Learn How to Win with a Long Skewer: Endgame Tactic
This chess endgame puzzle is a classic example of a long skewer: a forcing line that attacks a valuable piece behind a more exposed one, often with check. The key idea is that active rooks become deadly when the enemy king is boxed in and the back rank or 7th rank is vulnerable. In practical classical chess, these motifs often decide games even when one side is materially ahead, because king safety and piece coordination outweigh raw material.
