Queens Gambit Accepted Rosenthal Variation Puzzle (Rated 1158): Win Material — Discovered Attack

This middlegame puzzle shows how a tactical shot can turn loose pieces and king exposure into a decisive material gain. White’s queen and rook activity create pressure on the back rank and along open lines, while Black’s pieces are awkwardly placed and vulnerable to a tactical refutation. The key idea is that a forcing capture can reveal a discovered attack, win major material, and leave the opponent’s king unable to coordinate defense.
