Vienna Game Max Lange Defense Puzzle (Rated 1055): Queen Sac — Win a Rook
This Vienna Game Max Lange position is a middlegame lesson in turning a skewer against the attacker. White's queen lines up on the same diagonal as Black's queen, with a pawn behind it, threatening to win the queen outright; a quiet retreat would hand White exactly the tempo it wants. Instead, Black finds the most forcing resource: a queen sacrifice that forces a pawn recapture, opening the a-file and exposing White's passive corner rook. One crushing combination converts an attacked queen into a decisive material gain, the kind of sequence that decides classical chess games.
