Learn How to Mate in 2: Back Rank Mate
This chess endgame puzzle is a classic example of a forcing mating net built around king safety and the back rank. White’s heavy pieces are active on the 7th rank, and the key idea is to use a sacrifice to drag a defender away from the king’s shelter. Once that defender is removed, the remaining rook can deliver a decisive mate on the open file. In classical chess, these patterns often appear when the enemy king has limited escape squares and the rooks are perfectly coordinated.
