Learn How to Spot Mate in 1: Back Rank Mate
This middlegame puzzle is a classic example of a forcing mating net where one active rook and an exposed king combine for immediate tactical finish.

In classical chess, these one-move finishes often appear when a major piece is overloaded or a key square becomes undefended.
