Queens Pawn Game X Ray Attack Puzzle (Rated 836): Pin — Win Material
An x-ray attack is a powerful tactical relationship in which one piece exerts pressure through another piece toward a valuable target. In this middlegame, the alignment of the queens, rooks, and king creates a hidden tactical refutation. White’s active rook appears to threaten important material, but Black can exploit the pin and overloaded defenders. The key lesson is that an advanced piece is not automatically safe when the line behind it contains a stronger counterattack.
