If you're playing tight, especially in a short-handed game, then you should forget about an early position raise—everyone will fold. You have to limp. Ideally, someone raises, and then you can re-raise, and take down a sizeable pot, then and there.
All AA does for you is give you the best hand, pre-flop. The more cards laid down, the less likely your hand is to be best. Because all that you have is a pair. Your best chance of improving is a set; which is very unlikely.
Build the pot, pre-flop. Make inferior holdings fold. Post-flop, if you don't improve, then cease building the pot. If you're out of position, and there are lots of draws on the board, then you're short on luck. Cards are nice, but position is king.
