[D] rnbqk2r/pp1pbppp/2p5/8/2BP1p2/2P5/P1P1N1PP/R1BQ1RK1 w kq - 0 9

bm Bxf7+

This is the whole game, which is quite remarkable:

[Event "ICC 15 3"]
[Site "Internet Chess Club"]
[Date "2011.10.14"]
[Round "?"]
[White "Orcrist"]
[Black "crafty"]
[Result "1-0"]
[ECO "C33"]
[WhiteElo "2981"]
[BlackElo "2643"]
[PlyCount "63"]
[EventDate "2011.??.??"]
[TimeControl "900+3"]

1. e4 e5 2. f4 exf4 3. Bc4 Nf6 4. Nc3 c6 5. d4 Bb4 6. Nge2 Nxe4 7. O-O Nxc3 8.
bxc3 Be7 9. Bxf7+ Kxf7 10. Nxf4 Kg8 11. Nh5 d5 12. Qf3 Qe8 13. Bh6 Qg6 14. Bxg7
Nd7 15. Rae1 Bd6 16. c4 dxc4 17. Qe2 Ne5 18. Bxe5 Bg4 19. Qxc4+ Be6 20. Qe2 Bb4
21. Nf6+ Kg7 22. Rb1 Rhf8 23. Rxb4 b6 24. d5 Bf5 25. Rxf5 Qxf5 26. Ne8+ Kg8 27.
Rg4+ Qg6 28. Rxg6+ hxg6 29. Qg4 Rf7 30. Qxg6+ Kf8 31. Nd6 Rf1+ 32. Kxf1 1-0

As far as I can tell, 6. Nge2 is a novelty (usual is 6. e5).

That is even more amazing - a forced mate! - but it seems this is too deep for many programs.

It is indeed an amazing move - certainly not trivial, even for today's monsters. Maybe it's one for your test set?

Bright does well to find a mate in less than one minute on my Intel i7 2.2 GHz

This is the whole game, which is quite remarkable:

[Event "ICC 15 3"]
[Site "Internet Chess Club"]
[Date "2011.10.14"]
[Round "?"]
[White "Orcrist"]
[Black "crafty"]
[Result "1-0"]
[ECO "C33"]

As far as I can tell, 6. Nge2 is a novelty (usual is 6. e5).
