How good is an underboat in this game?

[elitegimp]

Thanks for the replies everyone. I guess I was still stuck in a hold 'em mentality, where any pair is worth playing in hopes of flopping a set. Suppose I have a hand like this one, a pair and some low cards. How big of a pair or how should the low cards be before I consider playing? Or, better yet, what's a good resource for pre-flop O/8 play?
