Learn How to Spot Mate in 2: Back Rank Mate
This middlegame puzzle is a classic example of a back rank mating net built around forcing checks and overloaded defenders. White’s queen and rook coordinate to exploit the enemy king’s limited escape squares, while the pinned and passive black pieces cannot help in time. The key idea is that a forcing sacrifice can drag a defender away from the critical file, allowing the remaining rook to deliver the final blow. In classical chess, these patterns often appear when the king is boxed in by its own pieces.
