Learn How to Mate in 1: King Safety
This middlegame puzzle is a classic king-safety finish: one side’s pieces are coordinated around the enemy king, and the final blow is immediate. The key idea is that tactical pressure can outweigh material when the king has no safe squares and key defenders are overloaded or pinned. In positions like this, a seemingly active piece can actually be a liability if it leaves the king exposed to a direct mating net.
