Villain is a 20/18/8 after 160 hands player. Flop is a range bet for me, turn I'm less sure about, but figured I have some equity, and won't have too many better straight draws to bet (QTs, but 65s and 76s aren't in range very often). Otr, I unblock flush draws from the turn, as well as blocking KQs (assuming villain doesn't call KQo), so I figured I couldn't go too badly wrong. Any thoughts?

flop is a range bet for sure. its textbook. our range advantage maintains its preservation throughout this hand, you could go bet bet bet in theory but these stakes people dont continue with correct number of combos (they overfold).
turn large sizing is absolutely fine - (if you think of it as making up for lost time/value when we range small on flop, our value hands are gonna want to size up here and thus also our bluffs). you go actually go larger.
river is a mix between give ups and big bets - overtime your judgement as a frequent player at these stakes will know the answer. no clubs and blocking KQ is totally fine in theory, just gotta feel these out for yourself just how nitty these overfolds are street by street. im forever an optimist and would bet here but its not as +EV as it should be for sure.
hope this helps.

Not sure I understand the logic of bluffing this river.

We're targeting weak pairs that will mostly fold on the turn so V's range is pretty strong on a blank.

what are your river bluffs in this spot?

This. Feels like we pretty much have to bluff here due to lack of other bluff combos

I figured I had some value bets, AK, KJ, AA, KK, maybe KQ, so I thought I needed some bluffs. Plus, I felt like I could get some folds out of AJ, maybe QJs, if villain is nitty (but loose pre) maybe even some KTs or K9s. And flush draws.

It's hard if you see mp cold calling vs utg, it's hard to assign villain ranges, "intuitive" range would be non nut broaways and pp's, maybe axs, so i think we should give up now, dry flop and dryish turn, so villain can slowpaly weak set here, can have kj in range, if i ever want to bluff now i would make huge overbet, but preffer giving up readless

Are you betting KK here? Yes. How much? If you're betting big (even betting small), you need to have bluffs. So what are they?

I think the difference here is people think if we have a value-range we automatically should have bluffs @ micros.

Fine against a gto opponent but actually counterproductive agianst a station. MP called pre, so is likely a fish, so we'll just get called way to often to neutralise any nut adv.

Any EV we lose with our unbalanced value hands we make up for by betting thinner, e.g. KTo for 33pot to get a station to call Jx or weaker kings. This will happen more often and more profitably than V folding those hands to our bluffs.

The problem with that line of logic is that it assumes all fish play the same way. Some call too much. Some fold too much.

I agree that we have to exploit the stationy nature of some of the players, and this is something I don't do enough of. So, its definitely worth going for thin value I think.

Thanks for the feedback everyone. I ended up going for the 3/4 pot third barrel, and villain called with JJ. Have to say, I was gobsmacked to see that. Couldn't quite grasp why that wasn't raised pre, Ott, or otr.
