Vienna Game Max Lange Defense Puzzle (Rated 1321): Sacrifice the Queen — Win Material

Not every winning middlegame tactic ends in checkmate — many instructive finishes convert a material deficit into a decisive edge by trading the most powerful piece. Here Black is down a rook and a knight, yet one forcing sequence flips the material ledger. The key is a deflection sacrifice: lure the enemy queen onto a square she cannot defend. Once she is forced to recapture on an unsafe square, a waiting bishop finishes the job, stripping White's heavy artillery and leaving Black's army ruling the board.
