Learn How to Spot Mate in 1: Back Rank Mate
This puzzle is a classic mating-net finish in a simplified position where king safety matters more than material. In the chess endgame and middlegame alike, a queen or rook can exploit a trapped king when escape squares are blocked by its own pawns and pieces. The key idea is to recognize when the enemy king has no flight square and the checking piece can deliver immediate mate on the back rank or along the h-file.
