Queens Gambit Accepted Bogoljubow Defense Puzzle (Rated 787): Win Material — Discovered Attack

This middlegame puzzle is a classic example of a discovered attack with kingside pressure. White’s pieces are coordinated around the open d-file, while Black’s king is vulnerable because the pawn shield has been weakened. The key idea is to use a forcing check to drag the king into a worse square, then exploit the alignment of the rook and queen to win material. The position rewards tactical awareness, especially when a pinned or overloaded defender is involved.
