Bronstein Gambit Puzzle (Rated 1260): Win Material — Tactical Refutation

This middlegame puzzle is built around a forcing tactical refutation that wins material by exploiting a pinned piece and a vulnerable queen. White’s active queen and rook coordination create a direct threat against the black queen, while the pinned c-pawn limits Black’s defensive options. The key idea is not a flashy attack on the king, but a clean simplification that turns tactical pressure into a decisive material edge. In classical chess, these moments often decide the game immediately.
