Russian Game Discovered Attack Puzzle (Rated 1014): Back Rank Mate — Stafford Gambit

This puzzle comes from the Russian Game Stafford Gambit and shows how a forcing attack can override a huge material deficit. The key idea is a back rank mate pattern supported by a discovered attack and a deflection motif: the defending king is boxed in, while a pinned rook and overloaded pieces cannot coordinate in time. In practical terms, the position rewards forcing moves that create checks and remove the last defensive resource.
