PokerStars has slightly less fish... but why in god's name do you want people who play better? Your money comes from people who suck more than you (paraphrased from Fnord, no offense). Just so you know, backdoor does not mean rivered, backdoor means runner runner. A set usually has 10 good outs to make a full house on the turn. A flush draw has 9. You're playing .25/.50 NL right? You'd be eaten alive at higher stakes if you were thinking of moving up to avoid bad beats. If you know someone will take their low PPs to the end, don't bluff. Only bluff the bluffable. Re-evaluate your game, don't knock the players that are ATMs for the rest of us. That'll make them get better and take your money consistently... end rant
