Learn How to Spot Mate in 1: King Safety
This middlegame puzzle is a pure king-safety lesson: one side’s pieces are coordinated around the enemy king, and the final blow is immediate.

The key idea is to notice when the king has no safe flight squares and a single forcing move creates an unavoidable mating net.
