It's the only move Bright 0.4a looks at. I think you might have this move programmed into the latest Bright book.

White does not win after Bxt6.

At move 15, Black can play Ne5 and draw. The actual move played in that game (Kh8) is a stinker.

[d]r1bq2k1/pppp2N1/6Q1/8/1bn1P3/8/P1PP2PP/RN4K1 b

Ne5 Qg3 Kh7 Nf5 Qf6 is the line I mean.

I also am curious what your find is against 12...d5 (instead of 12..Rxf6)

rybka is also quite unconvinced --

[d]r1bqk2r/ppppn1pp/5B2/n7/1bB1PN2/8/P1PP2PP/RN1QK2R b KQkq - 0 8

8... Rf8 9. Bg5 Rxf4 10. Bxf4 Ng6 11. Qh5 Nxc4 12. Bg5 Be7 13. Bxe7 Qxe7 14.
O-O c6 15. Qxh7 Nf8 16. Qh5+ g6 17. Qh6 [-. 16, d20, rybka 3]

the 9. Nh5 line was discarded for white by rybka at d17 in favor of 0-0, then Bg5 at depth 20.

[AdminX]

Note that 9. 0-0! of Deep Fritz 11. Looks just as strong as Andrew Martins Nh5.
