Would never touch any site running iPoker again. Hard to say its rigged . Think its just the purely unbeliveable bad standard of play, even in $100 games I have mat some huge donkeys.
Worst example would be a heads up game for $100 had the other player all in & dominated after the flop. The table went down . When I enquired the result he amazingly got runner runner for the only 2 cards in the deck he could win with,,,,,
My recommendations would be PKR Full Tilt or Poker Stars
