Learn How to Mate in 2: Back Rank Mate
This middlegame puzzle is a classic example of a mating net built around king safety and piece coordination. White’s heavy piece activity on the open file creates a forcing check that drags the black king into a cramped defensive setup. The key idea is not material gain, but using a forcing move to expose the back rank and remove the last defender. Once the king is boxed in, the follow-up finishes the attack with a clean checkmate.
