Queens Gambit Declined Queenside Attack in Chess

The queens gambit declined queenside attack is a QGD plan where Black accepts the declined structure and White tries to generate pressure on the queenside rather than the kingside. A defining feature is the pawn structure after the QGD exchange/decline (often with pawns on c4/d4 for White and c6/d5 for Black), followed by White’s queenside expansion with moves like c5 or b4 to gain space. The attack is carried out by coordinating queenside pieces (typically the c- and b-files) against Black’s queenside pawns and queenside king safety.
