Vienna Game Unpinning Chess Puzzles

Vienna Game Unpinning is a tactical motif in the Vienna Game where one side breaks a pin on a knight or bishop by moving the pinned piece, interposing a piece, or forcing the pinning piece to retreat. It often appears after 1.e4 e5 2.Nc3, when White develops quickly and Black’s bishop or queen tries to pin a knight on c3 or f3. The defining feature is that the pin is not allowed to stay static; the side under pressure uses the position’s open lines and rapid development to unpin with tempo.
