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.

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.

Mike A. Caro (born May 16, 1944 in Joplin, MO) is a professional poker player, pioneer poker theorist, author of poker books, and casino executive.

In 1978 he contributed 50 statistical tables to Doyle Brunson's Super/System and wrote that book's chapter on draw poker. He acts as a consultant to many casinos, providing odds, and he helped develop the Poker Probe, the first serious commercial PC program for analyzing poker situations. He is the founder of the Mike Caro University of Poker, Gaming and Life Strategy, the world's first permanent poker school. He was one of the few people who believed in the 1990s that real money online poker would work (most people said it would not).^{[citation needed]}

Caro is the author of a number of books about poker, including:

He also has made multiple videos, some of which correspond to his books. He was formerly editor in chief of Poker Player magazine and senior editor of Gambling Times magazine.

Mike Caro coined the famous poker tells "Weak means Strong" and "Strong means Weak", meaning that players will try to fool other players by acting the opposite way of the true strength of their poker hand.

Jason McCabe Calacanis (born November 28, 1970) is an American Internet entrepreneur and blogger. His first company was part of the dot-com era in New York, and his second venture, Weblogs, Inc., capitalized on the growth of blogs before being sold to AOL.

Calacanis was born in Bay Ridge, Brooklyn, New York. He graduated from Xaverian High School in 1988. He then attended Fordham University, where he majored in psychology.

During the dot-com boom, Calacanis was active in New York's Silicon Alley community and in 1996 began producing a publication known as the Silicon Alley Reporter. Originally a 16-page photocopied newsletter, as its popularity grew it expanded into a 300-page magazine, with a sister publication called the Digital Coast Reporter for the West Coast. Calacanis's tireless socializing earned him a nickname as the "yearbook editor" of the Silicon Alley community. With the end of the Dot-com bubble, Silicon Alley Reporter failed.

Calacanis co-founded Weblogs, Inc. with Brian Alvey in 2003, supported by an angel investment from Mark Cuban. Time Warner's America Online agreed to buy Weblogs, Inc. in October 2005 for $25–30 million.

Phillip Dennis "Phil" Ivey Jr. (born February 1, 1976) is an American professional poker player who has won eight World Series of Poker bracelets, one World Poker Tour title and appeared at nine World Poker Tour final tables. Ivey is regarded by numerous poker observers and contemporaries as the best all-around player in the world today.

Ivey first began to develop his poker skills by playing against co-workers at a New Brunswick, New Jersey telemarketing firm in the late 1990s. One of his nicknames, "No Home Jerome", stems from the ID card he secured to practice in Atlantic City, New Jersey in his teenage years. His other nickname is 'the Tiger Woods of Poker'.

As of 2012^[update], his total live tournament winnings exceed $16,000,000. $5,294,840 of his total winnings have come from cashes at the WSOP. He is currently ranked 2nd on the all time money list behind Erik Seidel.

Ivey's tournament accomplishments include winning three bracelets at the 2002 World Series of Poker, tying Phil Hellmuth Jr, Ted Forrest, and Puggy Pearson for most tournament wins in a single year (Jeff Lisandro has also since tied the record). Ivey also has bracelets in Pot Limit Omaha from 2000 and 2005. In 2000, he was the first person to defeat Amarillo Slim heads-up at a WSOP final table. In addition to his eight World Series bracelets, Ivey has had great success in the WSOP Main Event. He placed in the top 25 four times between the 2002 World Series of Poker and the 2009 World Series of Poker. Ivey finished 23rd in 2002, 10th in 2003, 20th in 2005 and 7th in 2009.
