Zilbermints Gambit

The Zilbermints Gambit meets the Scandinavian Defense with 2. b4. White neither exchanges on d5 nor defends the e-pawn and instead advances the b-pawn, leaving e4 en prise. Reference analysis classes the move as an error, and engines give Black a clear advantage. Black most often accepts with 2...dxe4. The space-gaining 2...d4 is less common but scores especially well for Black, and 2...Nf6 is also seen. The line is rare in practice.
