Learn How to Spot Mate in 1: King Safety
This middlegame puzzle is a pure mate in 1 test built around king safety. White’s pieces are coordinated to exploit the exposed black king and the weakened king zone, where even a single tempo can end the game. In classical chess, these moments often come from active piece placement, a vulnerable back rank, or a queen invasion that leaves the defender with no legal response. The key is to look for forcing moves first, especially checks that also restrict escape squares.
