i would agree with AOKrongly on this one - I will call 4x the BB with most pocket pairs, but if you are re-raised you can just let it go...No sense in taking 66 against a super tight ass rock...I would just let it go there...if he's that tight, he might not even pay off you set if you do hit it - players that tight can sometimes spot a set hunter and get away, although at 25NL they will call down just to show the AA and gripe about it
