Stars $5 re-buy. AA vs. Very loose player

[JoshNjuice]

Villain has been in a lot of pots. He's obviously limping constantly because he has a lot of chips. He doesn't seem particularly passive or aggressive.

Villain checks, Hero ???

I realize this probably seems standard to everyone. I'm going to ask for input on every street, but I want to get a consensus on what my play should be on the flop before I continue.

Thanks!
