Like the others have said, 3bet pre-flop, this will significantly improve your equity in the hand.
IF you don't 3bet pre-flop, what are you going to do post-flop if you hit or miss? Your fold equity is usually pretty low if you've missed, OOP, having just called pre-flop. Playing fit or fold is bad because you will miss most of the time, so we want to avoid this. Also, when you do hit, you're usually going to win a much smaller pot than if you had 3bet pre-flop because the pot size would be bigger, so bets are bigger, plus you wont have to essentially turn your cards up by the time you get stacks in - which you would have to do after calling pre-flop.
If you 3bet, you have equity pre-flop because most of the time you're taking the pot down right then and there (which isn't really a good thing with a premium hand, but being OOP destroys your ability to gain value post-flop so we have to remember AKs OOP is really, really diferent to AKs in position).
When you do see a flop, you're still getting equity vs most A's and K's, which will be more than if the pot was smaller when the flop was dealt.
Plus, when you miss, provided that you bet flop and turn with a reasonable frequency (dependent on how often your opponent will float your flop bet), you've got a ton of fold equity against smaller pairs.
Sorry if I'm just stating the obvious, but I'm guessing that to make the pre-flop call you have to just not know some or all of this.
