Learn How to Win a Chess Endgame: Discovered Attack

This chess endgame is a classic example of how active rooks and king safety can outweigh static material balance. The key idea is a discovered attack: one move creates a direct threat by opening a line for the rook, forcing the opponent’s king into a narrow defensive corridor. In rook endgames, even a single tempo can decide everything, especially when one rook is already dominating the seventh rank and the enemy king is cut off.
