Learn How to Spot Mate in 1: Mating Net
This middlegame puzzle is a classic example of a mating net: the enemy king has too few safe squares, and one tactical shot ends the game immediately. Even when material is close, king safety can outweigh everything else. Look for loose back-rank coverage, overloaded defenders, and pieces that are tied to defense. In positions like this, a single forcing move can exploit a vulnerable king zone and turn active piece placement into a direct finish.
