Dennis Phillips was beaten by a woman in a latest poker tournament. Duke faced one of the toughest roads in the bracket competition, starting off with a win over Andy Bloch. She then defeated 2009 World Series of Poker Main Event runner up Darvin Moon to reach a showdown with the 2007 champion of the Heads Up event, Paul Wasicka. After defeating Paul, Annie dueled against 2007 WSOP Main Event champion Jerry Yang in the Elite Eight.
Duke was able to defeat Yang, setting up a showdown against 2008 WSOP Main Event third place finisher Dennis Phillips. Once she took down Phillips, Annie faced perhaps her toughest challenger of all in her good friend, Erik Seidel. Things started well for Duke, winning the first of the best of three match, only to see Seidel tie the event up in the next game. After a frantic third match, with neither player able to eliminate the other over several all ins, Annie was finally able to defeat the 2010 Poker Hall of Fame inductee and take home the $500,000 payday.
