Lichess has a checkmate captcha that I think is cute.

It requires you to solve a mate-in-one puzzle to, e.g., post on the forums.

(Sorry, don't have a better link, there wasn't any non-technical I could find about it).

Because computers turned out to be so bad at chess? :)

Reverse captcha: only robots can reprove one of the Euler problems on the fly? Statistically speaking we can round the people who can into the outlier group, right?

That's actually interesting:

Like when games detect aimbots, they don't ban people, but put them in an aimbot bracket, so everyone you play with is a cheater.

Provide a captcha that is essentially harder for a human to solve, but trivial for either a human or an AI, and transparently separate them into two communities.
