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, Jon Palmer, Valdir Uchoa Jr and Yuriy Steschenko.

FORSYTH NOTATION :3r4/8/3pR3/K7/7p/p2N4/4P3/3k4 w - - 0 1:

LAST WEEK, POSITION 326

Bent Larsen, (1935-).

White to play and WIN

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

The connected passed pawns look menacing but White's pieces are more active and give him the opportunity to occupy the seventh rank. As Nimzowitsch taught a long time ago, a Rook on the 7th in the endgame can often be decisive. It can confine the enemy King and issue powerful attacking threats. Although Black gets a new Queen the White pieces combine beautifully to bring about the enemy downfall. The following main line are the moves played in the actual game.

1.Rb1! ...

Another way to win is to play: 1.Re7 Rxf4 2.Nxf7 Rxf7 3.Re6 Rb7 4.Rxg6+ Kh7 5.Rd6 c3 6.Rc6 d4 7.Be4+ Kg7 8.Rg6+ Kf7 9.Rxh6 Re7 10.Kf3 Nc4 11.Rh7+ Kf8 12.Rxe7Kxe7 13.Ke2 Nd6 14.Bc2 and the kingside pawns will take the day.

1... Nd7

1...c3? 2.Nxf7 c2 3.Nxh6+ Kg7 4.Rc1 Kxh6 5.g5+ Kg7 6.Rxc2 Rxf4 7.Rc7+ Rf7 8.Rc6 Rb7 9.Rd6 Nc4 10.Rxd5 Wins;

1...Na4? 2.Rb8+ Kg7 3.Rb7 Rxf4 4.Bxd5 +-;

2.Rb7 ...

The Rook seizes the seventh rank and this will prove more dangerous than the threat of the advancing c-pawn.

2... c3

2...Be6? 3.f5!

3.Rc7 ....

He must keep his eye on the c-pawn. Capturing the Knight would lead to White fighting for the draw: 3.Rxd7? c2! 4.Rc7 Rc4! 5.Rxf7 c1Q 6.Bxd5 Rc5 7.Be6 Rc6! 8.f5 gxf5 9.Rf6+ Kh7 10.Nxf5 h5 11.Rf7+ Kh8 12.Rf8+ Kh7 =;

3... Rxf4

3... c2 4.Rxc2 Rxf4 5.Nxf7 Kxf7 6.Bxd5+ Ke7 7.Rc6 Rf6 8.Rxf6 Nxf6 9.Bb7 a5 10.f4 when the extra pawn in the Bishop vs Knight ending should win for White.

4.Nxf7 Rc4?

Black puts his hope in the promotion of the c-pawn but it is not his strongest defence. 4...Kxf7 allows Black to fight on a piece down but having dangerous pawns. But the win is not in doubt 5.Rxd7+ Ke6 6.Rc7 d4 7.Bb7 (7.Rc6+ Ke5 8.h4 g5 9.hxg5 hxg5 10.Kg3 Rf7 11.Rc5+ Kd6 12.Rd5+ Ke6 13.Rxd4 +- ) 7... a5 8.Kf1 Ke5 9.Ke2 Rf6 10.Rc5+ Kd6 11.Rc6+ Ke5 12.Rxf6 Kxf6 13.f4 winning.

5.Rxd7! c2

6.Ne5! c1Q

Black pays a high price for the new Queen.

6...Rc3? 7.Bxd5 Kf8 8.Nxg6+ Ke8 9.Re7+ Kd8 10.Re1 wins.

7.Bxd5+ Kf8

8.Bxc4 Qe1?

A mistake in a situation which is hopeless.

9.Nxg6+WINS

Black loses his new Queen.

Nimzowitsch and Larsen never met. The great theortician died the same year as Larsen was born but he would have been proud of this ending.
