Learn How to Mate in 1: Back Rank Mate
This puzzle is a classic mating net where the enemy king has very limited escape squares and the heavy pieces coordinate to finish the game immediately. In chess endgame and classical chess positions, these patterns often appear when one side’s king is boxed in by its own pawns and pieces. The key idea is to notice direct checks that cannot be blocked, captured, or escaped from because the king’s flight squares are already controlled.
