Are we turning hand into bluff here?

Not sure I even bet this 4 ways

Pot control and check behind.

You have showdown value. Passive villain could be calling along with a flush and you’re not strong enough to bet and charge draws. The river card could change things in a lot of ways, so I’d wait and see what it brings before investing any more. You still get to see what villain does first after the river card.

Check behind: maybe bluff raise some rivers if they bring 4 card.

If he can fold a hand postflop, then yeah bluffing could be good. But it seems like we have much better hands bluff with, and much better hands to value bet. This hand doesn't really fit the criteria for either, so we should check.

If we were to bluff a hand, something like JTs or AJ seems better. That way there's more Qx for him to fold on the river.

Adding to illiterat's great points, it's a button straddle, and the tight, face-up V, first-to-act, just 3x'd. We're usually deader than chivalry here, and I want to fold, though I understand why you called.

If you think this tight player can make a "smart fold," I don't mind shipping turn. I think you're beat (giving V QQ+, AKhx, AQ), against which H is ~2-1 dog. Obv if your range perception is different, this'll be different.

H has 265 back, pot is 105. I guess H still has room to bet smaller, like pot, and hope that V doesn't come along. Or check back and try to bink.

Are there any high hand/BBJ promotions that might alter actions here?

In these small SPRs I typically want something a little more nuttish making. I mean, we're pretty much closing the action and will have position on everyone but the Button, and we have suited broadway, so I'm not gonna hate. But honestly I fold here in game most of the time. But I'm a nit and it's possible that is too nitty.

I think when it checks to me in position, especially when everyone else has checked after the preflop raiser (i.e. not as likely someone is sandbagging), I'm ok with a flop bet to see what happens.

Once that Villain with that range calls, I'm done with the hand UI. I typically don't attempt to get overpairs to fold unless my story makes far better sense, and he's never folding TP+ with a heart. Also, SPR is small; a lot of Villains won't have an exact knowledge of what that means, but a lot will shrug their shoulders and say "meh, pot's too big to fold".

Pre: I am squeezing this hand, our hand is way too good for us to not 3bet here. Plus us calling makes it more likely for the BTN to call, we are incentivized to 3bet to drive the BTN away to get position.
Luckily BTN did end up folding..

Flop: QT9 monotone, this is a super scary board. I am proceeding with caution. We do have pair + straight draw - I do like the bet but I am proceeding with caution.

Turn: I am betting here to buy a cheap showdown honestly. I would bet 45 and fold to a raise.

And I am checking back alot of rivers.

i mean this has almost nothing in common with the posted hand

id start by looking at 20bb sim ep vs btn call so at least the spr is close and the pre ranges are reasonably similar
