The only thing I can tell is to play tight and play even tighter at the lower limits. It's tough to bluff a new player off of a $0.50 pot at very low levels. Maybe it's just me but I see a lot of chasing and loose calls even at $1/$2 NLH which is pretty high stakes for me. It's great when they miss but Hell when they don't. I don't play any differently online than I do live. I just pay attention to table selection and you can get all the information you need about that in the book you don't want to read.
