Learn How to Mate in 1: Endgame Finish
This chess endgame puzzle is a classic example of a forced mate in 1, where one active rook dominates the position and the enemy king has no escape squares. In classical chess, these finishes often appear after simplification, when piece activity and king safety matter more than raw material. The key idea is to notice when a seemingly ordinary capture or check also seals every flight square and ends the game immediately.
