Queens Pawn Game X Ray Attack Puzzle (Rated 983): Spot — Back Rank Mate
A back rank mate occurs when a king is trapped by its own pieces or weakened pawn shield, allowing a rook or queen to deliver a decisive check along the back rank. In this middlegame position, Black’s attack depends on exploiting restricted escape squares and the alignment of heavy pieces. The tactical idea also features an x-ray attack: one rook operates through another target, creating a forcing sequence that leaves the king without a legal defense.
