Why aren't we raising turn? Great barrel card for V and he can be barreling lots of wrap + FD etc and we block most likely sets. I would also expect value hand to be betting bigger on River given board texture

I'm calling river for one simple reason:
You're at the absolute top of your range.

- ~No TT-77 comes to river as played.

- I would expect regulars to raise almost all their AT hands (which calls from the SB), because of the drawy texture, and the fact that many AT hands will have alot of backup since you called from the SB. It's not like you are calling AT52 here (I'd suppose).  So if I'm villain, and I'm thinking about your ranges, I'd come to the conclussion that you're not super strong.

-Villain is making it extremely profitabel for him to bluff, given betsizing, and if you end up folding as strong a hand as T2P in this spot, when KQJx misses, turned flushdraws misses, you are setting yourself up for major super duper exploitation in just about any game above $10PLO.

It's not like I'm super happy about it, since I do feel many players will check back instead of going for light value with hands like A7, A6 in this spot, even though that might/might not be warrented. But still getting 16:28 folding just seem like range-spew on your part.

With regars to turn being a standard raise; There are regulars (whom I feel barrel to in-frequent) where I'd rather call and play river, rather than raise and GII 145bb deep with ~no redraws.

IMO I would definitely raise ott. I mean every river card complete some straight and it seems from his cbetting stats that he is betting very wide range. As played I am calling vs this guy.

A problem with raising the turn is, we can't have much air in our range and are actually repping a very strong (yet narrow) range.  We probably don't have many 33/77 in our SB calling range, and TT probably raises on the flop.. that said we are repping pretty much AA and AT or some monster draws (again, few combos).  When our turn c/r range looks that strong, I don't think villain can make a huge mistake and get it in bad for 150bb or something, and if he calls, most rivers suck for us (which is true when we just c/c on turn, but we have a way underrepped hand and the pot is much smaller, he can still triple barrel with air)

I guess there's still some merits for turn c/r, mostly for protection, but I don't think this is a slam dunk c/r at all.  Especially when we have 0 redraws.

In general, arguments like "he can't call with worse" are always easy to counter with; "well just raise air then, and let him fold his way to hell". (I don't actually mean that, but if you find yourself never ever getting value with turn check/raises, your game would probably benefit from some bluffing).

If hero is worried about balance / not getting value, which I don't think he is, but which I think he should be, he should check/raise/fold hands like KK, QQ, and check/raise/call (as a semibluff) hands like good flushdraws(straightdraws) + picked up ace-pair on the turn. This could eg. be AK98, or A998ss. 

Now this might be total spew, all depending on the situation, games and villains he is playing. But what I do feel pretty strongly is that if hero is folding this hand, as played, he is making some pretty terrible range-lines, and should stop what he is doing, and think over what hands he is calling river with here (as played) if he is folding this hand. 

Then he should proceed to think about what hands he is calling turn with (as played). 

Then look at the odds villain is giving himself with his betsizing, and what percentage of hands hero needs to call (or raise) on the river, to not be exploitable. Then hero would realize that he is utterly fucked (as played).

I remember back in the day, when I got coaching from a far better player than me. I kept slowplaying unsafe nuthands (eg 67 no redraw on 589tt), and I always used the argument: "but they never call me when I raise". and he just kept hammering: "well just raise 66, 77 and random 6's or 7's then till they start calling you".

No, you absolutely do not need to construct your game as to be un-exploitable. You ~can't be exploiting others, while at the same time playing un-exploitable. And exploitative play is where the money will come from in poker. This is like the ~definition of exploitative play (or close to it). You are making several points which I think should be adressed, so I'll just try and work my way through them, not necessarily in any particular order.

Your job at the poker table, is figuring out which exploitative line which will yield the most EV. 
Can also be written as:
How can you distribute different hands, into different ranges over the different streets, as to make as much money as possible.

Now, this might seem like stating the obvious, but the obvious needs to be stated every now and then. Also; as a low stakes player myself, I often find myself realizing I (probably) went for the lesser +EV line, because that line was "easier" to play. Now let me give you an (extreme) example, and you'll probably understand:

Villain plays 30/20 over a large sample.
Cbets flop 100%.
Cbets turn 100%.
Note:
-Folds alot to raises

So I call with some hand **** in posistion, and raise a flop where his range is weak, like maybe 654r after he is raising from UTG, where he is tight. This is surely a +EV bluffraise. But would it not be more +EV to call flop, and raise turn instead? Or even maybe river? It's psychologicaly harder to do, since you loose more when he has some hand that actually connected, like AA87, but if our reads are good, that will yield more money in the long run.

"But, what I what to point out here - do we always have to follow unexploitable range lines here? (especially vs bad\more like loose-passive player)"

No, but knowing how to divide your ranges in an somewhat unexploitable manner will always help you to better exploit.

And last; be careful to classify other regulars as bad, unless you have some pretty rocksolid reaons. We all make mistakes, or we would be playing alot higher. Its easy to see and say things like: "this regular is cbetting so little on my stats". But then consider he might be playing in games where alot of cbetting is not warrented, because of multiway pots, and/or many fishes at the tables.
