 Then 4.gxh3 is a standard book draw, since White's bishop is of the "wrong color" from the rook pawns (i.e., it moves on the squares opposite in color to that of the pawns' queening square) and thus can never drive Black's king from the h8 corner.On other moves, Black will play 4...Bxg2!, again leaving White with a rook pawn and the wrong-colored bishop.Black implemented this idea in actual play in Carlsen–Aarland, Norwegian Championship final 2002.
