Stu Unger like reads

[arod15]

Stu Unger, perhaps the greatest holdem player of all time, certainly the most gifted Gin rummy player of all time. And a notorious card counter. He once counted the last three decks of an 8 deck shoe without one mistake! Do you think his great ability in holdem was due to a remarkable mathamtically system were he could pinpoint you to a hand. I know it sounds absurd, but again this guy counted the last three decks of an 8 deck shoe flawlessly. Was he so genious that he had his own system?
