Learn How to Spot Mate in 1: Back Rank Mate
This chess endgame is a classic example of a forcing tactical finish: the side to move has a direct checkmate available because the enemy king is boxed in by its own pieces and pawns. In classical chess, these patterns often appear when rooks gain access to the back rank or a key file. Even in a winning material position, you still need to look for the most forcing move first, because a single tactical shot can end the game immediately.
