Queens Gambit Accepted Furman Variation Puzzle (Rated 1717): Win Material — Tactical Refutation

This middlegame puzzle is about turning pressure into a clean material win. White’s pieces are active, but Black can exploit tactical details around the queenside and the c-file. The key idea is to notice when a defended-looking piece is actually vulnerable because of pins, loose coordination, and a forcing capture sequence. In positions like this, the best move is often a forcing tactical refutation rather than a quiet improving move.
