Learn How to Spot Mate in 1: Queen Trap
This chess puzzle comes from the Queen's Gambit Accepted and shows how a seemingly normal middlegame can hide a forced mate in 1. The key idea is king safety: when the enemy king is stuck in the center and the back rank or key escape squares are under control, a queen can sometimes deliver immediate checkmate. In classical chess, these patterns often appear after development lags or loose piece placement create a sudden tactical collapse.
