A strong opening for beginners and early-intermediates

I have strong opening setup for beginners and early-intermediates that is not liked much by engines but at the level I mentioned is fire. It is for black, and I myself had a good score with it.

It actually is a setup, or a system

Even if in many position white can take some slight advantage that would need strong positional understanding that at lower levels doesn't even matter. Also from personal experience I had a good winning percentage

okay this looks very similar to how I usually play black so I just wanted to ask if there is any advantage from playing d6 instead of d5 at that point? because it looks like instead of Bd3 more aggressive players for white will just push d5. granted taking on d5 with the e pawn will leave you a pawn down and so it would be better to then push your e pawn to e5 but your queenside becomes cramped.

also for move 8 for black I might consider just Bc6, with the idea of pushing a6 once I get my next turn to stop the knight from coming down, with eventually getting the queen out. I'm not sure if one's better but I typically don't like trading queens until a little later or once I get a pawn up.

At first it looks like a French Defense, then it have the small center defense and Kings Indian parts, and ultimately I don't know what it is 😅. But I believe at <800 openings doesn't even matter, not hanging pieces do, and between 800 and 1000, mostly the simplest openings will be played (Italian, Ruy Lopez, and London) so you won't see white playing that good and positional of a Queens Pawn game. And finally from 1000 to 1300 is where the player skill is better but they still won't have a good positional understanding. I'm curious what rating range did it work best for you?

You missed the term "Beginners and early intermediates". This is not the objectively best way to play but the reason I delay d5 is beginners don't handle central tension properly, and also and this level complex strategy matter less but what matters is a simple game where is opponent has more channces to make errors
