JJ vs. thac - NL$100

[AZplaya]

Decided to post this here instead of SSNL because I seem to get more responses here.
Villian is thac. I have him at 17/14 over about 450 hands, he seems to play fairly straight forward abc tag. Only history is a few small pots and then he stacked me when I got KQ all in on a J10x flop against his J10(lol whoops).
No HH cuz I'm at work.

Right around $21 in the pot - bet fold, check call or check fold, and why?
