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, Henryk Kalafut, Rainer Staudte, Gerard O'Reilly, Valdir Uchoa Jr, Jon Palmer and Yuriy Steschenko.
THIS WEEK

POSITION 326

White to play and WIN

FORSYTH NOTATION :6k1/5b2/pn1N2pp/3p4/2pr1PP1/5B1P/P4PK1/4R3 w - - 0 1:

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

LAST WEEK, POSITION 325

Pal Benko, (1928-).

International Grandmaster. World Championship Candidate. Endgame Study Composer. Won the Hungarian Championship in 1948 at the age of 20. Later settled in the USA where he won the American Open a record eight times. His selfless sacrifice of his place in the Interzonal at Palma de Mallorca (1970) made way for Bobby Fischer's successful 1972 challenge for the World Title. Revised Reuben Fine's classic endgame text: Basic Chess Endings (2003).

P. Benko, 1980

White to play and WIN

FORSYTH NOTATION :8/8/8/KP3Pk1/8/8/7n/8 w - - 0 1:

If there was no White pawn at "f5" which meant the Knight was against a lone passed b-pawn then Black could draw this ending. The general rule for these type of endings is if he can get his Knight back to guard any square on the queening file ahead of the pawn which in this case is the b-file then Black draws. If the Knight is too far away from the passed pawn, a saving idea is to threaten a check to fork the new Queen and King. In the above position the situation is complicated by the presence of the White pawn at "f5" which restricts Black's defensive possibilities. The Knight finds itself overworked tackling two passed pawns. White has to play accurately in order to achieve what at first may appear to be a relatively simple win.

1.Kb6!! ...

1.b6? Ng4 2.b7 Ne5 3.Kb6 Nd7+ 4.Kc7 Nc5 5.b8Q Na6+ = The Knight fork saves the day;

1... Ng4

1...Nf3 2.Kc7 Nd4 3.b6 Nb3 4.Kd6! Na5 5.Ke6 Nc6 6.f6! +-;

1...Kxf5 2.Kc7! Nf3 3.b6 Ne5 4.b7 +-;

2.Kc7! Ne3

2...Nf6 3.Kd6! Ne4+ 4.Kc6 Nd2 5.Kd5! Nb3 6.b6 Na5 7.Ke6 Nc6 8.f6! with a win.

3.Kd7! Nd5

3...Nc4 4.Ke6! Nb6 5.f6 Kg6 6.Ke7! etc. as in main line.

4.Kd6! Nb6

The Knight takes care of the b-pawn but now the f-pawn becomes the centre of attention.

5.Ke6! Kh6

6.f6 Kg6!

An important stage in the ending is reached. Black's defence seems to hold. Pushing the f-pawn only draws: 7.f7 Kg7 8. Ke7 Nd5+ 9.Ke8 Nf6+ 10.Kd8 Kd8 11.Kxf7=; But by passing the move over to Black White can win !!

7.Ke7! Nd5+

The poor Knight is overworked tackling both passed pawns.

8.Kd6! Nb6

9.Ke6! ...

We reach the same position as after move 6...Kg6 and he has to move again !! White makes progress.

9... Kh7

10.Ke7! ...

10.f7? Kg7 11.Ke7 Nd5+ 12.Ke8 Nf6+ 13.Kd8 Kxf7 14.b6 Ke6 15.b7 Nd7 =;

10... Nd5+

10...Nc8+ 11.Kd7 Nb6+ 12.Ke8 +-;

11.Kd6! Nb6

12.Kc6! Nc4

13.Kd7 Kg6

14.Ke7! Ne5

14...Nb6 15.f7 Nc8+ 16.Kd8 +-;

15.b6 Nc6+

Black's defence is at an end. He can't hold back both pawns.

16.Kd6 Nd8

17.Kd7 Nb7

18.Ke7! Wins.

Benko's greatest contribution to the endgame is as reviser of Reuben Fine's brilliant classic Basic Chess Ending (Revised by Benko 2003). It is unfortunate that in the new edition acknowledgement is omitted of the help and support of Fine's friend, Fred Reinfeld. It is also to be regretted that this otherwise excellent book still does not have an index.
