In short: Stu Ungar was a gambling prodigy whose intellect was so sharp it bordered on the supernatural. From mastering gin rummy at age ten to becoming a three-time World Series of Poker champion, his life was a high-stakes odyssey of mathematical brilliance, extreme addiction, and an almost impossible level of competitive will.

Born in Manhattan's Lower East Side to a bookmaker father, Ungar was exposed to gambling from birth. He possessed a prodigy-level IQ and total recall, allowing him to master gin rummy by age 10. By his late teens, he became so dominant at the game that professional opponents eventually refused to play him. To keep generating action, Ungar began offering extreme handicaps—such as letting opponents see the last card in the deck or playing every hand from the dealer position—just to maintain a seat at the table.

Ungar's transition to poker was marked by historic dominance. In 1980, he became the youngest champion of the World Series of Poker (WSOP) Main Event, defeating legend Doyle Brunson after reportedly reading Brunson's own book on Texas Hold 'Em the night before. Only two individuals throughout poker's past have secured three WSOP Main Event victories, while he remains the sole winner of Amarillo Slim's Super Bowl of Poker on three occasions. His reputation was so formidable that casinos eventually banned him from gin tournaments because players refused to enter if he was present.

Despite his accolades, Ungar’s life was defined by a grueling cycle of brilliance and self-destruction. He struggled with severe cocaine addiction, which began in the late 1970s. His physical toll was so visible that peers feared he wouldn't reach age 40. Yet, his determination remained unparalleled; in 1997, despite being nearly broke and physically exhausted from seeking funds to play, he entered the WSOP Main Event as a last-second addition. He carried a photo of his daughter in his wallet, using her as the primary motivation to navigate a final tournament run that saw him become the heavy favorite over the entire field.

Ungar's technical mastery extended beyond poker into blackjack card counting. In 1977, he won a $100,000 bet by correctly identifying the last three decks of a half-counted six-deck shoe. While his skills were natural, they led to frequent casino bans and a costly legal battle in 1982 over allegations of 'capping' bets—a charge he fought in court to avoid admitting any wrongdoing.
