Learn How to Spot Pillsbury's Mate: Endgame Mate
This chess endgame puzzle is a classic example of a mating net where the king is boxed in by its own pieces and limited escape squares. In classical chess, these patterns often appear when rooks dominate open files and the enemy king is centralized but vulnerable. The key idea is to recognize when a seemingly active position actually contains a forced mate in 1 because the king has no legal flight squares and every defense is overloaded or pinned.
