You already gave thoughts about villains bluffingrange OTF. What do you expect villain to bluff the flop and XF the river that beats you?
Imo we have decent SDV and there is no need to bluff this one.

RaoulFlush Doesn't matter if Hero has x amount of bluffs in his range or not. In regards of valuebetting or checking is more EV OTR. This is exactly a spot what I was referring to before, when I said there are spots at smaller stakes where people mess up the thought process with trying to implement some kind of solver/gto based stuff.

The only thing that matters is villain's range OTR and what he's gonna call with. He's not gonna think about our range in the classic way, in the same way as a reg does, therefore how we play the rest of our hands here doesn't matter at all. His decision of calling or not will mostly be based on his own card and emotions. By emotions I mean a wide range of things like he could be the kind of player who has a huge ego and just can't fold any weak pair. Could be someone who is always afraid of the better hand so folds stronger hands (not too common). Could be an emotion based on previous experience like winning a big pot with a bluffcatch a week ago, that's gonna be a positive emotion paired with calling light... You get what I mean.

Point is he's not gonna consider our range in a classic way but rather based on his own emotions and stuff that happened to him in the past and how he usually interprets those things. Everything considered, fish is gonna call you pretty light most of the times.

I like the idea of this valuebet, I play it exactly the same. Wouldn't say it's super easy, feels kind of close but the idea itself and that Hero is thinking about this is a very very good thing. Whether or not in this exact case it'll be a small +EV or BE or a small -EV, I don't think that matters and it's also hard to say. I feel like it can be a small +EV.

hmmmmm...i agree partly on what you say. Because even if villain doesnt think about heros range, villains callingrange will still be elastic here. So the fact that we isolate ourselves vs a stronger range with a bigger bet will still happen naturaly cause even weaker players fold more vs bigger bets.
You are right that this decision might be influenced by emotions or the weather or whatever, but this can go one way or the other about his decision making.
So im still not a fan of pot size shove otr.

While I like the justification for a thin bet above and I like that we're talking about it a lot, I think the bet is a bit over the edge here.

With the turn bet, I think we can think of the villain's range as fairly full of value bets, including hands he is protecting too thin like TT or 99. Much of what he would semibluff got there, excluding KhXh, which he may continue to semibluff.

The river is a blank and he checks. Now there's no question a queen or better is calling. The question is, will a jack, nines or tens/ And if so, how many are in his range?
-made hands - a few (sets, straights, Q9, QJ)
-queens in his range - plenty(AQ, KQ, QT, we'll throw in a "fun factor" of say Q7s and Q5s of the heart also)
-jacks in his range (All AJ, KJ, JT, some J9)
-underpairs - a few (99,TT, and deuces because deuces are lucky)
-missed draws

Excluding the draws, we're a slight dog to this range and I don't think we're folding out the better hands. I don't think he'd look us up without an ace and we have the ace he'd draw with.

I think it's a check.
