Learn How to Spot Mate in 1: Back Rank Mate
This middlegame puzzle is a classic example of a back rank mating net built around an overloaded defender and a hanging piece.

Even though Black is materially ahead, king safety overrides material when the final rank is vulnerable and the key defender is pinned or trapped.
