Nanjing R04: Bacrot beats Anand, Carlsen leads

10/23/2010 – After a very nice win yesterday World Champion Viswanathan Anand today suffered a painful defeat when he apparently misjudged an endgame of four pawns vs bishop and two pawns. The winner: French GM Etienne Bacrot, who is now in place two on the table. Anand, it turns out, could have saved the "wrong-colored bishop" endgame, as our resident expert Dr Karsten Müller shows.

The wrong outside pawn. Normally an extra piece will win fairly easily in an endgame, but that may not be the case if the attacker has very few pawns. If one of them is, in addition, a "/portals/all/_for_legal_reasons.jpg" then it can easily become impossible.

42...g5? After this the path of the black king to the kingside is blocked and the extra pawn can repeatedly use the sharp endgame weapon of zugzwang to win the day. 42...e5+ on the other hand keeps all options open and draws: 43.Kd5








(43.Ke3 g5 44.Ba6 (44.h3 e4 45.Kd4 g4 46.hxg4 fxg4 47.Bxg4 Kg5 48.Bh3 Kf4= and the black counterplay is sufficient to draw.) 44...f4+ 45.Kf3 e4+ 46.Kxe4 h3 47.gxh3 Kg7=) 43...e4 (43...h3? would be premature: 44.g3 f4 45.g4 (45.Ke4 Kg5 46.Bf3+- wins prosaically) 45...Kg5 46.Kxe5 Kh4!?








Black sets a clever little stalemate trap, which can, however, be circumvented. 47.Bf3 (47.Kxf4? g5+ 48.Kf5 patt) 47...g5 48.Bd1 f3 49.Ke4 f2 (49...Kxg4 50.Bxf3+ Kh4 51.Be2 g4 52.Kf4 Kh5 53.Bb5+-) 50.Be2 f1Q 51.Bxf1 Kxg4 52.Bb5 Kh5 53.Be8+ Kh6 54.Kf5








and in this constellation White can win in spite of the wrong colored bishop: 54...Kh7 55.Kf6 Kh8 56.Bg6 Kg8 57.Bd3 Kh8 58.Kf7 g4 59.Be4 g3 60.hxg3+-) 44.Bd1 Kg5!








The king uses this route to either convert the white g-pawn into a wrong-colored h-pawn, or to eliminate it altogether: 45.Ke5 f4 46.Kxe4 (Even after 46.h3 f3 47.gxf3 exf3 48.Bxf3 Kh6 White cannot gain anything from his outside pawn, e.g. 49.Kf6 Kh7 50.Bd5 Kh8=) 46...h3 47.g3 (47.gxh3 Kh4 48.Bg4 f3 49.Kxf3 g5 50.Bf5 Kh5=) 47...fxg3 48.hxg3 h2 49.Bf3 h1Q 50.Bxh1 Kg4=.

43.Ba6! g4








Now the white king can cut off Black's path after 43...e5+ 44.Kd5 e4 45.Bf1 g4 rechtzeitig den Weg abschneiden: 46.Kd4 Kg5 47.Ke3 h3 48.g3 f4+ 49.gxf4+ Kf5 50.Ba6 g3 51.Bc8+ Kf6 52.Bxh3 gxh2 53.Bg2+-. 44.Bb7! e5+. 44...f4 45.Ke4 f3 46.g3+-] 45.Kd5! f4 [45...e4 46.Kd4 h3 47.g3 f4 48.Kxe4+-] 46.Ke4 and Anand resigned because in the end all of his pawns will fall, e.g. [46.Ke4 h3 47.g3 fxg3 (47...f3 48.Bc8 f2 49.Ba6 Ke6 50.Ke3+-) 48.hxg3 h2 49.Ke3+-. 1-0.
