PRACTICAL CHESS ENDGAME 25/02/2001

Editor: Brian Gosling

ALL RIGHTS RESERVED

Welcome to this active site. Each week I am going to present to you a 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, Alexander Vojna, Allan Bennett, and Henrk Kalafut.

Attila Koranyi, 1955 

White to play & WIN

FORSYTH NOTATION:5k2/B5p1/8/2P4B/7p/8/1r6/2nK4:

Although Black is ahead on material he has to contend with White's powerful Bishops and the passed c-pawn. He has badly placed pieces which at the moment seem no match for the quickly advancing pawn. His only hope is to go for a draw by giving up his Rook for the c-pawn, but how can this aim be achieved? The immediate problem is the threat against the Knight. Can Black organise his pieces against the dangerous c-pawn and counterattack with his h-pawn?

1.c6! ...

1.Kxc1 Rb7 2.Bb6 h3 3.Bf3 Rf7 4.Bd5 h2 5.c6 Ke7 6.c7 Kd7 7.Be6+ Kd6 8.c8Q h1Q+ with a likely draw.

1... Nb3

1... Rb3? 2. Bc5+ Kg8 3. c7 and the c-pawn will promote.

1... Nd3 2. Bc5+ Nxc5 and follows as at the main line.

1...Ke7 2.Kxc1 Ra2 3.Bc5+ Kf6 4.c7 Ra8 5.Bg4 Kg5 6c8Q Rxc8 7.Bxc8 and the Bishops win against Black's pawns.

Black is threatening to bring his Rook to the c- or d-file but White has a brilliant move.

2.Bc5+! Nxc5

Black has to take the Bishop or otherwise the c-pawn will promote.

3.c7 Rb1+

He has nothing left to go for, except a series of checks by the Rook and hope the King lands on the wrong square.

4.Ke2! ... 

The Monarch starts on a long meaningful journey.

4.Kc2? Rb2+ 5.Kxb2 Na4+ 6.Kc2 Nb6 7.Bg4 Ke7 8.c8N+ Nxc8 9.Bxc8 =; 

4... Rb2+  

5.Kf1! Rb1+  

6.Kg2 Rb2+  

7.Kh3 Rb3+  

8.Kxh4! ... 

8. Bf3 Rxf3+ 9. Kxh4 Rf6! 10. c8Q+ Kf7 11. Qxc5 =;

 8... g5+  

9.Kg4 Rb4+  

10.Kf5 Rf4+

11.Kg6...

The King has avoided the Knight forks and is now in a advantageous position. 

11... Rf6+

The Rook is sacrificed in order to get the Knight transferred to b6. 

12.Kxf6 Nd7+

13.Kxg5? Nb6=;

 13.Ke6! Nb6 

14.Bg4 Nc8 

There are a number of ways to win from this position. The composers solution was as follows: 15.Kf6 15. Kd5 Ne7+ (15... Na7 16. Kc5 wins) 16. Kd6 Kf7 (16... Ke8 17. Bh5+ Kf8 18. Kd7 wins) 17. Kd7 Kf8 (17... Kf6 18. Ke8 wins) 18. Bh5 g4 19. Bxg4 Kf7 20. Be6+ Kf6 21. Kd6 wins; 15...Ne7 16.Kxg5 Kg8 16...Kf7 17.Bd7 Kf8 18.Kg4 Kf7 19.Ke5 The king goes to the other side of the board to support the pawn. 17.Be6 Kg7 White must not allow the the King to escape via f6; 18.Bc4 Nc8 19.Bb3 Ne7 20.Be6 Kf8 21.Kf6 Ke8 22.Kg7 WINS.

A very deep ending which has a number of connected phases. The structure of this type of composed ending, with different phases, has become known as the Ultra Modern Endgame Study. This study finally resolved itself into BPvN ending, which has been extensively examined in John Nunn's brilliant book: Secrets of Minor Piece Endings (1995).
