PRACTICAL CHESS ENDGAME 28/5/2000

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 Henryk Kalafut, Paul Cheng, Federico Giallombardo and Olivier Scalbert.

White to play & DRAW

 

FORSYTH NOTATION:5r2/K5pP/P1kpp1P1/8/3pN3/8/8/8:  

Black has a significant material advantage: Rook and pawn against Knight. But White has serious counter-chances due to the a-pawn and the protected passed h-pawn and wastes no time in bringing the Knight over to aid the h-pawn's attempt to promote.

1.Nf6!...

The Knight cannot be taken. This move is superior to 1.Nxd6? Kxd6 2.Kb7 d3 3.a7 d2 4.a8Q Rxa8 5.Kxa8 d1Q 6.h8Q Qa1+ 7.Kb7 Qb1+ 8.Ka7 Qxg6 and Black has a won Queen and pawn ending; 1.Ng5? d3 2.Nxe6 Rh8 3.Nd4+ The Knight has to stop the d-pawn from promoting; 3...Kd7 4.Nf3 Ke7 5.Kb7 Kf6 6.a7 Kg6 7.a8Q Rxa8 8.Kxa8 Ka7 and the pawns win against the Knight.

1...Rh8

White was threatening to play the Knight to g8 so the Rook has no option but to blockade the pawn. 1...d3? 2.Ng8 d2 3.h8Q d1Q 4.Ne7+ Kc7 5.Qxf8 and Black has to take the perpetual.

2.Ng8...

The Rook is now walled in and White is threatening to bring his passed a-pawn into the game. Computer analysis indicates that 2.Ng4 also draws; 2... Kc7 3.Ne5 Re8 4.Nd3 Kc6 5. Nb4+ Kb5 6.Nd3 Kc4 7.Kb7 Kxd3 8.a7 Re7+ and Black has to take the draw by playing the Rook to e7-e8 checking the monarch when it steps on the 7th rank. Neither pawns can promote.

2... Kc7!

2...d3? 3.Kb8 and the a-pawn is liberated.

3.Ka8 d3

4.a7 Kc8

Black's move is forced and White has no better alternative than:

5.Ne7+ Kc7+

6.Ng8 Kc8

7.Ne7+ Kd7+

8.Ng8! ...

8.Kb7? d2 9.a8Q Rxa8 10.Kxa8 d1Q 11.h8Q Qa1+ 12.Kb7 Kxe7-+

8...d2

9.Kb8...

9.Kb7? d1Q 10.a8Q Qh1+ and Black wins.

9...d1Q

10.a8Q Qb1+

10...Qd4?? 11.Qb7+ Ke8 12.Qe7#

11.Qb7+ Qxb7+ 12.Kxb7 d5 13.Nh6! This manoeuvre with the Knight is sufficient to draw. 13...d4 14.Nf7 Re8 Pushing the d-pawn and allowing the Rook to be taken also leads to a draw14...d315.Nxh8 d2 16. Nf7 d1Q 17.h8Q=; 15.Nh6! Rh8 16.Nf7 It will be a DRAW by repetition.

A difficult and deep study but fully deserving its first prize in a study tourney. Many of the variations were finely balanced with ideas often repeating. A wonderful work of art.
