Learn How to Win Material: Short Skewer
This chess endgame puzzle is about spotting a forcing tactical idea that wins material by creating a skewer against the enemy rook and king. The key is that the opponent’s last move has left a piece vulnerable, and the active rook can use check to drive the king onto a bad square. Once the king is forced aside, the skewer becomes decisive and the hanging rook can be collected, turning a slightly better endgame into a winning one.
