Learn How to Win a Queen Rook Endgame: Skewer
This chess endgame shows how a seemingly active queen can become a target when the rook has a forcing check. The key idea is a short skewer: the checking piece drives the king onto a worse square, exposing the more valuable piece behind it. In classical chess, these patterns often decide queen rook endgame positions because king activity, piece placement, and tempo matter more than material alone. Tablebase-like precision turns a balanced-looking board into a forced win.
