Learn How to Win a Chess Endgame: X-Ray Attack
This chess endgame puzzle is a classic example of how rook activity can outweigh material. The key idea is an x-ray attack: a rook lines up through one piece to pressure another behind it, creating a forcing sequence that wins material or promotes a passed pawn. In classical chess, these endgame motifs often decide the game because active rooks can dominate passive defenders and convert small advantages into a decisive result.
