What should be Black's next move? In this game, the last move made by white was Bg5 . Now it's black's turn. A software analysis shows that black is winning in this position with -2.51 evaluation. I am unable to spot the black's next best move ? Any kind of hint is appreciated !
This seems to be a bug in the chessboard's engine. If you look at the engine's main line, you'll see that it is bogus. After 11... h6, White will never sacrifice his bishop.
