This chess endgame hinges on a tactical shot that turns an active rook into a winning simplification. In rook endgames, activity often matters more than raw material, and a single check can force the enemy king into an awkward recapture. Here, the key idea is to notice that the opponent’s rook and king are aligned in a way that allows a forcing exchange. Once the heavy pieces come off, the king activity decides the rest.
