playing against nit so far 18/17 after 100hands.

I 3b pf in this spot 67s-KQs, KTs+, AJ, ATs, QQ+, AK. What do you think about this range?

Gameplan: I dont think so theres valuebet against nit on this flop. he's usually PP and broadawy heavy so I let him bluff with his broadways.

River? I like folding:
1. He's a nit. Nits usually dont 3barrel bluff.
2. People usually on this stakes dont 3barell bluff enough.
3. I block some of his bluffing range.
4. It's not a scarry card, that I would fold.
5. He still has JJ+ in his range since he's a nit.

My xc range is like Tx with daimond, KK+ with diamond. What do you think about xc QQ with daimond?
So I xc there 6combos, and xf 3-4 combos.
EV+ call would be if he call PF hands like QJs, KJs and bet all of his bluffs 3 times. I dont think so he does that.
