50/100 AKs limped pot decision

[evanski]

I apologize if this is a super basic hand. I play very little >5handed poker and mostly play hu. As such, my perception of ranges in certain spots is likely pretty effed.

No stats on villain. IMO hes an average 50/100 player probably a bit on the nitty side, but certainly capable of bluffs/moves. Im probably (correctly) viewed as a bad LAG. Ive been reasonably active so far and got stacked once when I called a pfr from the bb with 56dd, floated a Kd3c2c flop and check shoved a Ad turn (got called by AJos, different villain).

Hand (9-handed):

UTG (Villain) limps, co limps, sb completes, I check AKs.

Flop AA7cc

I lead 350, utg calls, all else fold

Turn Jo

I lead 1050, villain raises to 3100, I? (~8.5k behind).
