A smidge off topic, but I'm curious; is there a place where you can upload (say) a chess bot you designed and play against other uploaded chess bots? (or any move base game, even as simple as 'paper rock scissors')?
I don't do it myself, but more info here: https://lichess.org/blog/WvDNticAAMu_mHKP/welcome-lichess-bo... And here: https://lichess.org/api#operation/botAccountUpgrade

Sadly, FICS has been dying a slow death for the past 10 years ... but there are plenty of idle CPU accounts waiting for an opponent.
