I played their generous free rolls a bunch of times. Those guys were easy, I always was able to get together over 10k in chips and I placed a couple times in my short stint.
Well, I dont know about Interpoker's live tables. But--
Ultimate bet had the most difficult players at the free rolls, and they are ranked high in difficulty @ RMT so perhaps there is a relation there after all.
Interpoker has a lot of bonuses and things all the time. Why not play at bodog? go hit up that 100k tourney Pat. Money checks out at double per player on what they invested. besides, theres a sportsbook there.
