Learn How to Win the Rook Endgame: Zugzwang
This chess endgame puzzle is a classic example of how active pieces and king activity can decide a seemingly equal rook ending. White’s rook is ideally placed to challenge the enemy rook, and the kings are close enough to make every tempo matter. In positions like this, the side to move must look for tactical refutations that convert activity into material gain. Even a single accurate exchange can transform a balanced endgame into a winning one.
