Learn How to Spot Mate in 2: Back Rank Mate
This middlegame puzzle is a classic example of a back rank mate pattern, where the enemy king is boxed in by its own pieces and pawns. White’s queen and bishop coordinate to create a forcing attack on the king’s shelter, while Black’s heavy pieces are poorly placed to defend the back rank. The key idea is not material, but forcing checks that leave the king with no safe escape squares and no way to block the final blow.
