Post Flop vs. a PFR

[mblax10]

Hands like this one in the middle of MTT are killing me.

Stars L7 (100/200/25)
Villan has ~T10,000 was chip leader but just took a beat for ~9,000. Has been opening 2-3 times an orbit with little resistance.
Hero has ~T6,000 (just under average)

Villian opens in MP to T600, folded to Hero in SB with [7 [img]/images/graemlins/heart.gif[/img] 7 [img]/images/graemlins/club.gif[/img]]

What's Hero's action?

Come over the top?
Stop and Go?
Call and fold if I don't hit the flop?

Looking through recent HH, I need lots of help with my post-flop play, especially vs. a raiser and would appreciate some help. What's my action if I have AQ?
