Learn How to Spot Mate in 3: Rook Sacrifice
This chess endgame puzzle is a classic forcing sequence where activity matters more than material. White’s rook is ready to invade, and the enemy king is boxed in by its own pieces and weak back rank squares. The key idea is to use a forcing check to drag the defender onto a bad square, then exploit the pin and the overloaded rook. In classical chess, these patterns often decide games instantly when the king has limited escape squares.
