If i have AKs or AQs and i'm out of position i usually will play it agressively pre flop and post flop if i feel that i know my opponent well enough. If the flop comes rags with only 1 of your suit, and you bet half the pot and get called and pick up a 4th of your suit on the turn? You have a pretty well disguised hand for a semi bluff. What would your opponent smooth call your flop bet with? If he has a decent hand you're definitely going to get paid off if you make your hand on the river.
