Learn How to Spot Mate in 1: King Safety
This middlegame puzzle is a pure king-safety finish: the attacking side has built a mating net around the enemy king, and one forcing move ends the game immediately.

In classical chess, these are the positions where material count matters less than the final geometry around the king.
