Hypothetical hand question

[iheartponeez]

So here's my hypothetical dilemma. Since it hasn't happened yet, I don't have stats or anything, but say you are UTG in a 6-handed game, you've all got 100BB stacks. You have A7s, you limp with it. The CO raises up to 4BB, and you call. Flop comes A 9 4, with no flush draw for you. I guess you can put the villain's range on broadway hands, 88-AA, and maybe some SCs? How do you play this? Check/raise/fold to a reraise? Just a pretty basic question I have.
