he came equal third with a group of Soviet grandmasters just behind Smyslov and Keres.

Hastings, 1938/39

White to play and WIN

FORSYTH NOTATION

:8/2p5/7p/pP4pP/3k2P1/4pP2/1P2K3/8 w - - 0 1:

White has the opportunity of a winning break on the Kingside with f4 but first he passes the move to Black. By playing 1.b3! the Black monarch is forced out of position and White gains important tempi for the pawn push. The resulting queen ending is very complicated, but exciting and worth playing through. The White monarch escapes the checks by hiding behind its own passed b-pawn.

 

1.b3! ...

1.f4? is premature: 1... gxf4 2.g5 hxg5 3.h6 f3+ 4.Kxf3 Kd3 5.h7 e2 6.h8Q e1Q 7.Qd8+ Kc4 8.Qxc7+ Kxb5 -+;

1... Kc3

1...Kd5? 2.Kxe3 Ke5 3.f4+ gxf4+ 4.Kf3 Ke6 5.Kxf4 Kf6 6.Ke4 Ke6 7.Kd4 Kd6 8.g5+-

2.f4! ...

White must create the passed pawn without delay. Capturing the e-pawn would throw away the win: 2.Kxe3? Kxb3! 3.f4 gxf4+ 4.Kd3 a4 5.g5 a3 6.g6 a2 7.g7 a1Q 8.g8Q+ Kb4 9.Qc4+ Ka3=;

2... gxf4

2...Kxb3 3.fxg5 hxg5 4.h6 a4 5.h7 a3 6.h8Q+-;

3.g5! Kd4

3...hxg5 4.h6 Kxb3 5.h7 a4 6.h8Q a3 7.Qg8+ Kb2 8.Qg7+ Kb3 9.Qxc7 a2 10.Qe5+- ;

9.Qxc7+ ...

9.h6 Qh1+ 10.Kg4 Qxh6 11.Qxc7+ Kxb3 12.Qxa5 Qe6+=;

9... Kxb3

White's winning method is to push the b-pawn as fast as he can. Black counter-attacks by checking.

10.b6 ...

10... Qd1+

10...Qh1+ 11.Kf2! Qxh5 12.b7+-;

11.Kg3 Qe1+!

This move is stronger than 11... Qxh5 which was played in the game and which after 12.b7! Black resigned. White escapes the checks by reaching a6 or a7 from which it is possible to set up a cross-check on b6: 12...Qg5+ 13.Kf3 Qf5+ 14.Ke3 Qg5+ 15.Kd4 Qg1+ 16.Kd5 Qg5+ 17.Kc6 Qg6+ 18.Kb5 Qd3+ 19.Kb6 Qd4+ 20.Ka6 Qd3+ 21.Ka7 Qd4+ 22.Qb6+ wins.

11...Qe1+! makes the winning process more difficult. The King escapes the checks by moving up the board and then hiding behind its own b-pawn. 12.Kg4! Qe6+ 13.Kg5 Qe3+ 14.Kg6 Qe4+ 15.Kg7 Qg4+ 16.Kf8! Qb4+ 17.Ke8 Qb5+ 18.Kd8 Qd5+ 19.Qd7! Qg5+ 20.Kc7 Qc5+ 21.Qc6 Qe5+ 22.Kc8 Qh8+ 23.Kb7 Qe5 24.Ka6 a4 25.b7 Qb8 26.Kb6 a3 27.Qc7 wins.
