ONLINE POKER - SITE - Party Poker

Has anyone else noticed that when you first sign up, you tend to "catch" a lot more cards than you do after you've been playing for a while? I've noticed that at the beginning, I would catch inside straights and flushes a lot. Almost as if they are trying to program your mind into thinking that you're going to catch those cards everytime you have that draw. After a while, you never catch those cards. You run up your bankroll only to eventually lose it. Then you think, hey, I was once ahead, I can do it again, so you deposit more money only to lose it again, even after tightening up your game. I, and others I've talked to, have seen this trend, not just on party poker but other sites as well.
