Hottake: regardless of chance of detection, the incentive to bother cheating for most online play, e.g. at chess.com, is close enough to zero to not worry about it.

Probable that there are sociopaths who will do it, but, the 99% case is good faith players interested in a match for compatible reasons.

TQG reminded me I used to play every day, recreationally; I'm finding chess.com quite nice.
