Many reside gamers don't consider large blinds, they only think about chips. What I mean by that is if for example, at a $1/$2 game, someone raises $6, many gamers will think "oh that's just 1 red chip" instead of considering of three large blinds. If you're going to come in for a raise in a live game, you'll most likely want to increase between 6-8bb, at least in the $200NL live sport.
