Well...amazingly, so many have so, so, much to say about this very strange one, I guess I'll add my quibble to the dribble. Surprisingly, this gambit is more than playable and proves several adages. 1) Pieces beat pawns 2) developing pieces surpass capturing pawns. 3) Gambiteers are more important than gambits...and... most importantly You've got to go through it to get to it!

I would never play this: multiple pawn gambits are just not for me. If I were on the other side, I wouldn't even take the first one, unless I had to. Pieces move faster than pawns!

The Colorado gambit is less unsound with the same idea: 1.e4 Nc6 2.Nf3 f5 White plays 2.Nf3 to avoid some trappy lines in the Nimzovich defence.

correct

but these days no one play max lange attack and kotlan wiski varition

I don't understand. On the black side if the numbers are a + are they bad or good? Stockfish, in this game had a lot of + for black's moves:

And he's back - the guy who put the POS into "Positional".

...

This is called Duras Gambit - Bavarian Attack

Duras Gambit: German Opening that can lead into the Duras Gambit: Bavarian Attack (for black)...

So what do you guys/gals think?...

BLACK Nightmare! Its showing all the donots you have to avoid in the important stage of the game. If any of the Fide Top ten would be able to end in draw as black side i would change my mind but i wont. The other way is that some loud shouting it German opening is unsound and hides some lack in Character of the speaker.

two pawns and no pompensation in the development of pieces. This is hardly not to call a gambit.

No, black has a direct attack on white's king side for the 2 pawns and will eventually control the center...

Black is completely busted everywhere but the parrallel universe you're living at.

Any way show some draw or won games in the upper level class! No Fideplayer would try such a piece donating nightmare! Show some instructional ans end this nonprofund bla bla! Thanks!

Nothing is worse than the bong cloud.
