I just completed a 100-game blitz match between Gothmog 0.4.7 and Crafty 19.9
(yes, I know it is not the most recent version). In one of the games, the
following position arised:
[D]r2qr3/4bpkp/p2p2pN/1p1P4/2pNP3/1b5P/1P1Q1PP1/R3R1K1 w - -
Here, Gothmog surprised me (and Crafty) by playing the knight sac Nxf7!?. It
plays this after only 7 plies and 1 second, almost certainly as a speculative
sac, but still keeps it with a +1 score after 20 minutes and 16 plies. In
the game, Gothmog quickly got a winning attack after 24. Nxf7 Kxf7 25. Ne6 Qc8
26. Qh6 Bf8 27. Qxh7+ Kf6 28. Re3.
Which other engines like Nxf7? Is the sac correct?
Another cool game from the match was the following, which is probably
not good, but amused me because of its "19th century look". It was played
in Gothmog's new favorite opening, the King's gambit:
