Learn How to Win Material: Long Skewer
This chess endgame puzzle shows how a rook can create a long skewer to win material when the enemy king is forced into a narrow route. The key idea is not a flashy mate, but a forcing sequence that improves rook activity and exploits loose back-rank coordination. In classical chess, these patterns often appear when one side has active rooks, a weakened king shelter, and a hanging piece that cannot be defended in time.
