Wearing the same sweatshirt covered in his family’s painted handprints that he wore at the 2006 tournament, Mr. Einhorn was among the 3,400 competitors leaving Sin City at least $10,000 lighter (the buy-in for the Texas Hold ‘Em Championship tournament.) The tournament drew 6,865 players this year, among them the Boston Celtics star Paul Pierce, the actor Ray Romano and a host of former tournament champions. The winner gets $8.7 million.
Mr. Einhorn, one of the founders of Greenlight Capital, has an affinity for the card game. In 2006, he finished 18th in the tournament, earning more than $600,000, which he donated to charity. This is only his second time playing in the tournament.
