Learn How to Win a Rook Endgame: Skewer
This chess endgame shows how a rook can dominate when the enemy king is exposed and the opposing rook is tied to passive defense. The key idea is a skewer: first force the king into a worse square, then use checks to line up the rook and king so the defender cannot protect both threats. In classical chess, these long tactical sequences often decide supposedly quiet positions. Even with reduced material, activity and king safety can outweigh a small material deficit.
