Learn How to Win: X-Ray Attack in Chess Endgame
This chess endgame puzzle is a classic example of an x-ray attack, where a piece behind another piece suddenly becomes vulnerable once the front piece is removed. The key idea is that the apparent defender is overloaded, so a forcing capture can expose a hidden target and win material immediately. In practical classical chess, these motifs often appear when rooks and queens line up on open files, creating tactical pressure that looks harmless until the final exchange sequence is seen.
