This position is a draw, I cannot see anyway how can White win, for this reason
I don't think that 1.Bxh7 is a mistake at all because it is up to Black to find
the move 1.... g5+!!.  Hence, the question should be, which programs find 1. ...
g5+ after 1. Bxh7 to secure the draw?
There's no win for White if Black finds the correct move(s).  If I am wrong,
show me with a variation that White can win.
