Outflank Variation, Schuehler Gambit

The Schuehler Gambit arises in the Outflank Variation after 1. b4 c6 2. Bb2 a5. Black's a-pawn attacks b4, and White neither defends nor exchanges it but advances 3. b5. That pawn stands en prise to the c6-pawn and can be taken with 3...cxb5. White accepts the loss of material in exchange for time and open lines on the queenside, while the b2-bishop already bears down the long diagonal.
