Skewer Puzzle (Rated 1142): Win a Chess Endgame — Short Skewer

This chess endgame puzzle shows how active rooks can turn a material deficit into a winning attack. The key idea is a short skewer: a forcing check that drags the king onto a vulnerable square and exposes a valuable piece behind it. In endgames, king activity matters, but so does king safety. When the enemy king is slightly exposed, a rook can often create decisive threats even without a queen on the board.
