Learn How to Win with a Skewer: Chess Endgame Tactic
This chess endgame puzzle shows how a seemingly active rook can become a tactical liability when the king is exposed and pieces line up on one file. The key idea is a long skewer: the stronger side uses forcing checks to drag the king onto a vulnerable square, then wins material behind it. In classical chess, these patterns often appear after simplification, when king safety matters more than raw piece activity.
