PRACTICAL CHESS ENDGAME 30/09/2001

Editor: Brian Gosling

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 Antonio Senatore, Jim Monaghan, Oliver Scalbert and Gerard O'Reilly.

LAST WEEK, POSITION 209

Heinrich Meyer, (1839-1928).

Endgame and problem composer. Born near Hanover but later moved to England. Chess editor of the Boy's Own Paper . His "Longest Endgame" based on a two Knights against pawn position of Chapais, achieved wide publicity. His international notation in which the six types of chessmen are indicated by the letters K to P, was confusing so never a great success. He is featured in the The Chess Bouquet (1897) which is a collection of the work of Problem composers of the 19th century.

The Chess Bouquet, 1897

White to Play & WIN

FORSYTH NOTATION:8/8/5K1k/4p3/4p3/4N3/2N5/8:

Meyer had some knowledge of this material and composed this difficult study which is not found in the main database on studies. The play comes down to a theorectical endgame NNvP which was much analysed by Troitzky and who worked out the technique for this class of ending. The winning idea is to restrain the Black King's movements by careful use of the King and Knight, driving him into a corner which is near to where the other Knight is blockading the e-pawn. Once the Black King is confined, the blockading Knight goes to deliver mate before the passed e-pawn influences the outcome.

2.Kf7 Kh6

3.N1g2 ...

The two Knights form a barrier which confines the King.

4.Kg7 Kh5

5.Kf6 Kh6

6.Nh4 Kh7

The Knight at e3 blockades the pawns and only takes on an active role in the mating attack at the end.

Troitzky's analysis of this difficult ending NNvP is found in his book of 360 studies. Chess Studies (1937). It remains the most thorough examination of an ending, unaided by computer analysis, ever carried out by a human analyst.

The ending NNvP is very rare in practical play but it does occur from time to time. A serious student of the endgame should know some of the theory. The Hungarian/Soviet Grandmaster Lilienthal obtained this class of ending on a number of occasions and much to Botvinnik's dismay (Championship Chess 1948), in o-t-b play he was never able to discover the path to victory !!
