The only advice I can give is play VERY tight...tighter than you would in any poker game. If the blinds are small, I try to wait 'til I have a ready-made hand to play...or close to one. And if you aren't getting any hands, you will be able to make people think you've got one because they will see you have been playing tight. Oh, and you should also watch how many cards people are drawing too to tell if they have a pair, trips, flush/straight draw, etc...but thats a given.
I played with someone one time that would raise before the draw and then only draw two cards every time he had a pair to make people think he had trips...It worked very well for him, and he was high up in the tournament rankings...until he got caught. lol
