Learn How to Spot Mate in 1: Pillsbury's Mate
This chess endgame puzzle is a classic example of a mating net where one forcing move ends the game immediately. The key idea is that the enemy king has very limited escape squares, and a rook can exploit the open file to deliver a direct checkmate. In classical chess, these patterns often appear when pieces are active and the king is boxed in by its own pawns and pieces. Always scan for checks first when the position looks quiet.
