The following diagram is from the game Polugayevsky vs E Torre London 1984
[D]rn1qr1k1/1p2bppp/p3p3/3pP3/P2P1B2/2RB1Q1P/1P3PP1/R5K1 w
Here white played 19.Bxh7+.This is found by Chessmaster 8000 after 2 hours and
38 minutes at 1800MHZ.Here is the info:
Time Score Positions Depth Moves
2:38:37 0.39 1828329861 13 Bxh7+ Kxh7 Qh5+ Kg8 Rg3 Bf8 Bg5 Qc8 Rc1
Nc6 Bf6 Nxd4 Rxc8 R(a)xc8 Qd1 Rc4 Bg5
Now the amazing thing is that Chessmaster 9000 never gets 19.Bxh7+ even at
16 plys and beyond.Here is how the actual game ended:19.Bxh7+ Kxh7 20.Qh5+ Kg8
21.Rg3 g6 22.Rxg6 fxg6 23.Qxg6+ Kh8 24.Qh6+ Kg8 25.Qxe6+ Kh8 26.Qh6+ Kg8 27.Qg6+
Kh8 28.Qh5+ Kg8 29.Bh6 Bf8 30.Qg6+ Kh8 31.Bxf8 Rxf8 32.Qh6+ Kg8 33.Ra3
{Black Resigns}
Perhaps CM9000 represents only a very minor improvement over CM8000.More testing
is required.Of course both are Extremely strong programs.
