Yeah, but... You don't actually have unlimited tries. I'm not sure what the number is, but you have to hit 90% of the cards within x number of tries, or you're out.
I decided to try it again at an Omaha table. I made to to 80% then the table emptied out. So I'm sitting here waiting for some players to join the table so I can win that last hand that I need. I guess, assuming the table doesn't close out completely on me, I could wait around a few hours, to complete my 'unlimited' tries. But that seems pretty silly, if not downright dumb.
When it was down to two players - me and one other, I actually considered limping in to a hand rather than betting just to get the other guy to stay. But, I bet instead, and he shut down. So here I sit.
Of course on the positive side, I decided to check in to Cardschat while I was waiting.
Plus, say you win one for 10 cents. That's it for the day. You can't play again.
