So he's repping the nuts

Idk what's the best play on the turn here. Villain is a higher stakes reg, 27/20/2.4, not too positionally aware/splashy preflop. Again not much history.

My perceived range here is prob QT, FD, KT, 8T, Jx, 2pr. How do I proceed 150bb deep here?

Gonna add another hand so I don't start too many threads. 30/22/1.6, opens 16% utg, cbets 68%. I honestly have no idea wtf this is. I even have Th blocker to ThXh that would c/c flop. Fold cuz people don't bluff here, or call cuz he doesn't rep much?
