Ruy Lopez Hanging Piece Puzzle (Rated 849): Back Rank Mate — One-Move Chess Puzzle with Theory & Hints
This puzzle is a classic back rank mate pattern in a middlegame setting. The key idea is that the enemy king has very limited escape squares because its own pieces and pawns block the flight route. When a heavy piece can land on the first rank with direct support from the rest of the position, the game can end immediately. These motifs often appear when one side’s king safety is weakened and a loose piece creates a tactical entry point.
