Here is a recent game played by Arasan against BK-Chess. The finger
notes say this is Shredder on a fast Pentium.

1-0 {ArasanX resigns}
The winning attack here is quite human-like: White ignores
material and goes for the kill. I was impressed, especially
given that this was a fast blitz game.
The first interesting point is the sac on move 15:
[D] r1b2rk1/ppp2ppp/3p1n2/2q1n3/3N4/2N1P1P1/P1PP2BP/R2Q1RK1 w - -
Crafty prefers Nb3, even after 10 minutes and over
250 million positions.
17. Nh5+ is also hard for many programs to find:
[D] r1b2r2/pp3pkp/1q1p1N2/2p1n3/3N4/4P1P1/P1PP2BP/R4QK1 w - c6
Crafty selects Nh5+ after 3 1/2 minutes on a Pentium III/733,
although the score is still only 0.
18. Qf6+ is also somewhat difficult, although this probably
wouldn't be hard for a human to play:
[D] r1b2r2/pp3p1p/1q1p3k/2p1n2N/3N4/4P1P1/P1PP2BP/R4QK1 w - -
Qf6+ takes Crafty 1:40 to find. Arasan doesn't find it at all
in over 5 minutes. Shredder played it in this game in
maybe 10 seconds (I don't have the exact time).
