SEE 0.4.2 is my engine. This game was played on a p3 500, 256 megs ram. TC was
10 10.
SEE 0.4.2 - DrunkenMaster [B67]
15.10.2003

1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 d6 6.Bg5 e6 7.Qd2 a6 8.0-0-0 Bd7
9.f4 b5 10.Bxf6 Qxf6 11.e5 dxe5 12.Ndxb5 0-0-0 13.fxe5 Qxe5 14.Nd6+ Bxd6 white
is clearly winning, but my engine is horrible at endgames, and it managed to pop
the pawn back later...

15.Bxa6+ Kb8 16.Qxd6+ Qxd6 17.Rxd6 e5 18.h4 typical sort of 'my computer move',
endgame eval really needs some work Nd4 19.b4 Bf5 20.Nb5 Nxb5 21.Rxd8+ Rxd8
22.Bxb5 Rd4 23.c3 Rg4
[D]1k6/5ppp/8/1B2pb2/1P4rP/2P5/P5P1/2K4R w - -

ok, heres the position i'm mainly interested in. Does black win this? or can
white hold on for a draw. White played a5 with a -0.16 score. but can black win?
heres the rest of the game anyway 27.a5 f6 28.h5 f5 29.b5 Ra2 30.Rd1 Ra1+ 31.Kc2
Rxa5 32.Rd5 Ra2+ 33.Kd3 e4+ 34.Ke3 g6 35.hxg6 hxg6 36.Rd6 Rg2 37.c4 Rc2 38.Rb6+
Kc7 39.Rxg6 Rxc4 40.Kf4 Rc5 41.b6+ Kb7 42.Rf6 Rb5 43.Rg6 Ka6 44.Rf6 Rd5 45.Ke3
Rc5 46.Kf4 Kb7 47.Rh6 Ra5 48.Rf6 Rc5 49.Rh6 Rc2 50.Kxf5 e3 51.Re6 e2 52.Kf4 e1Q
53.Rxe1 Kxb6 ½-½


interesting to see what other engines (operators) think.
