As a wise man once said, whenever you play chess bots, you should know that they can't play real human moves, they play mainly engine moves. So basically you should take the bot elo, divide it by 2, then compare it to yourself.
even against humans, never resign. more than once, I've stalemated entire armies and showoffs that can't finish a game with 2 queens and a bishop against a lone king! opponents can blunder advantages away too. it ain't over until there's opera happening
