Ruy Lopez Other Variations Puzzle (Rated 1474): Win Material — Crushing Tactic

This middlegame puzzle is all about a crushing tactical refutation that wins material by exploiting loose pieces and a pinned pawn. White’s king is safe, but the position contains several tactical weaknesses: an undefended bishop, a vulnerable queen, and a pinned pawn tied to king safety. Black’s best play turns those weaknesses into a decisive material gain by forcing exchanges that leave White unable to keep the extra piece advantage intact.
