Vienna Game Vienna Gambit Discovered Attack Chess Puzzles

In the Vienna Game, Vienna Gambit, a discovered attack happens when one piece moves and reveals an attack from a bishop, rook, or queen behind it. The defining feature is the gambit structure after White plays f4, often with the bishop on c4 or b5 and the e-file or diagonal becoming tactically active. In these positions, the moved piece is usually not the real attacker; it is the screen that suddenly opens a stronger line.
