Ig bots don't have much time to think, so play stupid moves?
Canty Bot - error (I think bots don't handle premoves well)

well, not really, it's about premoves - If you don't premove bot won't make this mistake, If you do premove they somehow stuck with "opening script" and cannot include your move properly (or at least that's what I think is happening here)

If you play against bot, it's going to play nonsense in opening because it keeps evaluating best move and it's not using opening book, what I think is happening is these bots have some openings which they can choose from at start and it's scripted till a "certain point/move" - but that is irrelevant to what I am trying to point to, which is high rated bot unable to properly handle premoves for some reason in respect to that scripted opening.
For a first occurence see my first Nora-Bot error post, here we have another one, this time Canty.
I think there is issue with premoves and bots handling premoves (this is repeatable with several tries)
