Learn How to Win a Chess Endgame: Rook Sacrifice
This chess endgame is a classic example of using activity over material. White’s rook is active, the king is centralized, and the opponent’s king is exposed, so the right plan is to force a favorable simplification rather than chase pawns. In classical chess, rook endgames often hinge on king activity, passed pawns, and the ability to cut off the enemy king. Here, the key idea is to recognize when a tactical refutation turns a defensive move into a winning conversion.
