The main reason why Stu changed from gin rummy to poker was that Stu was a bit too good at it. So good in fact, that no player was able equal him. Even the so-called experts who were meant to be the greatest at gin rummy were blow away when they faced Mr. Ungar. One of these gin player was Harry Stein, called, "Yonkie". Harry Stein suffered such a crushing blow at the hands of stu that he apparently stopped playing it professionally and never resurfaced at a gin rummy tournament.
Of course, with a distinction like that it wasn’t long before people became shy of playing against stu. He could find no games and in his agony he began doing something no one had done prior. Stu issued beginning handicaps to potential competitors in the high hopes that they might compete opposed to him if they thought they held an edge. He deliberately started from a disadvantageous arrangement and one account has it that stu even played with a consistent bad egg. During the contest, he get advice that the absconder was at it once more but Stu Ungar assured that he was aware of the dishonestly and he would still come away with a win, which of course, he did.
The same problem followed Stu Ungar into sin city. He won so much that the poker rooms started asking him not to play in their respective premises anymore. The reason for it was that other casino clientele refused to sit at the poker table if he were playing.
Stu Ungar is recollected better for his abilities in texas hold’em poker but he always insisted that he was considerably more skilled at gin rummy.
He beat Doyle Brunson in the WSOP in Nineteen Eighty to become the youngest world camp. Due to his features that made him seem far younger than he really was, he was nicknamed, "The Kid".
