Kramnik vs Deep Fritz: Computer wins match by 4:2

12/5/2006 – World champion Vladimir Kramnik played a very spirited final game in his match against Deep Fritz in Bonn, Germany. It was a very double-edged encounter, with the computer playing some highly unusual and deep ideas to gain the upper hand and win the game on move 47. The final score was 4:2. Annotated game and big photo report.

Game six

Deep Fritz 10 - Kramnik,Vladimir (2750) [B86]
Man vs Machine Bonn, Germany (6), 05.12.2006

1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.Bc4 e6 7.0-0 Be7 8.Bb3 Qc7 9.Re1

9...Nc6.

This position has occurred at least nine time in international tournament chess, with the moves played being 10.Bg5 (four times), 10.a3, 10.Nxc6, 10.Qd3, 10.Be3 and 10.f4. The move and manoeuvre Deep Fritz plays has certainly never been seen before. 10.Re3 0-0 11.Rg3 Kh8 12.Nxc6 bxc6 13.Qe2 a5 14.Bg5 Ba6 15.Qf3 Rab8 16.Re1 c5 17.Bf4 Qb7 18.Bc1.

The manoeuvre Bc1-g5-f4-c1 (with Ra1-e1 incerted) caused some amusement in the commentary boxes in Bonn, but as with Rf1-e1-e3-g3 the GMs slowly started to see meaning in the "madness". 18...Ng8 19.Nb1. Amazing: a mirrored knight retreat on both sides. Once again the GMs doing live international commentary broadcasts were surprised and amused by the computer moves, but slowly started to find reasons for it. 19...Bf6 20.c3 g6. The commentators who had given Black a substantial advantage (while Deep Fritz persistantly saw White in the lead) now slowly started to have doubts about Kramnik's position. 21.Na3. This was not the move the GMs anticipated (...Nd2 was the reason given for 19.Nb1). Deep Fritz is still playing moves that take a while for humans to appreciate. 21...Qc6 22.Rh3 Bg7 23.Qg3 a4 24.Bc2 Rb6.

Kramnik said later that immediately after he had played the move 24...Rb6 he had seen the computer's reply: 25.e5! dxe5 26.Rxe5 Nf6 27.Qh4 Qb7 28.Re1 h5 29.Rf3 Nh7 30.Qxa4 Qc6

White is now a pawn up and firmly on the path to victory. 31.Qxc6 Rxc6 32.Ba4 Rb6 33.b3 Kg8 34.c4 Rd8 35.Nb5 Bb7 36.Rfe3 Bh6 37.Re5 Bxc1 38.Rxc1 Rc6 39.Nc3 Rc7 40.Bb5 Nf8 41.Na4 Rdc8 42.Rd1 Kg7 43.Rd6 f6 44.Re2 e5 45.Red2 g5 46.Nb6 Rb8 47.a4 and Black resigned.

Fritz has played this game very impressively, as all the GMs and Vladimir Kramnik himself have admitted. 1-0. [Click to replay]
