Jerry Yang, a 39-year-old psychologist and social worker from southern California, has won the 2007 World Series of Poker Main Event at the Rio Hotel and Casino in Las Vegas.

Yang collects the biggest prize in world poker, $8.25 million in prize money, the coveted gold bracelet and the accolade of being No Limit Hold'em World Champion

Yang began the final table of nine with the second smallest stack, but managed to get a foothold, and then the chip lead and dominated from there.

The victory came at 3.48am local time. Yang bet his heads-up opponent Tuan Lam with pocket Eights, and Lam came all-in over the top holding A-Q suited.
