user23245: I remember seeing somewhere an opening line, where one side gets rook and the other one 5 pawns, it was pretty sharp. I also remember that it's now considered dubious, because one of the sides was proven to be much better. Unfortunately I don't remember which side was which and also the parent opening or the starting moves. Does this line come to mind to someone? It would be greatly appreciated.

user7726: Is it this line in the Advance Caro-Kann of which you are thinking?
