Queens Gambit Declined Balestra Mate Beginner Puzzle (Rated 1456): Mate in 2 — Queens Gambit Declined

This classical chess puzzle comes from the Queen's Gambit Declined and highlights a sharp middlegame mating net built around an advanced pawn and king safety. White’s passed pawn on f7 is the key tactical lever: it drags the black king into a vulnerable square and opens lines for a bishop-led finish. The position shows how a seemingly modest pawn advance can become a forcing weapon when the enemy king is stuck in the center and coordination is poor.
