Thats true in the vast majority of the situations, but on this board it's kind of hard to be bluffing other hands than the type of combo he picked, most hands have decent showdown value so he has to be bluffing some of his missed fd's and some hands like 7x or perhaps a 56ss, so I think his bluff is totally fine here.

solvers suggest to mix it up with AKxx combo's about 50/50, and AK with a diamond makes betting the high frequency play, so yea Im not supposed to be cbetting this combo 100% of the time. And villain is defenitely supposed to fold 44 to a flop bet for this sizing.

at 42'15 table 2 : i don't find that there is any value hands that benefits to c/r turn as you have plenty of hands which have a good equity and that who will always check back the turn (your one pair hand with a gutshot, pair+FD). Maybe hands like T8s, 88/TT which are blocking some of your T9/98 hands are better to check than the other good hands but don't think that it's great play to check those hands so i won't do it in bluff too. What do you think about his play on the turn ? Can u vbet two streets with J9 if we never c/r here, i certainly check call some Jx and QQ, KK, AA some fraction of the time

It makes sense to have some sort of checkrange range, and I agree that t8/88/TT have a lot of merit to go for a c/rAI, and he can balance it out with some 9x hands but perhaps he chose a QKo type of hand that has a far more equity vs a call than a hand like A9/K9.
I dont think ip should bet turn and river with J9, OOP will defenitely have a decent percentage of stronger hands.

just checked the hand in PIO, and indeed OOP should be checking 88/TT going for a c/r and IP should be checking behind turn quite a bit with KJo but defenitely go for a bet/c.
Even though pio wants to barrel QKo as OOP, I still think his play is fine.

is this rlly Brian Townsend?

I still change my play quite a lot in this spot, I worked on this topic with someone to figure out what my ranges should look like. Obviously not going to give my exact ranges but the way it was calculated was: think about these factors, how many % of the hands go 3way, equity HU, equirty 3way, estimation of R HU pots, estimation of R 3way, squeeze %...
And indeed ante games change your ranges dramatically. We do have to slowplay some of our top 5% hands to defend against squeezes, or we can very easily be exploited by both the bb and the button. There are a ton of hands where the ev is calling or 3betting is fairly equal so I like mixing it up with those hands (K8s/QKo for example)

I agree with your numbers here, it's very similar to my ranges against a button minraise (or 2.1-2.3) I am a little bit tighter nowadays than I used to be, because I had to cut some of my bottom of my cold call ranges because the results were quite bad with hands like QTo.

Please let me know if you have any other specific questions :)
Oh and yea please let us know if you are the real Brian Townsend ^^
