I honestly think this is pretty solid. Ofc there could be improvements with the move order, but I think its pretty good. I call it the Carpathian Defense.
I'm black, played against a 1200 engine (it sucks I know). Name of the opening is Carpathian Defense

looks interesting, but I don't know why the computer when nb5, advancing would lead to a benoni-like position

I'm not sure whether Chess is art, i would rather say chess is science. Results in Science can be very beautiful, like a work of art : Lagrangian and Hamiltonian formulation of mechanics, Euler-Lagrange equations, differential geometric formulation of gauge theory including gravity, Legendre transform between state fonctions in physical chemistry...
Art is (almost) *purely* esthetical with minimal elements of rationality.Science is the converse: mainly based on rationality, and there can emerge aspects of beauty, esthetics, but rather as a result (although sometimes/often also as motivation and guide), not as the determinating factor and/or justification, as in art.
Don't you think Chess is rather science than art?
Also because of counterplay. In art you should not be guided by how it will be accepted by others (else I consider it as prostitution ... — although some "artists" aim at pleasing—or shocking—their public). In chess, it's *all* about winning, i.e., "frustrating" your opponent, in some sense.

6.Qa4 is a total blunder (after already losing a tempo earlier...), the position is lost from there on, against a good player (6...cxd and -3 against white). You should test the opening against a stronger engine.

After 3...c5 you are almost 1.5 behind white. I think the correct idea to implement this idea is the pterodactyl defense (do the queen side pawn pushes after g6, Nf6) which i like to play with quite some success.

There is an opening I’ve “invented” and I use with good results:
The plan of this opening is to try to punish 2…e6. Basically, black’s bishops don’t have a lot of options other than fianchetto.

This has been played in a handful of master games

Creativity in the opening is a common trope in this site. An infamous example:
But just one of a long series...

Be actually creative and invent an endgame.
There are a few lines I made myself but they are not too far of the beaten path and I'm not trying to improve them so much as understand them better than the opponent. For example I play a a4 b5 c4 d3 e2 g3 pawn structure in the reti advance that the computer thinks I have given all advantage away but i win in that line more than when they transpose to say QGD because they don't every play the position and i do all the time. I think chessbase + chessable will make some of this more viable i just started trying to upload my stuff into chessbase today to paste back over to chessable to help memorize

After d5 Black equalizes. If you want to avoid Bb4, then just play Nf3.

Black can play either 3...d5 or 3...c5, aiming for QGD or Tarrasch. In either case, the move a2-a3 is of limited practical use (although not useless).
