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, Federico Giallombardo, Jim Monaghan, Jon Palmer and Alexander Voyna.

Lev Polugayevsky, (1934-1995).

White to Play and WIN

FORSYTH NOTATION

:3R4/p1r2kp1/1p3p2/1P2p2P/PB6/6P1/1n2PPK1/8 w - - 0 1:

White has an extra pawn on the kingside and the Black King has only one free square. Can White by the offer of his a-pawn entice the enemy monarch into a mating net ? The following main line shows the moves played in the game:

1.Bd6! Rb7

1...Rc2 2.Ra8 Ke6 3.Ba3 Nc4 4.Bf8 Kf7 5.Bb4 Rxe2 6.Rxa7+ Kg8 7.Rc7 Re4 8.Bc3 Na3 9.a5 Nxb5 10.Rc8+ Kh7 11.axb6 Nxc3 12.b7 White wins.

1...Rc4 2.a5 Rd4 3.Bc7 Rxd8 4.Bxd8 bxa5 (4...Nc4 5.Bxb6! with a win) 5.Bxa5 5.Bxa5 Na4 6.Bb4 Nb6 7.Bc5 Nc8 8.g4 Ke6 9.Kf3 Kf7 10.Ke4 White wins.

1...Rc3!? 2.Rd7+! Ke6 3.Rxg7 Kxd6 4.h6 Rc8 5.h7 Rh8 6.Rxa7 and according to analysis by Polugayevsky White is winning.

2.e4! Nxa4?!

Black gets back his material but White has a strong attack against the King. A better move is: 2...Ke6! 3.f4! exf4 4.gxf4 f5 5.Ba3!! Nc4 6.Re8+ Kf7 7.Rf8+ Ke6 8.exf5+ Kd5 9.Bb4 Nb2 10.Bc3 Nxa4 11.Be5 Nc5 12.Kf3 Nb3 13.Ke3 Kc4 14.Rg8 +-;

3.f4! exf4

4.gxf4 g5

A desperate attempt to escape the mating net which is surrounding his King.

4...Nc3!? 5.f5! Re7 6.Bxe7 Kxe7 7.Rb8 +-;

5.e5! gxf4

5...Ke6 6.Re8+ Kf5 7.fxg5 Kxg5 8.e6! Nc3 9.e7 Rxe7 10.Bxe7 White wins or 5...fxe5 6.fxg5 e4 7.Rf8+ Kg7 8.Rc8 Nc5 9.Be5+ Kf7 10.g6+ Ke6 11.h6! and White wins.

6.h6! Ke6

6...Kg6 7.e6! Rh7 8.e7 Rxe7 9.Bxe7 wins;

7.Re8+! Kf5

7...Kd5 8.Be7! fxe5 9.h7 with a win.

8.e6 Resigned

The two passed pawns have become monsters. Black's task is hopeless. 

Gens Una Sumas. 
Gerard O' Reilly wins in May.
