"The program has become more human in a different way. It now has extensive chess knowledge and a human evaluation structure, ensuring that it finds good moves and interesting ideas where there are no direct tactics to guide it. You will appreciate the value of this when you analyze with the program. Fritz 9 thinks and plans like a human, while retaining the tactical ferocity of the world’s top chess engine" www.chessbase.com You don´t believe this? You think that´s a load of crap? You are wrong, please look at the following examples and decide yourself: Example 1: [D]rnbqkb1r/ppp2ppp/3p1n2/4P3/4P3/2N5/PPP2PPP/R1BQKBNR b KQkq - 0 4 Analysis by Fritz 9: 4...Sfd7 5.exd6 Lxd6 6.Sb5 Lb4+ 7.c3 Lc5 8.Lg5 f6 9.Dh5+ ± (0.91) Depth: 7/21 00:00:00 53kN 4...Sfd7 5.Sd5 dxe5 6.Lg5 f6 7.Lh6 Sc6 8.Dh5+ g6 ± (0.76) Depth: 8/27 00:00:00 255kN 4...Sfd7 5.exd6 Lxd6 6.Sb5 Le7 7.Lf4 Sa6 8.Dd5 Lb4+ 9.c3 Lc5 ± (0.94) Depth: 9/27 00:00:00 504kN 4...Sfd7 5.exd6 Lxd6 6.Sb5 Lb4+ 7.c3 La5 8.Dd5 0-0 9.Lg5 ± (1.07) Depth: 10/29 00:00:01 1063kN 4...Sfd7 5.exd6 Lxd6 6.Sb5 Sf6 7.Lg5 0-0 8.Sf3 Sc6 9.Sxd6 cxd6 10.c3 De8 11.Lxf6 Dxe4+ ± (1.14) Depth: 11/32 00:00:03 3319kN 4...Sfd7 5.exd6 Lxd6 6.Sb5 De7 7.Sxd6+ cxd6 8.Ld3 0-0 9.Se2 Sc5 10.0-0 Sxe4 11.Te1 ± (1.02) Depth: 12/37 00:00:10 9001kN 4...Sfd7 5.exd6 Lxd6 6.Le3 0-0 7.Dd2 De7 8.0-0-0 Td8 9.Lf4 Se5 10.Sd5 De8 ± (1.16) Depth: 13/34 00:00:24 23816kN 4...Sfd7 5.exd6 Lxd6 6.Le3 0-0 7.Dd2 De7 8.0-0-0 Sc6 9.Lg5 De6 10.Sf3 Sde5 11.Sd4 Dg4 ± (1.08) Depth: 14/41 00:01:00 60691kN 4...Sfd7 5.exd6 Lxd6 6.Le3 De7 7.Dd2 Sf6 8.Ld3 0-0 9.Sf3 Sc6 ± (1.13) Depth: 15/39 00:02:29 156351kN 4...Nfd7! A Master would not even think about the materialistic 4...dxe5? which is the typical computer move in this position. Instead true masters of the game willingly give up pawns in exchange for a better position. Unlike other engines Fritz 9 understands the importance of development and King safety. Example 2: De Andrade,W - Lima,D, IX Taca BCX Brasiliat BRA 2005 [D]rnbqk2r/1pp2pb1/p2p1npp/4P3/4P1P1/2N1B2P/PPP1BP2/R2QK1NR b KQkq - 0 1 Analysis by Fritz 9: 8...Nh7 9.exd6 Ng5 10.Qd3 Qxd6 11.0-0-0 Qxd3 12.Rxd3 +- (1.80) Depth: 7/24 00:00:00 113kN 8...Nh7 9.exd6 Be6 10.Qd3 Qxd6 11.0-0-0 Qxd3 12.Rxd3 Ng5 13.Nf3 +- (1.94) Depth: 8/28 00:00:00 553kN 8...Ng8! +- (1.93) Depth: 8/28 00:00:00 607kN 8...Ng8 9.f4 Ne7 10.Qd2 Nbc6 11.exd6 Qxd6 12.0-0-0 Qxd2+ 13.Rxd2 Bxc3 +- (1.88) Depth: 8/30 00:00:00 714kN 8...Ng8 9.exd6 Bxc3+ 10.bxc3 cxd6 11.Nf3 Nf6 12.Bd3 Be6 13.0-0 +- (1.91) Depth: 9/29 00:00:01 1224kN 8...Ng8 