One thing you need to do is raise more often for information. Especially as you move up in higher cash games... you need to do more defining of your and your opponents hand a little early on.

Let's say on a pair board 8,8,3 you just smooth call a flop bet with 9,9...

What are you going to do when an Ace shows up on the turn or river... and an aggressive player.... who's figured you out makes a big beat?
