Learn How to Spot a Mate in 1: Back Rank Mate
This puzzle is a classic mate in 1 pattern built around king safety and piece coordination. The key idea is that the enemy king is boxed in by its own pieces, leaving a single forcing move that ends the game immediately. In positions like this, a rook on an open file can become the deciding piece when the back rank is vulnerable and escape squares are covered. Always look for direct checks before considering anything slower.
