Poker career
In May 2001, Seif quit practicing law to play poker full-time. In August 2002, he was one of six finalists at the inaugural World Poker Tour World Poker Tour (WPT) Legends of Poker Championship in Los Angeles, California at the Bicycle Club Casino. Seif finished in fourth place in that tournament that was broadcast several months later across the United States and later internationally.
Seif is best known for being the only player to win two WSOP bracelets in back-to-back events in 2005 in the $1,500 limit hold'em shootout and the $1,500 no limit hold'em events. He bested a field of 2,013 players to win his second bracelet at a final table that included poker professionals Minh Nguyen, Greg Raymer, Dave Ulliott, and Bill Gazes among others.
In 2007, Seif purchased a US Poker Bowl franchise named the Detroit Absolute Nuts, who went on to win the first ever US Poker Bowl Conference Championship.
Seif was a color commentator for the Professional Poker Tour television series which aired on the Travel Channel starting in July 2006 and ended in late 2009. He has been a spokesperson for Absolute Poker since 2004. It is estimated Seif earned in excess of $2 million per year as the public face of Absolutepoker.com, one of the biggest and highest revenue online poker sites in the world until April 15, 2011, when the US Government seized the domain names of the three leading online poker sites including Absolutepoker.com, Fulltiltpoker.com and Pokerstars.com forcing the poker sites to permanently shut down US operations. Several years later, Pokerstars.com re-entered the US market in the state of New Jersey, but with limited success.
As of 2023, Seif’s total live tournament winnings exceed $3.1 million.[5] His 26 cashes at the WSOP account for $1,086,415 of those winnings.[6]
