Yea i don't disagree with most of what you said, but that wasn't what i was saying. Ofc the flop peeling range is going to be wider for every player than the turn peeling range. But what you are doing, is putting alot of Tx hands into villain's range that he would float the flop with. Ok, fine. But that means that he floats the flop with a FAR FAR FAR wider range than those hands. If you think Tx is a decent portion of his range, then we can presume he is folding very little on this flop other than 8 or 9 high sort of hands. If we accept this, then it is likely that villain will be peeling turn quite wide as well. So gutshots, A high , bigger overcards (QJ, KJ etc), all flush draws, straight draws, etc. etc.
I do not think that it is an accurate assumption to say that villain peels flop super wide so that we can include alot of Tx hands in his range (this is ofc the only reason we should ever be thinking villain has Tx as part of his range) but then folds everything that misses. If you follow what i am saying, and we ignore draws for a minute (since draws are a standard peel on the flop) this would mean villain would have something like <30% fold to cbet on this flop but then fold like 90% to turn barrel since the only part of his range that can continue as made hands are overs that hit and pps. Sure there is the odd player like this but i'd argue that most ppl who peel flop extraordinarily wide also have an extraordinarily wide turn peeling range as well. ie. a super wide flop peeling range that is wide enough that we can put some random over that hit on the turn into his range increases the likelihood that villain will continue to call light on the turn, as it is a characteristic of villain that he calls light (unless you have a specific read that he peels flop super light and folds turn unimproved).
I'm not sure if i am making this clear, but maybe this will help. A tight flop peeling range will have very few Txs in it. AT and Tdxd are about it. Therefore, if we want to put Tx hands into villain's range on the turn, we MUST assign him a very very wide flop peeling range, as if he is peeling TQ, he is also peeling K9, K8, J9, QJ, and many many other overs + probably any sort of draw. So why should we be assuming that he is just going to automatically fold a HUGE portion of his range on the turn, when our first postulate is that he peels the flop very wide.
At no stage did i say i expect villain to peel a hand like J9 twice trying to hit, but if he peeled 9T on the flop, there is a good change he is peeling A high or whatever junk on the turn as well.
So then the only thing to consider is how villain's range has changed once he bet the river. I am taking it from the point of view that a bad villain is unlikely to be able to vbet light here w/ 88 or 99 once a T hit on the turn and we bet it. Reasons being taht i don't think that fish hand read well at all and they'll probably just check hoping that you don't have a T. They have to have your hand pegged pretty well to find a range against which they can value bet against and expect to get called by worse. And honestly, as i said before if a fish bets 88 here i wouldnt' be suprised to see them bet 55 as well, since some players just bet without knowing why. Maybe they wouldn't turn A high into a bluff, but it shoudl be clear to some1 who can read hands that a weak A high is never good here (tho i don't think they can read hands) and non-solid players just do some weird things. If villain did have A4 here they SHOULD absolutely bet it as it is almost never ever good.
So to sum up this incredibly long and probably poorly worded post - i think that villain's range is still fairly wide on the turn and i don't think that the river improves any of his hands. I think villain is repping a somewhat smaller vbetting range as i wouldnt' give credit to a bad player to bet 88 for value here. And i also think that this bet sizing can often be a bluff.
That said, if villain bet out 3/4 pot here i would snap fold as i would be less inclined to think it was a bluff and we are getting terrible odds. But i definitely think we are good more than 1/5 here.
Basically, i do not like assigning villain a very wide flop peeling range and then thinking he only continues with Tx/pair/draw type hands and then thinking he can vbet a pair lightly when hero has had the action the previous 2 streets and he will check behind his missed draw hands to the point that we aren't good even 17.5% of the time.
