First, the (famous) game. Glucksberg - Najdorf, Warsaw 1935. 1.d4 d5 2.c4 e6 3.Nc3 c6 4.e3 f5 5.Nf3 Nf6 6.Bd3 Bd6 7.O-O O-O 8.Ne2 Nbd7 9.Ng5 Bxh2+ 10.Kh1 Ng4 11.f4 Qe8 12.g3 Qh5 13.Kg2 Bg1 14.Nxg1 Qh2+ 15.Kf3 e5 16.dxe5 Ndxe5+ 17.fxe5 Nxe5+ 18.Kf4 Ng6+ 19.Kf3 f4 20.exf4 Bg4+ 21.Kxg4 Ne5+ 22.fxe5 h5# Now for the questions: How long does it take for programs to... 1) decide to play 15...e5! 2) assess 15...e5! as about +4 for Black (roughly the score if White had played 21.Ke3 and dropped his queen. The interpolation of 16.cxd5 cxd5 doesn't substantially change matters.) 3) decide to play 13...Bg1! (it's better than ...Bxg3) 4) assess 13...Bg1! as about +2 for Black (up two pawns). Dave
