Queen And Bishop Vs Two Rooks Puzzle (Rated 1579): Skewer — Win Material

A rook skewer is a powerful tactical pattern in which a valuable piece, often the king, stands in front of a less valuable piece. Once the front piece is forced to move, the rear piece becomes vulnerable. In this chess endgame, rook activity on an open file creates a direct skewer against a pinned bishop, turning Black’s material advantage into a tactical liability.
