Learn How to Win a Chess Endgame: Rook Trap
This chess endgame shows how active rook play can turn a material edge into a decisive attack on the king. Even when one side is up in material, the defending rook may create counterplay if the enemy king is exposed and the pieces are coordinated. The key idea is to use forcing checks to drive the king into a worse square, then win the loose rook by cutting off escape routes. In classical chess, this kind of rook endgame often decides games quickly.
