Learn How to Spot Back Rank Mate: X-Ray Attack
This puzzle is a classic middlegame mating net built around king safety and an x-ray attack. White’s heavy pieces coordinate on the f-file and seventh rank, creating pressure that the black king cannot comfortably answer. The key idea is that a seemingly active defensive resource is actually overloaded by the mating threat. In classical chess, these patterns often appear when the king is boxed in by its own pieces and the back rank becomes vulnerable.
