"Even human super-GMs have a really hard time "scoring" or "solving" extremely weird positions. "
I can sort of confirm that. I never learned all the formal theoretical standard chess strategies except for the basic ones. So when playing against really good players, way above my level, I could win sometimes (or allmost) simply by making unconventional (dumb by normal strategy) moves in the beginning - resulting in a non standard game where I could apply pressure in a way the opponent was not prepared for (also they underestimated me after the initial dumb moves). For me, the unconventional game was just like a standard game, I had no routine - but for the experienced one, it was way more challenging. But then of course in the standard situations, to which allmost every chess game evolves to - they destroyed me, simply for experience and routine.
Huh it's funny, in fencing that also works to a certain degree.
You can score points against e.g. national team members who've been 5-0'ing the rest of the pool by doing weird cheap tricks. You won't win though, because after one or two points they will adjust and then wreck you.
And on the flip side, if you're decently rated (B ~ A ish) and are used to just standard fencing, if you run into someone who's U ~ E and does something weird like literally not move their feet, it can take you a couple touches to readjust to someone who doesn't behave normally.
Unlike chess though, in fencing the unconventional stuff only works for a couple points. You can't stretch that into a victory, because after each point everything resets.
Maybe that's why pentathlon (single touch victory) fencing is so weird.
Watching my son compete at a fighting game tournament at a professional level, can confirm this also exists in that realm. And problem other realms; I think it's more of a general concept of unsettling the better opponent so that you can have a short-term advantage at the beginning.

IIRC Magnus Carlsen is said to do something like this as well - he'll play opening lines that are known to be theoretically suboptimal to take his opponent out of prep, after which he can rely on his own prep/skills to give him better winning chances.
The book Chess for Tigers by Simon Webb explicitly advises this. Against "heffalumps" who will squash you, make the situation very complicated and strange. Against "rabbits", keep the game simple.
In The Art of Learning, Joshua Waitzkin talks about how this was a strategy for him in tournaments as a child as well. While most other players were focusing on opening theory, he focused on end game and understanding how to use the different pieces. Then, by going with unorthodox openings, he could easily bring most players outside of their comfort zone where they started making mistakes.
