Brilliant work. You sir are a legit genius, teach me 🥺

According to Retrograde Analysis:
'A position is recognised different if the same side does not have the right to move in the problem'

Yea I knew that is the normal definition I was asking how he defined it for his purposes, which is the same way.

Thanks, @Ben2006Tor and @IsaiasZM !
In future, could you please also paste the game record in PGN format?
It's some effort to transcribe it from the links you provide.

With pasting it in PGN format do you mean the PGN File of the "game" or just the content of the PGN? (both maybe?)

(I realized the question is a bit "dumb" you can ignore it if you also think so)

I have made a study for 3 solutions, as for now, I believe most of the positions in the site are legal. Also I am not exactly sure how to paste in PGN format.

I just mean the pgn short algebraic notation: e.g. as in this comment:

Of the 919, some 500-550 are expected to be legal.
Also, I only label issues with "proof game wanted" after I've convinced myself that the position is legal.

Also I am not exactly sure how to paste in PGN format.

If you play the game out on https://adjva4.dpdns.org/analysis
then the pgn record is shown in the box labeled PGN below.

@tromp1234 I invited you to the study as a contributor, you may edit and confirm if it works and can also see the solution, also I will try to paste the PGN.

I think you invited another user called "Tromp", not my handle "tromp1234"...
