White has several threats, but black manages to >defend against them. Any winning line for white after Kg8? like dan said, 3.Qc2 should win - there is no concrete line i would quote, but white is simply winning due to the many weaknesses in the black camp (a5/d6/f6), the rook is worth nothing. the engines will show positive scores for white after Qc2 quickly. >>>2rqr1k1/1p1bbppp/p3p3/n7/3P2Q1/2PB1N2/P4PPP/R1B1R1K1 w - - bm Bxh7+; id >>>"ECM.673"; >>1.Bxh7+ Kxh7 2.
