WELL, I buy back in if i lose, and usually can make back what a lost and then some. Also, yes. My live competition is particularly weak, and because I know all the players I play with, I can adjust to each of their individual playing styles rather easily.

EDIT: Mostly I win live because I'm very good at judging when people are going to fold, and for how much. If they fold, the cards I get don't matter at all.
