Learn How to Win a Chess Endgame: Rook Skewer
This chess endgame shows how a rook can dominate when the enemy king is exposed and the back rank or first rank is vulnerable. The key idea is a short tactical sequence that uses check to force the king onto a worse square, then wins material by lining up the king and rook. In practical play, these patterns often decide otherwise equal rook endgames because activity and king safety matter more than raw material.
