Ooh, but still on the subject of chess, there's a video game which is an exploration of something maybe closer to what you're talking about.

In the Troll's version of chess, if you catch your opponent cheating, you get to cheat in turn to "rectify" it.

The history of chess is also full of high-profile cases of this nature, usually the centers of controversies. Again, this is in a setting where that would be resolved by a judge, so still not quite what you're looking for.

Ah, I think the most in-depth writing I've ever seen on that specifically is the MtG Infraction Procedure Guide, which you may already know about? It's not really an analysis but a how-to guide for people running events, and it focuses on a judge intervening rather than the players themselves.

Basically, he says that if you're playing for fun, you should not just allow take-backs, but actively offer them when you see that your opponent's misplayed.
If you're playing to win, though, he thinks the touch-move rule should be followed strictly.

"By this generous civility (ſo oppoſite to the unfairneſs above forbidden) you may, indeed, happen to loſe the game to your opponent, but you will win what is better, his eſteem, his reſpect, and his affection; together with the ſilent approbation and good-will of impartial ſpectators."

"Snatch not eagerly at every advantage offered by his unſkilfulneſs or inattention; but point out to him kindly, that by ſuch a move he places or leaves a piece in danger and unſupported; that by another he will put his king in a perilous ſituation, &c."

In The Morals of Chess, Ben Franklin briefly touches on this in his very last paragraph.
"Laſtly, If the game is not to be played rigorouſly, according to the rules above mentioned, then moderate your deſire of victory over your adverſary, and be pleaſed with one over yourſelf."

I think there've been 3 new scratch versions since then, so the checkbox that shows the variable that tells you what key to press to use each new spell didn't preserve its checked state. The first spell is W to jump, then everything after that I'll let you hunt your keyboard for ;)

Well, I looked up my old Scratch account. Unfortunately I pretty aggressively deleted a lot of my old projects at the age of around 16, so there's only one real surviving candidate, which I made at 14:

The orbs are only collectable until #6.

Now I'm trying to think of a reason why the edge of a disk isn't a hole.

Oh ok

I could see doing a "remaster" eventually where each page gets a half or even full sheet of paper and I have room to flesh things out. But I do think the extremely limited size I choose is a large part of how I managed to even complete it in a reasonable amount of time and effort.

Thanks for the thoughtful review! In hindsight I really constrained myself with the physical format - each page needing to take up only 1/8 of a sheet of paper. It already came out with legibility issues, and that was with me *cutting back* how much information I could convey.
