AA in PLHE

[Riverman]

Same game as my previous post, 10-15 blinds, pot limit at the Borgata. A tight-agressive good player open raises for 60. All fold to me in MP. I have AA and just call. One additional caller behind me, then the button raises the pot. He is a very good player, and there is a fair range of hands with which he would make this move, though it will usually be a pair (roughly 88-AA). Anyway, original raiser mucks and it's back to me. My stack is about 1900 and the button has me covered. What's my play?
