Sorry no hand history

I have $262, villian covers

villian is listed as a 18/4 with over 100 hands on him. He has been playing tight but he has over $300 so he has a decent stack, I haven't seen him do anything crazy

Villian raises to $10 UTG, I call on the button with T[h] T[s]

He is the only caller (pot is $20)

Flop is Q[d] T[c] 3[d]

he checks, I bet $20, he calls (pot is now $60)

Turn is a 8[h]

He checks, i bet $56, he calls. (pot is now $172)

River is a K[c]

He checks, I have $176 left (he covers)

questions
1. what do you bet on the river and why?
2. Do you fear QQ, KK here?
3. What the hell does he have? (I just didn't think he had a flush draw for some reason)

maybe this is a standard hand but I think I will get a wide variety of comments on it

thanks

Check !!

I fear alot and so does he. He only calls you when your beat.
A guy with these numbers is not calling a semi good hand. Nothing to gain by betting IMO.

I bet $176.

I already saw results, but before I did my response was going to be:

I agree with Xaston, which doesnt happen often.

I wouldve never put him on KQ though. He only raises 4% of his hands but raises KQ UTG? And then check/calls every street with TP and a flush draw on the board? Very strange.

Basically there was very little chance he had QQ or KK, therefore I dont care what he has.....Im all in.

[Jd] was the only hand worrying me but I cant believe he would check the river if thats what he had.
