Blackmar Diemer Gambit Accepted Fork Puzzle (Rated 997): Win Material — Fork Tactic

This middlegame puzzle is a classic example of a tactical shot that wins material by forcing the king and pieces into awkward squares. White’s queen becomes highly active, creating a direct check that also exposes loose pieces and overloaded defenders. The key idea is not a long attack, but a forcing sequence that improves White’s piece activity while Black’s king remains vulnerable in the center and Black’s heavy piece coordination is stretched.
