Philidor Defense Fork Puzzle (Rated 831): Win Material — Fork Tactic
This middlegame puzzle is built around a forcing tactical sequence that wins material by creating a fork against the enemy king and major pieces. The key idea is to use check to drag the king into a vulnerable square, then exploit the exposed alignment of the rook and queen. White’s pieces are active, but Black’s tactical shot turns the tables by attacking multiple targets at once and converting activity into a decisive material gain.
