The next annotated game was published at the chess column of the Spanish newspaper 'El Pais' on December 24, and it was written by chess journalist and Fide Master Leontxo Garcia. Yesterday I decided to post this message in this forum and I have translated it into English. I hope I didn't commit too many mistakes in this language. Regards. MB --- [D] 6k1/6b1/1B1p2qp/3Pp1p1/2r1p3/3n2P1/P2QB2P/R5K1 w - - 0 27 Position after 26...Rxc4 *Silicon is silly* White: Gelfand. Black: Sutovski. King's Indian Defence. Pamplona, December 22, 2004. In the opening round Israeli Boris Gelfand manages very well a position that computers don't understand yet. 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Be2 0-0 6.Nf3 e5 7.Be3 h6 8.0-0 Ng4 9.Bc1 Nd7 10.d5 Ngf6 11.Be3 Ng4 12.Bd2 f5 13.g3 fxe4 14.Nh4 g5 15.Ng6 Nxf2 16.Rxf2 Rxf2 17.Kxf2 Qf6+ 18.Kg1 Qxg6 19.Nb5 Nc5 20.Nxc7 Rb8 21.Be3 b6 Black's advantange, a pawn, is very little important: the bishop on g7 is almost useless and the pawns on a7, b6 and d6 are weak. 22.Nb5 Nd3?! As the reader is going to understand very soon, it was better 22...a6 23.Nxa7 Nxb2 24.Qd2 Nd3 25.Nxc8 Rxc8 26.Bxb6 Rxc4 (diagram) Gelfand has got a clear advantage, thanks to his passed pawn on a2. But chess programs don't appreciate it, not even after a long calculation time. It is due to the so called 'horizon effect': Silicon is uncapable of understanding that the little pawn on a2 is a potential queen, something that any chess player of certain skill sees it in tenths of second. 27.a4! Qe8 28.a5! Ra4 The computer shows that 28...Qb5 is advantageous for Black, without noticing that after 29.Be3 Qxd5 30.a6 Rc8 31.a7 Qa8 32.Bg4 Rf8 33.Be6+ Kh8 34.Qa2, with the threat of Bd5, 34...Nb4 35.Qb3, Black must resign. 29.Qd1 Rxa1 30.Qxa1 Qb5 31.Be3 Qb3 32.Bd1! The last trick was 32.a6 Nf4 33.a7 Qxe3+ 34.Kh1 Qxe2 35.a8=Q+ Kh7 36.gxf4, and now both 36...Qf3+ and 36...exf4 are drawn. 32...Qb4 33.Bg4 Nc5 34.a6! Nxa6 35.Qxa6 Qe1+ 36.Kg2 Qxe3 37.Be6+ Kh7 38.Bf5+ Kg8 39.Qc8+ Sutovski resigned in view of an imminent mate.
