Paradise is where I started playing online poker, I have had about equal success and failures there. I have had ALOT of bad beats, but that's gonna happen anywhere, whether or not there are more bad beats than there should be I don't know.
I think that most of the bad beats come from players playing hands they "shouldn't" not so much on what the software is.
For example the beat I took that stands out the most in my mind.
Playing a low limit game, I have pocket AA, I raise preflop, 2 people call. The flop comes no help to my hand but no scare cards (don't remember the exact flop). One player bets, I raise again another player calls, then the original bettor folds. The turn comes, is a 2, again based on whats on the board, not really a scare card, I bet, the next person person calls. The river comes, is an 8. Again, not much reason for me to think I am beat, I do only have AA but no flush or strt possibilities. I bet the other person raises, thinking maybe they hit trip 8s I just call instead of raise (have too much in the pot to bail incase they are just trying to take down the pot).
Turn the hands over, I have a pair of A's, they have 2 pair...8's and 2's. There is no way that person should have been in the hand. Calling a raise preflop with 8-2 isn't a good play, then to call another raise on the flop with no help at all, and yet again to call a bet with just bottom pair on the turn are just stupid plays. Granted any 2 cards can win, but there are just some cards you aren't "supposed" to play.
