Stu Ungar
The primary reason why Stu changed from gin to poker was that Stu was a bit too skilled at it. So skilled was he, that no player possibly could stand up to him. Even the commonly called professionals who were meant to be the best at gin were beat when they played against Stu. One of these gin rummy masters was Harry Stein, called, "Yonkie". Harry Stein was handed such a belittling blow at the hands of stu that he allegedly stopped playing it professionally and never showed up at a gin rummy tournament.
Accordingly, with a image like that it wasn’t very long before gamblers became afraid of playing against stu. He couldn’t find any games and in his desperation he started doing something no one had attempted before. Stu presented starting handicaps to potential opponents in the high hopes that they might just play against him if they believed they had an advantage. He at will began from a negative position and one story has it that he even competed against a regular bad egg. Mid match, he received advice that the bad egg was at it once again but Stu Ungar assured that he knew of the dishonestly and he would still acquire a win, which of course, he did.
The same problem followed Stu Ungar into Las Vegas. He won so frequently that the poker rooms began asking him not to gamble on their poker rooms anymore. The basis for it was that other casino players would not be seated at the table if Stu was playing.
Stu Ungar is recalled more for his abilities in holdem poker but he always said that he was much more accomplished at gin rummy.
He defeated Doyle Brunson in the WSOP in Nineteen Eighty and became the youngest world camp. Due to his features that made him seem far younger than he was, he got the nickname, "The Kid".
