Oslo gambit un-refuted

During one of our many blitz games, my dad pulled out a little gambit in the scandinavian, which I call the Oslo gambit. This goes e4 d5 exd4 c6. It has had a suprisingly good score against me, so I am looking for a way to refute it.

My first thought was to invent a gambit of my own to get him offtrack. I call it the okneb gambit. e4 d5 e5 c5 b4. Bad.

my second thought was what I call the trojan defense. e4 d5 g4. Bad

If you have any thoughts on how to refute the oslo, please comment!

If you like Gambits, there's always the Blackmar Diemer

1. e4 d5 2. d4 dxe4 3. Nc3

Either:

A) 3.d4 cxd5 4.c4, transposing into the Panov attack, which you can read volumes on if you want to figure out how to gain an advantage.

or

B) 3.dxc6 Nxc6, and develop with Nf3 and Bb5, pinning the knight.  Then trade the bishop for the knight as soon as black castles.  Yes, you're giving up the two bishops.  Big deal.  You're up a pawn, and announcing your intent to trade everything off till you've got a won endgame.

Plenty of examples of both strategies available in any online database.

I hate a lazy gambiteer!

The French is full of opportunities for an enterprising attacker.  The immediate Be3 springs to mind.  But the advance and classical are rife with gambit opportunities as well.  Not all 100% sound, but such is life!

But during my gambiteering days, I preferred to take the French and CK spoilsports into exchanges, with either a Monte Carlo or Panov, both of which offer plenty of open lines and attacking chances.  Sure, it's not BDG chess, it's "real" chess instead, but it's the kind of real chess an attacker can sink his teeth into and have a good time with, even if he runs the risk of running afoul of a well-prepared black theory maven.

I tried dxc6, and he played Nf6.

Well, then 4.cxb7 Bxb7, and you wall yourself up defensively.  A la d4, Nf3, and either Be2 and 0-0, or g3, Bg2, and 0-0.  By the time he can mobilize his forces on you, no way in hell the extra tempo or two he can salvage is worth two pawns.

Did this become a discussion of dynamic gambits? If so I have a suggestion. Why not throw in a latvian gambit in some amateur games? Playing blitz this is effective if you're good with sharp tactics and don't get caught off guard very often. Plus you can play it against almost any e4 opening.

You aren't going to find a refutation for this move since white will do best not to take it, there is no doubt that black gets more than ample compensation for the pawn.

An 1.e4 player playing the BDG against the Scandianavian won't be surprised by a transposition to a French, this is likely only the case from 1. d4.

Actually, I tried another gambit idea, no idea what it's called though, I just made it up and just play it in casual games.  1. e4 d5 2. d3 dxe4 3. Nd2 exd3 4. Bxd3 the difference being Nd2 instead of Nc3, with KIA-like Nd2 (c4 or f1) action...if Black declines the pawn, you get a KIA vs. Scandinavian!

I'm with Fortescue: I have transposed from a Scandinavian to a Panov Attack (by the move order 1. e4 d5 2. exd5 Nf6 3. c4 c6) a number of times with complete success, since most people who trot out the Scandinavian are just being lazy and not trying to learn any openings. In my case you may have problems with 3...e6 as a countergambit, but from the move order you gave, he's already committed to the c6 move.
