Oh you can raise your AA 4 times the BB and sometimes you'll get callers but more often that not (and I've been playing a LOT of hands on .05/.10 lately) if you raise it up to say .50 cents you're going to win .15 cents (bb and sb) from the hand and not get any action at all...I'm not saying to limp in with this hand I'm just saying that your actions on a small table are absolutely different than they would be on a $1/$2 table...
