The basic reason why Stu switched from gin to poker was that he was a little too good at it. So skilled in fact, that no one could equal him. Even the so-called professionals who were supposed to be the greatest at gin were demolished when they faced Stu. One such gin player was Harry Stein, called, "Yonkie". Harry suffered such a belittling beating at the hands of Stu Ungar that he evidently quit competing in it as a pro and never resurfaced at a gin rummy tournament.
Accordingly, with a honor like that it was not very long before people became shy of gambling against Stu Ungar. He could not find any matches and in his agony he began doing something no one had performed prior. Stu presented starting handicaps to likely opposing players with the wish that they might just play against him if they thought they held an advantage. He at will began from a negative position and one story has it that he even played against a constant absconder. Amid the game, he received warnings that the cheater was at it again but Stu Ungar assured that he deduced of the chicanery and he would still come away with a win, which of course, he did.
The same trend followed Stu Ungar to sin city. He won so much that the casinos began asking him not to compete in their rooms anymore. The reason for it was that other casino customers would not sit at the poker table if he were playing.
Stu Ungar is recalled better for his accomplishments in hold’em poker but he always said that he was a whole lot 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 really was, he was nicknamed, "The Kid".
