Learn How to Spot Back Rank Mate: Ruy Lopez Tactics
This puzzle comes from the Ruy Lopez Berlin Defense and shows a classic back rank mate pattern in a middlegame setting. The key idea is that a seemingly active position can hide a fatal weakness when the enemy king has no luft and a rook or queen can invade the first rank. Even with material on the board, tactical motifs like a pinned pawn, an overloaded defender, and a hanging piece can combine into a forced finish.
