ScrantonJack commented on how he didn't think Stu Ungar had a genius level IQ. If there is one thing about Ungar that IS NOT in dispute, it's his amazing mental capacity.His ability to count cards was unparalelled, and that is a direct byproduct of IQ. The whole concept of a multiple deck blackjack shoe came to be because of Stu Ungar and his ability to count.He won $100,000 from a Las Vegas Casino Man being able to count back four decks of shuffled cards.That means that four decks were shuffled (208 cards total). He looked at them once, and then recited off the value and suit of each card in a row, correctly, 208 times.It takes an amazing mind to do stuff like that.
