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, Jon Palmer, Henryk Kalafut, Gerard O' Reilly, Alexander Voyna and Jim Monaghan .

White to Play and WIN

FORSYTH NOTATION

:8/3p3p/3B3k/P1Pp1p1P/8/8/5P2/1b5K w - - 0 1:

When two great composers work together on a study we expect something special and here they do not disappoint. One of the first maxims a chess beginner learns about the endgame is that most opposite-coloured Bishop endings equate to a drawn ending. The study composer is always looking for exceptions in every sphere of endgame knowledge and so the theoretical boundaries are pushed back, as we see new insights into what appears at first ordinary and mundane. This is the fascination that makes endings so absorbing.

White starts with the sacrifice of the c-pawn in order to further block the a8-h1 diagonal. Black desperately wants to get his Bishop controlling this diagonal so that the a-pawn is prevented from queening.

1.c6! Be4+!

1...dxc6 2.a6! Be4+ 3.f3! Bxf3+ 4.Kh2 c5 5.Kg3! Be4 6.Kh4 Kg7 7.Be5+ Kf7 8.Bd4! cxd4 9.a7 d3 10.a8Q wins;

2.f3! ...

This is a vital deflecting sacrifice which later gains an important tempo in the attack.

2.Kh2! dxc6 3.a6 c5 4.f3 Bxf3 5.Kg3 tranposes to the main line.

2... Bxf3+

3.Kh2! dxc6

4.a6! c5!

Black has to try and open the a8-h1 diagonal for his Bishop in order to stop the a-pawn from queening.

4...d4? 5.Kg3 5...Be4 6.Bc5!d3 7.a7 d2 8.Kh4 Kg7 9.a8Q wins;

5.Kg3! ...

5.a7? d4! 6.Kg3 Bd5 7.Kh4 Kg7=;

5... Be4

6.Kh4! ...

White threatens 11.Bf8 mate and so the Black King is forced on to a dark square which means White can carry out a blockading manoeuvre with his Bishop.

6... Kg7

7.Be5+ Kf7

8.Bd4!! ...

The important a8-h1 diagonal is blocked.

8... cxd4

9.a7 d3

10.a8Q Wins.

Since after 10... d2 11.Qa7+ Ke6 12.Qd4 the d-pawn is lost. White wins by invading on the dark squares with his King and Queen.

 

Gens Una Sumas. 
Jon Palmer wins in March.
