PETROFF'S DEFENCE
Main line
Black's KKt counterattacked White's KP to simplify the centre and avoid Scotch and Spanish lines.
White's king's-side Knight removes Black's pawn on K5(e5), threatens 3..KtxBP and offers a 3..KtxP exchange. Black should be cautious not to open the e-file with his king still on it! W-Alt.
