Quick Question: low limit

[PShabi]

If you're in the big blind, the first guy in raises, and everyone else, including the small blind folds, what are your requirements to call that bet?

Sometimes, I think, call and try to out play him with your 9 10 offsuit. I guess for me, if I have a good read on the player and what they would raise with in early position, I make a decision based on that.

If you don't know anything though, what are your hand requirements to play?
