Learn How to Spot Mate in 2: Back Rank Mate
This puzzle is a classic mating net built around king safety and piece coordination. White’s active knight and rook work together to exploit the exposed black king, which has limited escape squares and is vulnerable to a forcing check. Even though Black is materially ahead, tactical patterns can override static evaluation when the king is boxed in. The key idea is to use a forcing move that drives the king onto a vulnerable square, where a rook can deliver the final blow.
