Hi Martin >I think Nxf7 is winning, although Ruffian didn't really see the win: > >1.Nxh7 Kxh7 2.Qh5+ Kg8 3.Bxg6 Qe7 4.Re3 Bxd4 5.Rh3 Bxf2+ 6.Kh1 Qg7 (pv at >depth 15.01) >and now (instead of Bh7+ with a draw) Bh6! Qe5 Qg4! wins. Even worse! Ruffian is not seeing the win even with the right line. Here is ruffians analysis in your given position.

Now the question is why Ruffian considers the position as 0.00 in its original analysis. Bye Ingo
