ALL RIGHTS RESERVED

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, Henryk Kalafut, Gerard O'Reilly, Rainer Staudte, Steven B. Dowd and Valdir Uchoa Jr.
THIS WEEK

POSITION 342

Black to play and Win

FORSYTH NOTATION :8/8/2pp1k2/1pp1pP2/4P3/P1PK2p1/1P2R1P1/5r2 b - - 0 1:

It is good training to try initially to solve the endings without the assistance of a chess playing programme.

LAST WEEK, POSITION 341

Alexander Herbstman, (1900-82).

Soviet Study Composer and Author. He has over 300 compositions to his credit and has won many prizes. In December 1979 he emigrated to Sweden, where he died, after a long and distinguished career.

Herbstman, 1948

White to play and DRAW

FORSYTH NOTATION:8/7K/1R5B/5k2/1p6/1PP5/pb6/8 w - - 0 1:

Black is soon to have a substantial material advantage with the promotion of the a-pawn. White cannot stop the promotion but does he have a perpetual to force the draw ?

1.Rb5+! ...

1.Ra6? Ba3! 2.Rf6+ Kxf6 3.Bg7+ Kf5 4.c4 Bc1 5.c5 Bd2 6.c6 Ke6 7.c7 Kd7 8.Be5 Bc3-+;

1...Ke4 2.Rxb4+ Kd3 3.Ra4 a1Q 4.Rxa1 Bxa1 5.c4 Bd4 6.Kg6 Kc3= ;

2.Ra5! ...

This move is played, not with the idea of stopping the pawn from promoting, but diverting the Black Bishop from the important a1-h8 diagonal.

2... Ba3

3.Bg7!! ...

The Bishop is going to indirectly attack the new Queen along the diagonal. White's defence starts to take shape

3... a1Q

4.Re5+ Kf7

4...Kd6 5.Rd5+ Kc6 6.Rc5+ etc. as in main line.

5.Rf5+ Ke6

6.Re5+ Kd6

7.Rd5+!! ...

Now we see the brilliant idea behind the defence. The Rook cannot be taken because White has a discovered attack with a check c4+ and the Queen will be captured by the Bishop. The Black King cannot escape the attention of the Rook without the loss of the Queen.

7... Kc6

7...Kxd5 8.c4+ Ke4 9.Bxa1 =;

8.Rc5+ Kb6

8...Kxc5 9.cxb4+ Kxb4 10.Bxa1 =;

9.Rb5+ Ka6

10.Ra5+ Kb6

10...Kxa5 11.cxb4+ Kxb4 12.Bxa1 =;

11.Rb5+DRAW

Draw by Perpetual check. The King cannot flee from the attention of the Rook. The Rook cannot be captured when it is checking at a5, b5, c5, d5 because of the discovered attack leading to the loss of the Queen and a certain draw. An ingenius defence.
