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 Jim Monaghan, Gerard O'Reilly, Antonio Senatore and Henryk Kalafut.
THIS WEEK

POSITION 265

White to play and WIN

FORSYTH NOTATION:2n5/7B/6p1/3K3k/7N/8/5P2/8:
LAST WEEK, POSITION 264

Tigran Petrosian, (1929 -1984).

World Champion 1963-69. Soviet Grandmaster. In the early 1950's, Petrosian emerged from the ranks of Soviet Masters to become a leading player and a Candidate for the world championship. It was on the the island of Curacao, in the Caribbean, where he had his greatest triumph, taking first place in the 5th Candidates' Tournament (+8 =9) and so becoming Botvinnik's challenger for the World Championship.

  Fischer vs Petrosian

Curacao, 1962

Black to play and WIN

FORSYTH NOTATION:5rk1/p3n1p1/B3p2p/3bP3/P2N4/8/6PP/4R1K1:

Bobby Fischer got off to a poor start at Curacao and never was in contention. He had had a miserable record against Petrosian which wasn't about to change. It was only a decade later that Fischer began to outscore him.

White will have great difficulty defending his e-pawn so he puts his hope in the strength of his a-pawn. Petrosian is brilliant in this ending and Fischer's idea only just fails. Notice how important it is to get the Black King over to the queenside to counter White's threat.

4.a5 Nxe5

5.a6?! ...

White hopes to fix the "a7" pawn as a weakness but by seeking the exchange of the Rooks, he could have made the win technically more difficult: 5.Rf1 Rxf1+ 6.Kxf1 Nc4 7.Nb5 Nxa5 8.Nxa7 Nc4 -+;

5... Rg4!
