I raise JTs to 75 CO, SB 3b to 225, I call. I start hand with about 3500, he has 10k+.

Villain is youngish (probably upper 20s). He hadn't been at table that long, and sat down with $10k+ (no max buyin table). I didn't have much of a sense of how good he was. He open-folded a few buttons and limped several times/seemed pretty passive in general. But I overheard him talking about how "player X didn't bluff/get paid off with value hands" etc., so he was probably ok.

He had 3b bigger in a prior hand (I think to 400 from blinds after a 75 raise and flat), so he definitely varies his 3b sizing. I am assuming his relatively small oop 3b in this hand is likely a stronger range.

Flop is T62r, he bets 350 (into 475), I call.

Turn 2, he bets 850 into 1175.

On one hand, seems exploitable to fold with TP here in standard 3b pot, and if he has any sort of air in his range then I have his range crushed. But I also have about what it looks like I have, and he likely wouldn't expect me to nitfold TP here.
