x/f. I don't care about balance, I just try to play good :)

Intuitiveley I would bet it w flush blocker. But when I tried to put our range, I realized, that we should ch our entire range river, cause from 55 river comb u have 5 flushes and 3 sets, and I dont think, that we have to vb w QQ (AA, JJ I would ch flop). So we can bluff less flop and ch/c w KQ wo backdoor fd. If we ch/c KQo flop, we have 43 comb river, can vb 14 KK+  and bluff KQs A5s A3s.  And ch/c some AJ QQ w blockers. Or ch/push some A blockers and some nuts flushes(but its again closer to ch our entire range)

you say that there will be 3 x 89s combos in your range

Can i ask why they'd be in your barreling range?

(OOP ranges is something im working on currently).

If he's one of the bigger winners on 2/4, and he flats your open from the CO I think we should be able to narrow his cold calling range a bit more precise, do you have any information on that? Many people 3bet AJ for example in these positions pre-flop.

Also I am struggling to find folding combinations in his range, I am sure they are there, but what calls twice on this run out and folds the River, that has to be Jx which he probably has so little if you ask me (probably only a few Jx suited combinations that flat preflop). I think if he is decent his range is very strong with a large part of it being sets/2pairs/flushes that are obviously not folding, I also think you underestimate the backdoorflushes he could have, I don't see a reason why he can't call the flop with more backdoorflush draws than just the ones that had gutshots on the flop.

I wouldn't advice bluffing here, and I wouldn't worry about having optimal bluffing frequencies untill we know that he can have more fold combinations on the River.

Your Kc blocker is extremely relevant, as it blocks a significant portion of Villians BDFD range.
Combine that with the fact that he never has a straight here, you're at the bottom of your range, Villian only has JTs for two pair (probably raises turn), this is a clear bet.

It's probably mandatory, too. If you're betting your flushes, and JT+, you need this hand in your bluffing range.

I rather have a wide cbetting range on this flop I want to bluff it alot

I think its not always good  vs strong opp, cause its so easy for him to defend enough on 24J. And you have lots of reverse implied with KQ, cause he have all AQ AK,QQ slow sets to river and so on. 

But if you get to this river, I agree with Chael, its a good hand to bluff.

Its hard to say what cbet freq is optimal on this flop, some good players cbet about 40%, some about 70 and balance their range by ch/c some turns rivers

This is a pretty interesting spot I think come up a lot. I semi modeled it for fun, I'm playing live poker atm and have too much time :) 

If you bet river for a pot sized bet you can optimally bluff 50%, so lets assume you get to the river this way w the following (now) value hands that are strong enough to bet river; AcKc, AcQc,Ac4c, QcKc, Ac5c, 8c9c = 6 flushes, TT = 3 sets, AA (6), KK (6) = 12 overpairs

I just assumed here that you'll be checking your Jx and QQ OTR, + the 3 combos of JJ and 3 combos of JTs to have some strong hands check as well. 

That gives 21 combos to value bet here. For a pot sized bet you can add another 21 bluffs. If we assume you're barreling most gutters/broadway cards OTT (which might be too much btw, I dunno, but there's a lot of combos of them) I would def choose the first to be the ones w the Ac, Kc and Qc in them. That would be AcJx = 3 combos, AcQx = 3 combos, AcKx = 3 combos KcQx = 3 combos, QcAx = 3 combos, KcAx = 3 combos, QcKx = 3 combos, tot 21 combos. 

So basically using your Brodway cards in this spot that has a club in them should make pretty good bluffs. Your opponents range is still uncapped on this river (though I think u have a slight advantage, he'll still raise a few value combos/semi bluffs ott) so choosing the right blocker hands to bluff should make a big difference. 

If you bet bigger you can add more bluffs, but I'm thinking it's not a great spot to overbet, like said villain can still have flushes in his range and if you overbet you probably don't want to bet your AA and KK anymore so u won't effectively be able to add more bluffs anyway... But pot seems fine to me. If you bet smaller you should probably remove a few of the bluffs though. 

How you play your hands also makes a difference for how many hands you get to the river w this way, will you ever c/c a draw on the turn, do you often c/r strong hands on earlier streets etc, but still think the club blockers are good randomizers to bluff with. I think you can give up the rest of your air here. And maybe review the turn to see if you are betting too much there.

What wgould he go with a2cc on flop then and a4cc as you didn't put those in his range...

what do you guys think about 1 bet sizing OTR for ~1/2pot?  It feels like theres still some value left with KK-AA, and villain doesn't really have a significant subsection of his range that can exploit us for c/f'ing 100% after we check..

I'd be surprised if we're not supposed to have 2 or even 3 sizings OTR , but for the sake of practicality i would like the idea of 1 betting option OTR in a spot where it seems to work well if he's still supposed to raise sets+ vs our merged 1/2 bet (our range is still weak enuff that our flushes still get really good value facing raises from the types of hands that would have called a larger bet)

I like check-calling turn by the way. Gives us a good opportunity to steal the pot OTR if it goes check-check, allows us to realize our equity, makes us tougher to play in general (IMO). I know it's counter-intuitive to play passively when we turn a semi-bluff hand but this spot looks good 4 it.
