He can have 4 combo T9s 3 combo 88, 1 combo 77, 3 combo 66 for sure if he raise all of them, (and maybe some like 1 kombo K8s, 1 K6s, 1 87s very very rarely) so 11 value combination even if he play all the JTs bacdoors this way what is unlikely itself it's not enough bluff to U can continue. U also have T9s, KK, 77, 66 maybe even 88 sometimes, but that an exploitive asumption that he doesn't bluff, and U had also all the AA, AK, KQ maybe and don't want to fold maybe that much. So you can call once and decide on the river in position or U can start chb more on the turn with AK, KQ, and then U will have an easier fold with that hand maybe.

its close

in general I'd lean towards calling and calling smaller bets otr, folding vs bigger bets, but I certainly dont think that folding is in any way bad

I'd call, you beat some hands from his possible value range and you have 4 outs to a fullhouse, and when you hit a fullhouse, you probably end up stacking his straights.

further reads on the villain to help analyze the situation more properly? Vpip? c/r stats? call from BB stats?

in game I would feel beat here more often than not

I don't like folding the turn here to his C/R

I'm going to make some assumptions of his range here: Value hands being 66-88 + T9s he would C/R for value which beat us. I also think he can flat things , 87,s 76s in his BB that would check raise this turn for value.

You still have AA, AK and KQ-K9 in your range which you could realistically fire on the turn which he now thinks he get some value out of - he doesn't want to check to you so you can check back rivers so it would be a sensible assumption he would try to get value from this part of your range.

Also he might be tuning things like 55, 65s and 98s into semibluffs against the non 2 pair Kxs' and the AA you still have your range - these hands still have decent equity when called but from his view could be too weak just to call a turn bet and check/fold rivers.

Against the range I feel he could check raise with; 55-88, T9s, 98s, 76s, 65s you have 50% equity. I think it is well worth a call on the turn and see what happens on the river.

Yeah it's pretty close.
Given it's a rainbow board, he's going to have a lot fewer bluffs.
Players at this level are so weighted towards value when they raise the turn.
I think Samu's point about still having outs to a FH that will probably stack villain is important, and probably the deciding factor in making this a call.

I'd call and evaluate river, we block some of his value range....
