I don't really play against bots much unless I want to try things ot practise (which admittedly is not often enough), but I've noticed that beating bots is easier than humans for some reason. Sure, some of them blunder pieces here and there so that gives you advantages depending on the bot level, but even the more advanced bots that are supposed to play well are still easier to beat than humans. Why?
Because bots do not adjust well.
