Learn How to Spot Mate in 1: Queen Checkmate
This middlegame puzzle is a classic mate in 1 pattern: the attacking queen can deliver a direct checkmate because the enemy king is boxed in by its own pieces and weakened dark-square coverage. The position also shows how king safety can outweigh material. Even when one side is materially ahead, a single tactical oversight can end the game immediately if the king has no flight squares and no piece can interpose or capture the checking piece.
