Learn How to Win a Chess Endgame: Rook Endgame
This chess endgame puzzle shows how a seemingly active rook can become a tactical liability when it is overextended and undefended. In classical chess, endgames often turn on precise material counting, king activity, and the ability to punish a hanging piece immediately. Here, the key idea is that simplification can favor the side with the more active king and better pawn structure, even when the position looks close. The winning method is based on forcing exchanges that convert a tactical weakness into a decisive material gain.
