PRACTICAL CHESS ENDGAME 29/04/2001

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 Ken W Smith, Jim Monaghan, Graham White, Detlef Groth, Antonio Senatore, Gerard O'Reilly, Paul Cheng, and Henryk Kalafut.

Josef Moravec, (1882-1969).

A brilliant first generation Czech composer who had a long and distinguished career. He has over 200 endgame studies to his credit.

J. Moravec, 1913 

White to play & WIN

 

  FORSYTH NOTATION:7K/6p1/8/7p/8/8/R7/6k1:

This study was a favourite with Gerald Abrahams, the late English chess player and writer. Here we have an example of line interference of a diagonal by a passive pawn. It is important that the long diagonal a1-h8 remains blocked, so that it cannot be used by a potential new Black Queen. The reason for this will become obvious later. The capture of the g-pawn at the beginning cannot be entertained so the early King move to h7, bypassing the pawn can be understood. The White King chases the h-pawn and hopes to set up a mating attack with the Rook, against the enemy Monarch.

1.Kh7!! ...

1.Kxg7? h4 2.Kg6 h3 3.Kg5 h2 4.Kg4 h1Q 5.Ra1+ ( 5.Kg3? Qh8 --+) 5...Kg2 6.Rxh1 Kxh1 draw;

1.Ra5? h4 2.Rh5 g5! 3.Rxg5+ Kf2=;

1... h4

1...g5 2.Kg6 g4 3.Kg5! ( 3.Kxh5? g3 4.Kg4 g2 =) 3...g3 4.Kf4 h4 (4...g2 5.Kf3! wins but if 5.Kg3? h4+ 6.Kf3 h3 7.Kg3 Kh1 8.Ra1+ g1Q+ 9.Rxg1+ Kxg1 10.Kxh3=) 5.Kf3 Kh1 6.Ra4 g2 7.Rxh4+ wins;

2.Kg6 h3

3.Kg5 h2

4.Kg4 g5!

This move was never considered by the composer but is Black's best try. Other moves lose quickly:

4...h1Q? ( This Queen promotion would have worked if the long diagonal a1-h8 had not been blocked by the unfortunate g-pawn because Black could have guarded against the Ra1 mating threat with ...Qh8!! ) 5.Kg3 Kf1 6.Ra1+ wins;

4...h1N? 5.Kf3 g5 6.Rd2 g4+ 7.Kxg4 Kf1 8.Kf3 Ke1 9.Ra2 Kd1 10.Kg2 Kc1 11.Kxh1 wins;

5.Kg3 ...

This is the only move that wins and Black's reply is forced. The ending now enters another phase.

5... h1N+

6.Kf3 g4+

7.Kxg4 Nf2+

8.Kf3 ...

8.Kg3 also wins.

8... Nd3

The strategy in the R v N ending is to keep the Knight isolated, restrict its movement, and use mating threats or a double attack to win the piece.

8...Nh3? 9.Ra5 Kh1 10.Rh5 Kh2 11.Rh8 +-;

9.Ra4 Kh2

9...Nc5 10.Ra1+ Kh2 11.Rd1 Ne6 12.Rd5 Kg1 13.Kg3 Kf1 14.Rf5+ Ke2 15.Re5+ wins.

10.Rh4+ Kg1 11.Rd4 Nc5 12.Rd5 Ne6 13.Kg3 Kf1 14.Rf5+ Ke2 15.Re5+ Kd3 16.Rxe6 White wins.

A wonderful classical study with some interesting variations and now with a modern extension. Gerald Abrahams looked upon it as an education in itself. It teaches (a) something about the speed of Kings; (b) A promotion may be rendered useless by a mating net; (c) Learning about a duel between a Knight and Rook.
