i cant agree more that at this 1-2 nl level, it's really dependent on your opponent's playing style. if he is LAGG, who likes to raise any drawing hands, just push over all-in right on the flop. Otherwise, i'd flat call, re-evaluate on the turn and fold to his all-in or very huge bet . If checked to, i definitely push all-in and put him in difficult situation
playing aggressively with AA is the best way to make more money in the long run.
