Learn How to Spot Mate in 2: Back Rank Mate
This middlegame puzzle shows how a seemingly active defense can collapse when the king has no safe flight squares. White’s rook activity on the seventh rank and bishop pressure on the queenside combine to create a forcing mating net. The key idea is that the opponent’s king is boxed in by its own pieces and pawns, so a single forcing check can set up a direct finish. Patterns like this are common in classical chess and tactical game review positions.
