Doyle F. Brunson (born August 10, 1933) is an American professional poker player who has played professionally for over 50 years. He is the first two-time World Series of Poker main event champion to win consecutively, a Poker Hall of Fame inductee, and the author of several books on poker.

Brunson is the first player to earn $1 million in poker tournaments and has won ten World Series of Poker bracelets throughout his career, tied with Johnny Chan for second all-time, one behind Phil Hellmuth's eleven. He is also one of only four players to have won the Main Event at the World Series of Poker multiple times, which he did in 1976 and 1977. He is also one of only two players, along with Bill Boyd, to have won bracelets at the WSOP in four consecutive years. In addition, he is the first of five players to win both the WSOP Main Event and a World Poker Tour title. In January 2006, Bluff Magazine voted Brunson the #1 most influential force in the world of poker.

Brunson was born in Longworth, Fisher County, Texas, a town with a population of approximately 100, and was one of three children. Because of Longworth's small size, Brunson frequently ran long distances to other towns, and became a promising athlete. He was part of the All-State Texas basketball team, and practiced the one-mile run to keep in shape in the off-season. Although he was more interested in basketball than running, he entered the 1950 Texas Interscholastic Track Meet and won the one-mile event with a time of 4:43. Despite receiving offers from many colleges, he attended Hardin-Simmons University in Abilene, Texas, because it was close to his home.

Christopher Philip Ferguson (born on April 11, 1963) is an American professional poker player.

He has won five World Series of Poker events, including the 2000 WSOP Main Event, and the 2008 NBC National Heads-Up Poker Championship.

On September 20, 2011, the U.S. Justice Department filed a motion to amend a civil complaint, alleging that Ferguson and three other directors of the poker website Full Tilt Poker were running a Ponzi scheme that paid out $444 million of customer money to themselves and the firm's owners.

Ferguson was born in Los Angeles, California. Both Ferguson's parents have doctoral degrees in mathematics and his father, Thomas Ferguson, teaches game theory and theoretical probability at UCLA.

Ferguson attended UCLA where he earned a Ph.D. in computer science (focusing on virtual network algorithms) in 1999 after five years as an undergraduate and 13 years as a graduate student. His Ph.D. advisor was Leonard Kleinrock.

Ferguson began playing poker at the age 10. In college he honed his skill on IRC playing poker for play money in chat rooms. In 1994, he began playing in tournaments in California and in 1995, he entered his first World Series of Poker. Ferguson beat T. J. Cloutier at the main event of the 2000 WSOP to win the $1.5 million prize. In 2004, he entered the WSOP main event, earning $120,000 for his 26th place finish (out of 2,576 players). Also in 2004, Ferguson helped launch the online poker site Full Tilt Poker.

Daniel Negreanu (pronounced /nɨˈɡrɑːnoʊ/; born July 26, 1974) is a Canadian professional poker player of Romanian origin. He has won four World Series of Poker bracelets and two World Poker Tour Championship titles. He is currently ranked second in the all-time career earnings list and is the star of poker game show Million Dollar Challenge. He plays a big part in the Pokerstars.net Big Game.

Negreanu was born in Toronto, Ontario. In 1967, his parents, Annie and Constantin, emigrated from Communist Romania, hoping to start a new life in the United States. Instead, they ended up settling in Toronto, where Constantin worked as an electrician and sold confectionery. Daniel was born five years after his brother, and even at an early age was extremely ambitious. "From the age of four, I thought I’d be rich. I told my mom I’d build a house out of Popsicle sticks, and move to Cafornia (sic),” Daniel recalls in a 2009 interview.

Daniel Negreanu attended Pineway public middle school in North York, where the principal complained to his mother about Daniel's "poor manners or behavior" and threatened to expel him for "ignoring the school rules." While nursing dreams of a career as a professional snooker player, the now 15-year-old Daniel learned how to play poker. By 16, he was spending time in pool halls, hustling, sports betting, and playing cards. When he was several credits short of graduation Daniel dropped out of high school and began his life as a rounder playing at the local charity casinos, usually at Casino Country and Fundtime Games, and looking for illegal games around the city. While in Toronto, Daniel met and began dating Evelyn Ng, who would also become a well-known professional poker player. After building up his bankroll, he left for Las Vegas at the age of 22 to pursue his dream of becoming a professional poker player. However, "The Strip" got the better of him and he was forced to move back home to Toronto to rebuild his bankroll.
