Caro-Kann Defense · B15

Rasa-Studier Gambit

1. e4 c6 2. d4 d5 3. Nc3 dxe4 4. f3

An early pawn trade leaves the d-file as Black's avenue and the e-file as White's - both sides get real winning chances down their own file. Black keeps the extra pawn; White plays for time, open lines, and initiative - the classic gambit trade.
