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, Jim Monaghan, Henryk Kalafut and Gerard O'Reilly.
THIS WEEK

POSITION 242

White to play and WIN 

FORSYTH NOTATION:6R1/1p5N/k7/8/1p6/6Bp/1Pr3p1/1K6:  


LAST WEEK, POSITION 241

Isaac Boleslavsky, (1919-1977)

Soviet Grandmaster. World Championship Candidate. In the 1940s he had a string of excellent results which propelled him to the top of world chess. His best result was coming equal first with Bronstein in the 1950 Candidates tournament. But recent revelations by Bronstein and Smyslov, who came 3rd, put doubt on the validity of the final outcome (see below). He narrowly lost the play-off match to decide who would be Botvinnik's challenger for the World Championship.

Lilienthal vs Boleslavsky

Moscow, 1944

Black to play and WIN 

FN:2rn4/1p2pk1p/p5p1/3Np3/P2bP3/5PB1/6PP/3R3K:

Black has an extra pawn on the queenside, a beautifully centralized Bishop, and a Rook controlling the open c-file. The double pawns are not a weakness because they are not easily attacked and besides the e6 square is a good position for the King. White cannot activate his Rook because of the threat of mate on the back rank.

 

1... Rc4!

2.a5 Nc6

Another way to win is 2... Rc5 3. Be1 e6 4.Nb6 Nc6 5. Rb1 Nxa5 6. Bxa5 Rxa5 7. Nc4 Ra1!.8. Nd6+ Ke7 9. Rxa1 Bxa110. Nxb7 Bc311. Nc5 a5 -+;

3.Be1 Ra4

4.Nb6 ...

The only way to defend the weak a-pawn. 4.Rb1? Nxa5 5. Bxa5 Rxa5 and Black is two pawns ahead;

4... Bxb6

5.axb6 ...

Black now has a powerful distant passed pawn.

5... Ke6

The King is well placed sandwiched between the pawns.

6.Kg1 Ra2

Black's Rook occupies the seventh rank to confine White's King.

7.Kf1 ...

7.Rd2 Rxd2 8. Bxd2 Kd6 9. Kf2 Kc5 10. Be3+ Nd4 -+;

7... a5

8.Rd3 a4 9.Bd2 Rb2 10.Be3 Nd4! 10...Na5 11.Bc5 Nc4 12.Ke1 Rb5 13.Ba3 Rb3 14.Rxb3 axb3 15.Bc1 b2 wins. 11.Bxd4 exd4 12.Ra3 12.Rxd4? a3 13.Ra4 a2 wins; 12... Ke5! The King advance decides the game. 13.Rxa4 d3 14.Ke1 Rxg2 White Resigns. The King will arrive on the e3 square.

A sacrifice too far ? 

It seems that Boleslavsky agreed to draw his final two games in the 1950s Candidates to give Bronstein a chance to tie for first place.

Smyslov: Boleslavsky agreed to the draws after bowing to pressure. Vainstein wanted to make sure Botvinnik was defeated, and he knew Boleslavsky didn't have a good record against the world champion. Boleslavsky drew his final game as White in a promising position against Stahlberg, while Bronstein was beating Keres in a brilliant game.

Bronstein: "Isaac Boleslavsky was leading in the Candidates' Tournament, but after a talk he had with Boris Vainstein he decided to slow down to allow me to tie for first place with him. Vainstein would try to arrange a tournament with Botvinnik, Boleslavsky and myself for the World Championship. Alas, it did not come about and we had to meet in a play-off for the right to challenge Botvinnik". "The Sorcerer's Apprentice," Cadogan Books, London, 1995
