I've played a bit and it can be frustrating.
There have been a few times when I am in first (you only know position and not how far ahead you are) when the final hand is dealt (There are a predetermined number of hands) and end up in 2nd or 3rd (only 1st at each seat wins) cause of alot of desperate allins from the 2nd/3rd place players at the other tables.
All in all (no pun intended) I seems like a neat idea. How far it will go remains to be seen.
Oh and
Duplicate Poker will give you some free $ to try it out.
