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, Gerard O'Reilly, Henryk Kalafut and Alexander Voyna.

LAST WEEK, POSITION 311

Vladimir Petrov, (1907-1944).

Latvian Grandmaster. Latvia's strongest player in the 1930s. His best result was at Kemeri in 1937, coming equal first with Flohr and Reshevesky ahead of Alekhine, Keres and Fine. During the War years Petrov played in a number of Soviet events and then disappeared from the scene. It was only many years later that his true fate was discovered. He had become a victim of political terror and had died in the Gulag. 

Petrov vs Grau

Buenos Aires, 1939

White to play and WIN

FORSYTH NOTATION

:1rq1k3/Rp1n4/1Pp1p1pp/N1Pp1p2/3P1P2/4P3/Q5PP/6K1 w - - 0 1:

Black has a very cramped position but he has managed to guard the queenside against invasion. The idea of Nxb7-Rxb7-Qa7 forcing the b-pawn home doesn't work because the b8 square is covered by the Black Knight. White now starts operations on the other wing with the plan to force the defending Knight out of position so that it cannot return to it's defensive post at d7. White can then mount a successful breakthrough on the queen's wing. The ending is very instructive and shows the brilliant talent of this ill-fated and forgotten player.

1.Qf2! ...

1.Nxb7? is premature because the Black Knight is defending the b8 square: 1...Rxb7 2.Rxb7 Qxb7 3.Qa7 Black can safely play 3...Qb8. White cannot make any progress.

1... Nf6

1...Kf7? 2.Qh4 h5 3.Nxb7! Rxb7 4.Rxb7 Qxb7 5.Qd8! winning.

2.Qh4 Ng8

The Knight is now displaced and White's push of the g-pawn, g4, g5 makes it impossible for the return of the piece to d7.

3.g4! Kf7

3...fxg4 4.Qxg4 Kf7 5.Qe2! Ne7! 6.Qa2 e5 7.fxe5 Kg7 8.Qe2! +-;

4.g5! h5

4...hxg5? 5.Qh7+ Kf6 6.Qh8+ Kf7 7.Nxb7! Rxb7 8.Rxb7+Qxb7 9.Qh7+ wins the queen by means of a skewer;

5.Qf2! Ke8

6.Qa2 Ne7

The Knight sacrifice is now possible. If the defending Knight was at d7 the b8 square would be covered and Black could hold on for a draw but resistance is now futile. The passed b-pawn can only be stopped from promoting at the cost of the Queen.

7.Nxb7! Rxb7

8.Rxb7 Qxb7

9.Qa7! Resigns.

 Gens Una Sumus.
Antonio Senatore, Henryk Kalafut and Alexander Voyna win in November.
