I can’t remember the last time I played an illegal move tbf, and I’ve played 7 games of chess this morning already to give you an idea of total games played

You have never made an illegal move, ever?

The bar isn’t “I didn’t make an illegal move this morning” it’s “something a 1400 ranked player would never do”.

My entire point is that it happens. Not often, but also not “never”.

This argument is pretty flimsy. ChatGPT makes illegal moves frequently. In all my years of playing competitive chess (from 1000 to 2200), I have never seen an illegal move. I'm sure it has happened to someone, but it's extremely rare. ChatGPT does it all the time. No one is arguing that humans never make illegal moves; they're arguing that ChatGPT makes illegal moves at a significantly higher rate than a 1400 player does (therefore ChatGPT does not have a 1400 rating).

Edit: Without reading everything again, I'll assume someone said "never." They're probably assuming the reader understands that "never" really means "with an infinitesimal probability," since we're talking about humans. If you're trying to argue that "some 1400 player has made an illegal move at some point," then I agree with that statement, and I also think it's irrelevant since the frequency of illegal moves made by ChatGPT compared to the frequency of illegal moves made by a 1400 rated player is many orders of magnitudes higher.

No I definitely have, it’s just so rare I can’t remember when I last did it. I do remember playing one in a blitz tournament 20 years ago! But if this is the first game they played, or if it happens in 1/10 matches, that’s wild

A broken clock is correct two times a day. But my broken clock isn't 1400 player although it might seem to be.

I read an article about a pro player who castled twice in a game and my son hates castling so I make a point of castling twice as often as I can to tease him and attempting other illegal moves as a joke but he never ends the game because of it.

If I was playing that monstrosity though I would play something crazy that is far out of the opening book and count on it making an illegal move.
