Yes, the 20/40 games have many pros. They also have many 2+2ers who may have day jobs, but play at a pro level. However, there are also many weak and inexperienced players who have a lot of money, especially on the weekends. The trade off of going up against the pros is worth it, if you can select the tables with the poorest quality players.

20/40 is a much tougher level than the 10/20. There is usually at least one raise pre-flop in the 20/40 as compared to the not raised preflop play with four callers in the 10/20. Most hands are contested heads up or three way max in the 20/40, versus the free for all at the 10/20 game. Also there is much more semi-bluffing on the flop and the turn.

I don't know about any collusion, I haven't seen any and I put in over 100 hours at 20/40. I know I have sniffed some out in the Taj and reported it, and they got right on top of those players. I know if I detected collusion at the Borgata I would report it. I would also believe a lot of the pros would detect it and report it as well. The pros don't depend upon collusion, and it would only hurt their livelihood.
