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 Olvier Scalbert and Antonio Senatore.

THIS WEEK

POSITION 268

White to play and WIN

FORSYTH NOTATION

:8/2p1q3/p3P3/2P4p/1PBP2kP/2N3P1/7K/8:


LAST WEEK, POSITION 267

William Lewis, (1787-1870).

Chess Teacher and Writer. In 1819 he operated 'The Turk' the chess-playing automaton in the London Exhibition. Coached the leading player in England in the1830's: Alexander McDonnell. Published two important works: Series of Progrssive Lessons (1831) and Second Series of Lessons (1832). Lewis's work commands respect but theory was advancing quickly and much of his writing, especially his opening analysis, soon became obsolete. As we shall see, he made an important contribution to endgame theory.

Lewis, 1835

White to play and WIN

FORSYTH NOTATION:8/n7/Pk6/8/2K5/R7/8/8:

This position occurred in one of the match games between La Bourdonnais and Lewis's student McDonnell in 1834. Lewis was the first theoretician to find the win but his analysis was later improved on by Berger. Without the a6 pawn this position is drawn. The winning method is to break the Black blockade by taking the White King on a long journey which will end in front of his pawn. I have decided to use the top moves as found by the computer endgame tablebase as the main line. From a practical point of view these moves are not always the best but in this case they illustrate the winning idea beautifully.

1.Ra4! ...

In the game, play continued: 1.Kd5? Nb5 2.Rb3 Kxa6 3.Kc5 Na7 4.Rb8 Ka5= ;

1... Nc8

1...Nc6 2.Kd5 Na7 3.Kd6 Nb5+ (if 3...Nc6 4.Ra2 Na7 5.Kd7 Nb5 6.Kc8 and follows as at the main line) 4.Kd7 Na7 5.Ra2 Nb5 6.Kc8 and follows as at the main line.

2.Kd5 Na7

3.Kd6 Kb5

3...Nc6 4.Ra2 Na7 5.Kd7 Nb5 6.Kc8+- ;

4.Ra1 Kb6

5.Kd7 Nb5

6.Kc8 ...

White has made real progress.

6... Na7+

7.Kb8 Nc6+

8.Ka8! ...

The King has reached his destination. The blockade is broken. If 8...Na7 9.Rb1+ Nb5 10. Rxb5+ WINS.

This winning method was published by Lewis in 1835 !!
