Yes, 3-4bb raise preflop, but if you on the late position 2bb but never just call bb (there is a chance that players with 28 or same hand can take a part in this hand and u wouldnt be pleased if flop will be 2A2 ). Than bet on flop. Checking wouldnt give you a profit, because u showed aggression preflop. Than if he called but thought it would be better to make a small bet or just not make him see the river!!

Having AA pre flop is big. You want to try to narrow the playing field down as low as possible. You want to try to play small pot poker with it because to many people lose to many chips with AA, so just be careful
