Frustrating Scandinavian

I play 2.d4!? and transpose to the Blackmar Diemer Gambit.

You get a lot of play for a pawn, and Black won't be expecting it, but it's not for the faint-hearted.

For instance...

Here's a recent win...

You can also transpose to lines in the BDG from the Caro Kann.

The Leonhardt gambit, can guarantee at least 60% of Scandinavian players have no idea what this gambit is

That's weak and it won't help a thing. If you win using this, your opponents are unprepared.

Here, you fail to grab the exchange and a pawn for free.

And here, you move your Queen 4 times in the seven opening moves without any good reason.

Here, I admit that Bg8 is one of the most spectacular moves I've ever seen.

Here, you blunder the exchange and a pawn out of nowhere.

Here, you pick a free rook at move five, and somehow after ten moves you are totally lost.

Practically all your games go like that. And this means that learning opening ABC (any opening) is time wasted, as it won't solve your problem- your tactical vision, which is still very weak.

Actually, it's a main line many titles players have played.

Maybe in blitz and bullet. No good player is using this at regular time controls.

For beginners, it is as good or bad as any other opening: They will blunder no matter how good their position is, and they will win if their opponents blunder more than them.

In over-the-board rated tournaments - at the 1600-2000 level - I used to play:

As someone who plays the Center Counter Defense...

There are 3 attacks by White we see on a regular basis.

1. The ICBM... basically standard development thwarts White's advantage (Especially if you play lines that as Black, you develop ...Bf5

2. The Tennsion Gambit... basically standard development thwarts White's advantage (Especially if you play lines that as Black, you develop ...Bf5

3. The Blackmar- Diemer Gambit. If you play the Mieses-Koptc var basically standard development thwarts White's initiative that he gets from playing the gambit

(anyone see a trend here?) 

Against the Center Counter Defense playing the BDG you basically have the Ryder Var and the main line (if you can call it that)

Ryder Gambit

There is a line called the Ziegler defense in BMG: Black's development in Center Counter Defense comes naturally along that line (but with an extra pawn !!!)

Moral to the story.... Just learn to play the Main lines...

kind of looks like what I play against the scotch

I’ve faced this gambit! I’m not a big Scandinavian player, I think I won the game but didn’t really know what I was doing.

Ok. Maybe scrub what I said about the BDG.

Just play the mainline Scandi, and as White, at my level, you'll most probably end up winning
