1/2 NL, effective stack $600, 5 handed. Villain is a pretty wide. I'd say he's ~VPIP 60% and PFR 30%. Hero and villain have a lot of history and he definitely views hero as a strong TAG. Villain tried to 2.5x bluff hero earlier on a board that made no sense and hero called with second pair.

OTTH

Villain limps UTG and it's folded to hero in SB with K T who raises to $15 and only villain calls.

Flop ($32): T 8 8. Hero bets $15 and villain calls.

Turn ($62): K. Hero bets $30 and villain calls.

River ($122): J. Hero bets $50 and villain raises to $200. Hero? Thoughts on betting the river and sizing?

Not sure about river, do you think he will sigh call with one pair? By the turn he's got quite a bit of 8x and 97, and stuff you beat like Tx, QJ, etc probably isn't going to pay off. Probably just checking river.

Turn I'd go bigger too

He's 100% sigh calling with J9 and JT, and more often than not with AT/QT. What do you do in response to the raise, as played?

What's your reasoning for betting bigger on the turn? Narrows his range if he calls, and gives us easy river check-call?

If he's sigh calling all those hands then he doesn't have any bluffs and you should fold. You were there and know him better so I'm not going to doubt he sigh calls them if that's your read. But it is pretty bad of him to call those hands.

Turn bigger reasoning is for value, I think he can profitably call too many hands vs this size.

He could potentially turn a T or J into a bluff, but I'm not entirely sure. Maybe some random air that he was planning to bluff with on a later street, using K as scare card? When you put it like that though, definitely sounds like easy fold.

Im probably x/c the river.... Everything else seems fine tbh

b/f river on the smaller side with Kx and 2p
bet big with straights, AA and 8x, fold AA and the weaker 8x to a raise

You called!? Why?

For sure bet river, just fold now. He has zero bluffs.

Haven't looked at the results yet.

I would bet more on the flop and the turn.....for value.

Like the river bet. Now you have to fold since V raises. Looks a lot like 97, or 8x, many which are now boats. You said that Villain is pretty wide. So he could have T8 suited or J8 suited or K8 suited.

When players in 1/2 take passive actions preflop, flop, and turn, and then raises the river, it's rarely a bluff and V almost always has the goods. Two pair is rarely ever good here. I think the two most logical hands are 97 and T8. 97 got there on the river, and T8 flopped the boat and walked the dog.....waiting until the end to raise you. Your smallish bets on the flop, turn and river would signal to me that you don't have a boat, so V thinks his straight is good here.
