Busch-Gass Gambit

Im a fan of strange and obscure openings, so just wondering bout this opening, whether it is playable or just plain stupid. Thanks for your comments.

Good, Busch-Gass Gambit

After 4. Nxc6, either 4...dc   5. Qxd8  Kxd8  6. d4,   or....

         4.  Nxc6 bc  5. d4  is bad for Black.  White is up a Pawn with a full center and no weaknesses.  At least that's how I see it.

No -- I thought Black's d-pawn was clear.  4.  Nxc6  dc  5. Be2 seems safe, though. Still up a pawn and Black doesn't seem to have a concrete threat?

Instead of 3...Nc6, can Black just play 3...Qh4 threatening both checkmate at f2 and the e4-pawn? Seems more productive for me than 3...Nc6.

Usually, when one says (or in this case write) can or seems, one means this as a supposition. I just gave the idea a very mere thought. So easy with the attitude K

If you are playing an online game with this opening--you really should not be asking for help?

After 3...Nc6, is there anything wrong with 4. Nc3! (?)

After 4...Qh4 (black's only try because Nf6  will just lead to a variation of the Boden-Kieseritsky Gambit a move down and Nxe5 is hit by 5.d4) 5.g3 5...Qf6 6.Nf3 White is doing fine and seems to be a plain pawn up.

Carlsen won a blitz game pretty convincingly in this position:

What is your point?  From what exact position?

Carlsen won a game with White in that position you posted. 

Ok thanks! I thought maybe you meant he had Black in the position I posted.

It looks like it is just a worse version of the Stafford since it isn't clear that the bishop belongs on c5 while the knight definitely belongs on f6.

Black wins

Miniature victory

Playable and winnable
