Blackmar Diemer Gambit Deflection Beginner Puzzle (Rated 1093): Back Rank Mate — Mate in 3
This chess endgame-style tactical puzzle is a classic example of a back rank mate combined with deflection. White’s heavy pieces coordinate against the black king’s shelter, and the key idea is to force the defender away from a critical square so the final rook invasion becomes decisive. The position also shows how active queen and rook placement can turn material pressure into a forced mating net, even when one side is down materially.
