Queens Gambit Declined Harrwitz Attack Puzzle (Rated 818): Win Material — Queens Gambit Declined
This middlegame puzzle comes from the Queens Gambit Declined and shows how a loose king-side setup can turn into a decisive material win. White’s active queen and bishop coordinate against Black’s exposed kingside pieces, especially the bishop on g4 and the knight on h5. The key idea is to notice when an attacked piece is also part of a tactical sequence, allowing White to simplify into a clearly better endgame-like position with extra material.
