RIPTrippers

Hi everyone, first post on RIO. I've been going through the Ground Up PLO course (loving it) and playing and ran into this spot. For some reason, I can't get past my impasse.

I've played a thousand+ hands against Villain, but I don't trust my HUD against him anymore, he's shown vast improvement over the past couple months. He used to be a whale, and now I think he's capable of CRAI this river. He's also capable of folding rivers to 3-barrels from a strong range (which happened earlier in the session).

I realize I'm blocking QJTX wraps on the turn, but what calls a pot sized raise on the turn and a river bet on that rundown (QJTX hits)?
Am I bet calling? Bet folding? If so, sizing considerations?

My in game thought was between 1/3, 1/2, and check. I obviously settled on check, which seems criminal, but I can't put him on a calling hand with QJTX hitting. If he's still got on aggro-whale in him, do we go with 1/3 with the intention of calling?

I'd love to hear some thoughts.

Thanks
