Learn How to Spot Mate in 1: London System
This London System puzzle is a classic middlegame mating pattern where king safety outweighs material. White’s pieces are coordinated around the enemy king, and the key idea is that the defender’s back rank and pawn shield have been overextended. In positions like this, a seemingly active queen and knight setup can suddenly become decisive because the king has no safe escape squares. Always look for forcing moves first when the opponent’s king is exposed.
