7. d3 e5 8. Nd2 followed by nb3 or even ne4!? with the plan of developing the bishop to d2 should give white some advantage imho, i am not too familiar with the grobs opening, but i will say that white should be able in the long run able to convert the extra exchange.
Unless there is some crazy forcing variation there is no reason why white can not consolidate his extra exchange.
Are you talking about the variation I posted?
Does anyone else here play the Fritz Gambit?
I chose this variation because it's far flashier.
