Learn How to Back Rank Mate: Mate in 3
This puzzle is a classic middlegame mating net built around a vulnerable back rank and overloaded defenders. White’s pieces are coordinated to exploit the black king’s limited escape squares, while a tactical deflection clears the way for a decisive rook invasion. The key idea is that one forcing check can drag the king into a worse square, after which the remaining defenders are unable to cover the file. It is a strong example of how a small material edge can turn into a forced finish.
