Learn How to Spot Back Rank Mate: X-Ray Attack
This puzzle is a classic back rank mate pattern in a middlegame setting, where the king’s escape squares are restricted by its own pawns and pieces. The key tactical idea is an x-ray attack: a heavy piece lines up on the same file, creating a direct threat that cannot be met by normal defense. Even when material is balanced or better for one side, the exposed king can make the position tactically lost in a single sequence.
