SuitedAces made an amazing post on the AnskyPoker.com HU Forums. Hes a limit player thats transitioning to NL and he brought up Hyperborean-Eqm, a poker bot that won the 2009 Poker Bot HU NL Championship. Now Hyperborean-Eqm (made by a team from the University of Alberta) beat another poker bot, BluffBot for 1.8bb/100. Unfortunately, you cant play against Hyperborean-Eqm online, but you can play BluffBot!
And guess what, its actually not that bad! I beat him (caught him bluffing in a big pot), but I was pretty impressed. He adjusted pretty well to my game and its definitely an awesome learning tool.
I do wonder how much better Hyperborean-Eqm is and how long before a bot can grind out microstakes NL holdem
