Absolutely, the Najdorf is a better anti-computer opening ... except Adams doesn't know it and doesn't play it. Just look at the game below where he was beaten by someone rated 370 points lower: Ahn,M (2290) - Adams,M (2660) [B93] EUCup Gr1 Clichy (1), 1995 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 6.f4 Qc7 7.Qf3 g6 8.Bd3 Bg7 9.Nde2 Nbd7 10.Be3 0-0 11.0-0 Nc5 12.Bd4 Bg4 13.Qf2 Bxe2 14.Qxe2 e5 15.Be3 Rac8 16.f5 b5 17.Bg5 Ncd7 18.a3 h6 19.Bh4 Qc6 20.Rad1 Nb6 21.Kh1 Qb7 22.Rd2 g5 23.Bf2 Rfe8 24.Qf3 Rcd8 25.Rfd1 Qc7 26.Qe3 Nc8 27.Be2 Qc6 28.h4 g4 29.Nd5 h5 30.Nxf6+ Bxf6 31.Qh6 Bg7 32.Qxh5 Qxe4 33.Bd3 Qb7 34.f6 1-0 Now imagine what Hydra would do. -Robin > >Michael > > > in a blitz game no less?
