Learn How to Spot Mate in 1: Back Rank Mate
This puzzle is a pure mating net: the attacking side has a direct checkmate available because the enemy king is boxed in by its own pieces and limited escape squares. In positions like this, material count matters far less than king safety. The key idea is to look for forcing moves first, especially checks that also cover the king’s flight squares. Even in a middlegame or endgame, a single well-placed queen can end the game immediately.
