Queens Gambit Accepted Normal Variation Puzzle (Rated 1380): Win a Fork — Decisive Material Gain
This middlegame puzzle is a classic example of using active rook play to win material. White’s rook becomes a powerful tactical piece on the seventh rank, where it can attack multiple targets at once and create a fork against loose enemy bishops. The key idea is that activity can outweigh static concerns like a backward pawn or extra pawn count. When the opponent’s pieces are uncoordinated, a single forcing move can turn pressure into a decisive material gain.
