I am only using 350 MHz Hewlett Packard Pentium ll with 384 SDRam. Nalimov endgame turbo ( 4 discs) also additional downloaded Tablebases from the Hyatt FTP site. I have no idea what programs I was playing against, as some of the games were on the Yahoo chess site. However, I do have one of the losses to show you, the other being a draw. The loss was with it's king uncastled and what to me looked like horrible wing attack, leaving the board wide open for infiltration into it's own king position. Here are the games: Deep Fritz 7 - Unknown [E87] Blitz:5'+12" Eatontown, 13.09.2002 [Katz,Brian] 32MB, DeepFritz7.ctg, Pavilion 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.f3 0-0 6.Be3 e5 7.d5 Na6 8.Nb5 b6 9.a4 Bb7 10.a5 Nd7 11.h4 f5 12.h5 Bf6 13.Ne2 Bg5 14.Bxg5 Qxg5 15.hxg6 hxg6 16.exf5 Ndc5 17.g4 gxf5 18.Rh5 Qg6 19.Ng3 fxg4 20.fxg4 Bc8 21.Qd2 Rf4 22.Qh2 Nb4 23.Rh8+ Kg7 24.Rxc8 Nc2+ 25.Kd2 Nb3+ 26.Kd1 Ne3+ 27.Ke1 Rxc8 28.Nh5+ Kg8 29.Nxf4 exf4 30.Qh5 Qxh5 31.gxh5 Nxa1 32.Bh3 Rf8 33.a6 Nxc4 34.Kf2 Nxb2 35.Kf3 Nc4 36.Be6+ Kg7 37.Kf2 Nb3 38.Nxa7 Nc5 39.Nb5 Nxa6 40.Bg4 0-1 This next game was played on the ICC site against a Human master. It appears that black had better on move 38 that it played. Deep-Katzparov (2841) - diomedes (2490) [E33] ICC 5 12 Internet Chess Club, 10.09.2002 1.c4 Nf6 2.d4 e6 3.Nc3 Bb4 4.Qc2 Nc6 5.Nf3 d6 6.a3 Bxc3+ 7.Qxc3 Qe7 8.g3 e5 9.d5 Nd8 10.Bg2 0-0 11.0-0 a5 12.Bg5 h6 13.Be3 a4 14.Nd2 b6 15.f4 Ng4 16.h3 Nxe3 17.Qxe3 f6 18.Rf2 Bd7 19.f5 Nb7 20.Qf3 Nc5 21.Rb1 Rab8 22.Rff1 b5 23.b4 axb3 24.Nxb3 b4 25.axb4 Rxb4 26.Nxc5 26...dxc5 27.Qe4 Rfb8 28.Ra1 Qd6 29.e3 Qb6 30.Rfc1 Rb2 31.Kh1 Qb4 32.Rc2 Rb1+ 33.Rxb1 Qxb1+ 34.Kh2 Rb3 35.h4 Rxe3 36.Qxe3 Qxc2 37.Qxc5 Bxf5 38.Kh1 Be4 39.Bxe4 Qxe4+ 40.Kh2 Qe2+ 41.Kg1 Qd1+ 42.Kh2 Qc2+ 43.Kh3 Qf5+ 44.Kg2 Qd7 45.Qb5 Qd6 46.Qe8+ Qf8 47.Qc6 Qd6 48.Qe8+ Qf8 49.Qc6 Qd6 50.Qe8+ ½-½ This second game wasn't too bad, as you have to give credit to the Human opponent even though he faltered later in the game and only was able to get a draw. Many of the other games were engine tournament run on One computer, with permanent brain turned off. Deep-Fritz definately does not seem to play better than Fritz 7 when comparing the two engines with a single processor on one computer as Chessbase advertized. The engine tournaments were with 5/12 time controls, game 30, game 2, game 5. I don't have the game score of it's most recent pathetic loss. All replies welcome. Tell me what you think.