9.exd6 Bxc3+ 10.bxc3 cxd6 11.Bf4 Qf6 12.Qd2 Nc6 13.0-0-0 Qe6 14.Qd5 Nf6 +- (1.87) Depth: 10/34 00:00:02 2349kN 8...Ng8 9.f4 Nc6 10.Nf3 h5 11.g5 dxe5 12.Qxd8+ Nxd8 13.Nd5 +- (1.99) Depth: 11/36 00:00:07 6541kN 8...Nh7! +- (1.98) Depth: 11/36 00:00:08 7264kN 8...Nh7 9.Qd2 Bxe5 10.0-0-0 Nc6 11.Nf3 Be6 12.Nxe5 dxe5 13.Qe1 Qh4 14.f4 Qxe1 +- (1.86) Depth: 11/36 00:00:09 8589kN 8...Nh7 9.Qd2 Bxe5 10.Nf3 Bxc3 11.Qxc3 Nf6 12.Bd4 Nbd7 13.0-0-0 c6 14.Qe3 Qe7 15.e5 dxe5 16.Nxe5 +- (1.95) Depth: 12/37 00:00:15 14390kN 8...Ng8! +- (1.95) Depth: 12/37 00:00:19 18244kN 8...Ng8 9.exd6 Bxc3+ 10.bxc3 cxd6 11.Bf4 Nf6 12.Bxd6 Be6 13.Bf3 Nc6 14.Ne2 Nd7 15.0-0 +- (1.86) Depth: 13/47 00:00:40 39512kN 8...Ng8 9.f4 Nc6 10.Nf3 Nge7 11.exd6 Bxc3+ 12.bxc3 cxd6 13.Qd3 Qa5 14.Nd4 0-0 15.0-0 +- (1.96) Depth: 14/44 00:01:27 86010kN 8...Nh7! +- (1.96) Depth: 14/44 00:01:43 102280kN 8...Nh7 9.Qd2 Bxe5 10.Nf3 Bxc3 11.Qxc3 Nf6 12.Bd4 Nbd7 13.0-0-0 +- (1.96) Depth: 14/44 00:01:59 118747kN 8...Nh7!!. Fritz 9 thinks and plans like a GM. There is an old saying "A knight on the rim is dim", however a human master also has to know about the exceptions to the rules.

Again Fritz 9 avoids a typical computer mistake. 6...e5? would have been a very bad idea due to the winning move 7.Bg5!: Analysis by Fritz 9: 7.Bg5 Nf6 8.Bc4 Qa5+ 9.Bd2 Qb6 10.N1c3 Be6 ± (0.99) Depth: 7/24 00:00:00 57kN 7.Bg5! ± (1.27) Depth: 8/27 00:00:00 181kN 7.Bg5-- ± (0.99) Depth: 9/28 00:00:00 463kN 7.Bg5 Nf6 8.Bc4 ± (0.99) Depth: 9/33 00:00:00 565kN 7.Bg5 Nf6 8.Bc4 Be6 9.Bd5 Qb6 10.N1c3 Bg4 11.Bxc6+ Qxc6 12.f3 ± (0.97) Depth: 10/32 00:00:01 1414kN 7.Bg5 Nf6 8.Bc4 Be6 9.Nd2 a6 10.Nc3 Be7 11.0-0 0-0 12.Qf3 ± (1.01) Depth: 11/35 00:00:03 3391kN 7.Bg5 Nf6 8.Bc4 Be6 9.Nd2 a6 10.Nc3 Be7 11.0-0 0-0 12.Bxf6 Bxf6 13.Qh5 ± (0.87) Depth: 12/36 00:00:09 8469kN 7.Bg5 Nf6 8.Bc4 Be6 9.Nd2 a6 10.Bxf6 gxf6 11.Bxe6 fxe6 12.Qh5+ Kd7 13.Nc3 Kc7 14.0-0-0 ± (0.86) Depth: 13/40 00:00:21 21113kN 7.Bg5 Nf6 8.Bc4 Be6 9.Bxf6 gxf6 10.N1a3 a6 11.Nc3 Rg8 12.0-0 Rg6 13.Qh5 Rh6 14.Qf3 ± (0.76) Depth: 14/41 00:00:53 55282kN 7.Bg5 Nf6 8.Bc4 Be6 9.Bxf6 gxf6 10.N1a3 Qa5+ 11.c3 0-0-0 12.Qb3 Kb8 13.Bxe6 fxe6 14.Qxe6 ± (0.75) Depth: 15/44 00:02:18 146969kN The renowned tester Kurt Utzinger has sent us some typical games played by the new Fritz 9 in order to demonstrate the new human-like style: [Event "Fri9_Shr9 Ath 1.3/64 40'/40"] [Site "Zurich"] [Date "2005.09.28"] [Round "8"] [White "Shredder 9"] [Black "Fritz 9"] [Result "1-0"] [ECO "E91"] [PlyCount "65"] [EventDate "2005.??.??"] 1. d4 Nf6 2. c4 g6 3.
