Here’s an interesting ‘tell all’ story about poker bots in action. Personally, I’m still on the fence, as I feel most poker bots play abc style ‘robotic’ poker that all low limit donks play – and while these bots may spew chips slightly less than a real human, they are not so advanced to be thinking along multiple lines – therefore, these bots would be no tougher to play against than your regular micro-stakes donk. Maybe I’m just naive, or hopeful, or interestingly enough overconfident (like most poker players).
