I bomb JJ in blinds preflop and this stupid TAG won't fold

[goofyballer]

Villain is 22/14/4.3 over good sample. We haven't tangled too much, seems like he's been playing somewhat weak-ish so far. We've 3bet each other a couple times but the other person has always folded.

I two-barreled because I figure that given my nitty stats (which he should be noticing, being on a few tables w/ me) he should be folding almost any one pair hand on the turn, although it's hard to put him on one pair at that point anyway (is he limping 88 UTG? AQ?). So given that it's hard to put him on pretty much anything...what do I do on the river?
