Continuation for 1. d4 e5 2. dxe5 d6

I mean Black is basically hoping for either cheapos on h2 or to get the rooks out fast and get x-rays on the king. If White can avoid that stuff he should be fine.

I think that in bullet games it's difficult to play against an (pseudo-)active position even if the gambit is incorrect. I like to do the following:

Now they have to defend. Most of the guys who play 1 ... e5 don't play anything else so these types of positions will be really uncomfortable for them if you prepare a little bit.

Stefan Buecker, one of the great experts on offbeat lines, recommends 1.d4 e5 2.de5 d6 3.Nf3 Bg4 4.Bg5 Qe7 5.ed6 Bd6 6.Nbd2. Black doesn't have enough for the pawn.
