Learn How to Win with a Short Skewer: Endgame Tactic
This chess endgame puzzle shows how a seemingly active rook can become vulnerable to a short skewer when the king is forced into a narrow set of squares. The key idea is that checks often do more than win tempo: they can also expose a higher-value piece behind the king. In classical chess, this kind of tactic is especially powerful when pieces are loose, the king is centralized, and one forcing move creates a direct tactical chain.
