Man vs Machine Bonn, Germany (4), 01.12.2006
1.e4 e5 2.Nf3 Nf6 3.d4. Fritz is avoiding the main line with 3.Nxe5. 3...Nxe4 4.Bd3 d5 5.Nxe5 Nd7 6.Nxd7 Bxd7 7.0-0 Bd6 8.Qh5 Qf6 9.Nc3 Qxd4 10.Nxd5 Bc6. So far the game has followed a 1990 encounter Kliesch,B-Wolf,W, which ended in a 49-move draw. 11.Ne3. Fritz deviates. 11...g6 12.Qh3 Ng5 13.Qg4 Qf4 14.Qxf4 Bxf4 15.Nc4

15...Ne6 16.Bxf4 Nxf4 17.Rfe1+ Kf8 18.Bf1 Bb5 19.a4 Ba6 20.b4 Bxc4 21.Bxc4 Rd8 22.Re4.

White has a clear advantage in development. Things are not looking good for Kramnik. 22...Nh5 23.Rae1 Rd7 24.h3 Ng7 25.Re5 Nf5 26.Bb5 c6 27.Bd3 Nd6 28.g4 Kg7 29.f4 Rhd8 30.Kg2 Nc8.

Kramnik has played well to spoil the computer's chances, and continues to try to simplify the position. 31.a5 Rd4 32.R5e4 Kf8 33.Kf3 h6 34.Rxd4 Rxd4 35.Re4 Rd6 36.Ke3 g5 37.Rd4 Ke7 38.c4 Rxd4 39.Kxd4 gxf4 40.Ke4 Kf6 41.Kxf4 Ne7 42.Be4 b6 43.c5 bxc5 44.bxc5 Ng6+ 45.Ke3 Ne7 46.Kd4 Ke6 47.Bf3 f5 48.Bd1 Kf6 49.Bc2 fxg4 50.hxg4 Ke6.

With Deep Fritz attacking, Kramnik has managed to set up a fortress which cannot be penetrated. He will simply shuffle his king between f6 and e6, and White can make no further progress. 51.Bb1 Kf6 52.Be4 Ke6 53.Bh1 Kf6 54.Bf3 Ke6 ½-½ [Click to replay]
