Winawer Variation, Poisoned Pawn Variation

With 7...Qc7 Black leaves g7 to its fate and hits c3 and e5 instead. The usual 8. Qxg7 Rg8 9. Qxh7 cxd4 brings mutual weaknesses: White gains a passed h-pawn and kingside play, while Black breaks up the center and, with the kingside gone, typically castles long into the open b-file. Ten moves in, White chooses between 10. Ne2 (the Main Line) and 10. Kd1 (the Paoli Variation). 8. Bd3 declines the pawn. The engine gives White a slight edge.
