Learn How to X-Ray Attack: Mate in 2
This middlegame puzzle is a classic example of a forcing tactical finish built around king safety and an x-ray attack. White’s heavy pieces line up on the f-file, creating pressure against the king and the defender behind it. The key idea is that a seemingly active defensive rook is actually vulnerable because the line of attack is already overloaded. In puzzles like this, the strongest move is often a forcing check that drags a defender onto a critical square and opens the final mating line.
