Las Vegas is the scene for the 39th annual World Series of Poker currently running but there are more reasons to play poker in Sin City than gambling. The Ante Up for Africa event is organized by poker pro Annie Duke and Hollywood star Don Cheadle, and is drawing plenty of attention to the crisis in Darfur. One player who is signed up to participate some think should not is Charles Barkley, former NBA star who pledged to end his gambling ways. Barkley says he plans to play anyway, because the event is for charity.
