Queen Rook Endgame Puzzle (Rated 1154): Spot Back Rank Mate — Queen Rook Endgame

This puzzle is a classic back rank mate pattern in a queen rook endgame setting, where the king’s escape squares are stripped away by its own pawns and pieces. Even with material down, the side to move can win immediately if the enemy king is boxed in and a rook or queen can deliver a direct mating blow on the first rank. In classical chess, these motifs often appear after a forcing sequence that leaves the opponent’s king with no luft.
