Queen's Gambit Accepted Saduleto Variation Puzzle (Rated 1135): Win Material — Discovered Attack
This middlegame puzzle is a classic example of a discovered attack turning a strong tactical idea into a decisive material win. White’s queen and bishop coordination looks active, but Black can use a forcing check to drag a defender away and expose the queen on d4. Once the key defender is removed, the follow-up wins the queen outright and leaves Black with a crushing advantage. The position rewards seeing how one forcing move can change the whole board.
