Learn How to Win a Chess Endgame: Short Skewer
This chess endgame shows how a seemingly active rook can become vulnerable to a tactical shot based on alignment. The key idea is a short skewer: one piece is attacked in a way that forces it to move, exposing a more valuable target behind it. In practical classical chess, these endgame tactics often decide games because king activity, rook placement, and passed pawns all interact at once. Even when material is down, an active rook and a centralized knight can create a decisive tactical sequence.
