Learn How to Back Rank Mate: Endgame Pattern
This chess endgame puzzle is a classic back rank mate pattern: the enemy king is boxed in by its own pieces and has no safe flight square. In positions like this, a forcing check can be the key to a short tactical refutation, especially when the defending king is trapped behind a wall of pawns and passive pieces. The idea is to use the open file and piece coordination to turn king safety into a direct mating net.
