Learn How to Win with a Long Skewer: Endgame Tactic
This chess endgame puzzle shows how a rook can dominate a king and force a long skewer against loose material. Even with a large material edge, the side to move can be in trouble if the enemy rook becomes active and the king is exposed. The key idea is to use checks to drive the king onto a vulnerable square, then line up the rook so it attacks along a file or rank while also threatening a valuable piece behind it. In classical chess, this kind of technique often decides simplified positions.
