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 Steven B. Dowd, Antonio Senatore, Rainer Staudte, Henryk Kalafut, Gerard O'Reilly and Valdir Uchoa Jr.

FORSYTH NOTATION

It is good training to try initially to solve the endings without the assistance of a chess playing programme.

LAST WEEK, POSITION 331

George Koltanowski, (1903-2000)

International Master. Belgium/American Allrounder. His playing career for Belgium straddled the two World Wars. He became his country's strongest player after the tragic early death of Edgar Colle who was also a close friend. His other great gifts as chess writer (19000 columns for the San Francisco Chronicle !!), showman and chess promoter came to the fore after he had settled in America. During his multi-faceted career he composed several chess studies of which the following is probably the most impressive.

White to play and WIN

FORSYTH NOTATION

:8/1p6/4p3/p3Nkp1/PbP2P2/8/4K3/1R2n3 w - - 0 1:

A difficult study to solve. It is not obvious how White is going to win. Material is about level. Can he create a passed pawn which can act as a decoy ? Capturing the Knight on "e1" or the Bishop at "b4"doesn't seem to work. Black is threatening to take the f-pawn and thus obtain two passed pawns which will give drawing chances. The situation of the White Knight is not very secure. Perhaps White doesn't need to worry about his Knight and can capture the offending g-pawn thus creating a powerful passed pawn.

 

1.fxg5!! ...

1.Nf3? Nxf3 2.Kxf3 g4+ 3.Kg3 e5! 4.fxe5 Kxe5 5.Rd1 b6 6.Kxg4 Ke4 7.Kg5 Ke5 8.Rd5+ Ke6 9.Kf4 Bd6+ 10.Ke4 Kd7 11.Rh5 Kc6 12.Rh6 Kc5 =;

1.Rxe1? Bxe1 2.Kxe1 gxf4 3.Nf3 (if 3.Nd7 Ke4 4.Nc5+ Kd4 5.Nxb7 Kxc4 6.Nxa5+ Kb4=) 3...Ke4 4.Ke2 e5 5.c5 Kd5 6.Kd2 Kxc5 7.Nxe5 Kb4 8.Nd3+ =;

1... Kxe5

Black accepts the gift. Capturing the pawn does not help: 1...Kxg5? 2.Rxe1 Bxe1 3.Nf3+ wins;

2.Rxb4!! axb4

There is some irony here. White is playing for another passed pawn but he creates one for the enemy.

3.Kxe1 ...

This is the point of the previous play. White reaches a pawn ending in which he has the advantage because the outside passed g-pawn ties down the enemy King. He will utilise his queenside pawns to create a further passed pawn. The Black King will have difficulty coping with two passers.

3... Kf5

3...b3 4.Kd1 Kf5 5.a5! e5 6.a6 bxa6 7.c5 follows as in main line.

Other moves lose very quickly. 3... Kd6 c5+ +-;

4.a5! ...

It is important to advance the correct pawn.

The c-pawn, which will become the passer, will promote with check.

4.c5? e5 5.c6 bxc6 6.a5 b3 7.Kd1 e4 8.a6 e3 9.a7 b2 10.Kc2 b1Q+! 11.Kxb1 e2=;

4... e5

5.a6! bxa6

6.c5 b3

7.Kd1! ...

The King moves into the square of the b-pawn.

7.Kd2?? e4 8.c6 e3+ 9.Kxe3 b2 10.c7 b1Q 11.c8Q =;

8... e4

8.c6 e3

In the battle of the passed pawns White wins because his c-pawn will promote with check thus gaining a very important tempo. The new Queen will have no difficulty in stopping Black from promoting.

9.c7 e2+

9...b2 10.c8Q+ Kxg5 11.Qb7 Wins;

10.Kxe2 b2

11.c8Q+ WINS.

A very fine study created by an engaging chess personality.
