The above game can be found in both the chess.com and ChessBase databases. It's probably either a bizzare series of transcription errors or the players deciding to screw with everyone.
what is the point of this gambit

It's obviously a joke game.
No, it is not, but it was quite crazy, in fact.
hey we know that the game is of full blunder

I think the point is that this might be a "real" game, but I can also post a real game with my 4-year old that has just as much merit. This game might as well have been played by beginners.
It has no merit to be deemed a "real" game, because a "real" game is a game where two people are actually competing for the win. This looks like a mockery.

yeah a stupid game
It is a very positional game, and it was played properly. Please, analyse it, with solid statements before giving adjectives.
Thanks.
It's a blitz game. If registered via a DGT board, then it's absolutely sure it's full of errors. Blundering stuff at random has nothing to do with "positional game", and I'm sure both Andreas and Ruck can play much better than that, even in blitz mode (unless they both drank generous quantities of tsikoudia before the game).
"Hey, let's play a contest and if you move a piece, you have to take a shot! Let's see how this game turns out!"
That sounds about right!
but why he did not took the bishop
