You try to get the best low starting hand. Generally you do not want to be playing unless all 3 of your first cards are unique and 8 or less (ace is the lowest -- think of it as 1).
Do a search for razz here and see what turns up, or search for my personal posts since I try to give some input anywhere I see Razz being mentioned.
I play razz almost exclusively, and can assure you that you can win a nice chunk of change if you know what you're doing.
