AJo, should I bet out on A high board?

[Airharley]

Ok, 4/180 on Stars, after the first break, about 35 left or so. Just moved to a new table so no reads. Sorry no converter I'll do my best. 200/400 blinds with some sort of ante, 25 I think it is.

Stacks, most at the table have about 5-6k or so. A couple bigger stacks, Hero ~10K not really big, but 12th in chips I think. Villain ~13K or so.

UTG limps,
Hero is MP with AJo and limps (should I raise here or fold?)
Villain is HJ and raises to 1000
UTG calls, Hero calls

Flop 37Ar
UTG checks, Hero???

Should I bet out at this or should I check with intent to either call or raise?

comments on all streets appreciated.

I probably check/call the flop.

I don't like limp/calling AJo, but you are priced in. I think I would fold to the small raise with this hand, since it is so hard to make a big hand with AJo. Of course no one would make that fold in a $4/180. Any reads on the small raise? Does he have a big hand, is he building the pot with position, or does he not know how much to raise.

Initially, limping, raising, or folding are all OK.
