Petrovs Defense Nimzowitsch Attack Queenside Attack in Chess

In the Petroff’s Defense (Nimzowitsch Attack), the queenside attack is a flank plan where Black challenges White’s queenside structure and space—often by preparing ...c5 or ...c6 followed by pressure on the queenside. A defining feature is that Black’s pieces are coordinated to strike the queenside while White’s kingside plans are still developing.
