SUP...
this is a hand I post to reclarify my framework with which I should/could assess these situations.

Unfortunately villain is completely unknown other than that he plays a full stack.

Recently in my game I came to the realisation that my next big "sticking" point probably should be how to PIO/approach 3b pots from the turn forward regarding ranges and betsizing since I feel I got everything else pretty close to a somewhat non-super-much-losing/PIOish/GTOish ...

In 3b pots however there is a lot of confusion left regarding lines etc. especially from the turn onward.

This hand is a typical example for me

FLOP: I feel we can bet 1/3 or 1/2 or we can check/call

TURN: I bet because he is unknown and therefore potentially fishy and calldown happy but again I feel we could c/c c/RAI bet this size or bet smaller....

RIVER: Is this bet too greedy? Is this a c/f? c/c? c/c this and shove AQ+? If we c/c this, do we c/c JJ?

In general these spots give me headaches with the TT/JJ/Flushdraw QJ/KQ parts of my range and my gut tells me all lines are kind of equivalent and never super profitable

Has anyone studied this in PIO? Has a good video/article to refer to?

Kind regards
