well as to player retention:
I finally got tired of losing to inferior hands on such a consistent basis. After having moved (back) to cryptologic’s poker room I am doing much better and I see SO many fewer bad beats its amazing.
PP claims their software is random but I got to tell you that i am not the only person that believes there are way too many bad beats at PP. This will drive a lot of “play on regular basis” poker players away because eventually they all get smart and start just playing the premium hands, and once you do that it doesn’t take very long to come to the conclusion that the inferior hand wins on the turn or the river way too damn often at PP.
especially if you compare it to playing at home or for that matter many other online poker rooms as well.
so IMHO PP needs to fix the ‘bad beat” phenomenom if they’re truly dedicated to player retention.
