Learn How to Spot: Mate in 1
This chess endgame puzzle is a classic example of a forcing tactical finish. Even with very little material on the board, the side to move can end the game immediately by using the rook to control key squares around the enemy king. In classical chess, these positions reward calm calculation: first check for direct threats, then look for mating nets created by piece coordination, king placement, and restricted escape squares. The best move is not about winning material, but about delivering a clean checkmate.
