Villian is an older male on the tight side. Just sat down half an hour ago so no reads on post flop tendencies.

2/3/5 with a 750 effective stacks.
MP opens up to 15, HJ calls, I call on BU with K8hh, BB calls.

A bit on the loose side but with small open size and position I decide to call.

Flop: KdQd8c
MP bets 20, HJ calls, I raise to 80, MP folds, HJ calls.

Standard raise on a board with a lot of draws.

Turn: As
HJ checks, I bet 120, he calls.

This is an interesting spot, obviously J10 gets there. I chose to bet because a lot of nut flush draws now have top pair and I want to get value from those hands. Since V is pretty tight he only has 4 combos of J10s vs AJdd, A10dd, A5-A2dd. I also plan on checking back the most rivers if called. I also bet smaller so I can consider folding if raised.

River: Kc
HJ checks, I jam for 500, he folds.

OTR I considered betting small (150ish) to try and get value from top pair or go large and try to get called by J10. I don't think V has any hands that beat us. AK would 3bet and KQ would most likely raise on a draw heavy flop. I decide to go for a polarizing bet size to get called by strong hands and bluff catchers. I think there's very little in value in betting a normal size because his medium strength hands like K10s and K9s are heavily blocked.

Interested in hearing what everyone else thinks esp about the river sizing.

Fold pre.

Flop isnt that standard. Prefer a flat. Your equity vs stack-off ranges suck

Turn i guess is standard bet/fold 4-way to the flop.

River seems fine. I'd prefer 85-95% pot. Just think a slight overbet AI might make him fold Kx on occasion, esp his weaker Kx like K2s-K7s

He literally never has JT

Pre is meh, if MP is loose/bad it's probably ok but i'd prefer a 3bet in that case.

Flop: vs an 1/3 pot bet raising is fine. I'd go slightly bigger even. It's not like JT/Ahxh are folding are folding often, so let's charge them.

Turn: yeah b/f seems fine. After he flats i wouldn't expect him to have JT often, perhaps specifically JhTh.

River: You are right, his Kx are heavily blocked and most of his strong hands like KQ, 88 or JT raise before the river. So yeah some of the time villain calls your overbet because he played his strong hands badly, but most of the time he has a marginal hand which he instafolds. Heck he might fold KT and KJ anyway vs that sizing.

Bet small, get hero'd by Ahxh imo.

Fold or 3bet pre (but 99.9% fold pre)

I'd go for a small size OTR, 150 about right probably. I don't see how he ever has a hand strong enough to call and bluffcatching would be pretty ******ed, if you look at our line it's basically impossible for us to have a bluff. I'm going to hope he has something he wants to call with so he can complain about how unlucky he is, AJdd or something would do nicely.

Rest of the hand looks fine.

Pre I'm really fine with anything. Threebet might be best. Call and fold are both fine as well.

Yeah let's just allow him to be directly priced in on this obvious flush draw. that's what this bet size means if he isn't good enough to induce with some of his stronger holdings. I would raise to larger than 80 here fwiw.

As played our hand just looks too much like what it is by the time the river rolls around. Pretty likely that he has an ace here and will call a more reasonably sized bet, but never calls a shove.

That's not how it works
