HH converter on this site keeps telling me 'Invalid Hand' so posted it on weaktight.

Villain is only opening about 50% in position and calling 50% of 3bets. I'm 3betting 15%.
Haven't seen him get out of line and so far at showdown he's been winning a lot. He's checkraised pot on the turn a few times repping the nuts that I have not seen shown down.

Is this an easy fold on the turn and I'm overthinking it? What hands would you play this way in villain's spot? Any thoughts would be helpful, thanks.
