Learn How to Spot Back Rank Mate: X-Ray Attack
This middlegame puzzle is a classic example of a back rank mate idea built around an x-ray attack on the enemy king. The key is that the opposing king is boxed in by its own pieces, so direct checks become especially dangerous. When a heavy piece can invade along an open file, it can force a sequence where captures and recaptures only help the attacker. The position rewards tactical vision more than material counting.
