i would not cb this texture, and i would not x/r either.
i think x/c flop, x/c blank turn (assuming turn will be HU), x/evaluate river

action after flop was: i called and CU called

Turn: Kc i check, Cu check, D bet 1.70, i fold

I like betting the board, because you can get called by worse, and you can play poker if you get raised. The other thing is most turns are bad for your hand, so ideally you want to take it down on the flop.

There are a lot of raises that will be drawing hands & semi bluffs, and you block out a lot of sets. You're only really crushed against made straights kq, 78 and j7 suited and even then you have some equity (16%).

I would make a meaty bet on the flop around 75-85%

Hands like AJ KJ QJ, hands with a flush draw and loads of pair and straight draw type hands will all probably call, 9 10 can also call. These are all behind your hand at the moment, so we can look to get value from them

By 'play poker' I mean reevaluate if you get raised, I'd probably fold to a raise.

At this limit standard it's to bet ,if you got any fish in pot bet big to extract value ,most of the time when you got raised you are beat unless it's an aggro/maniac player ,i would go for bet and fold if you facing a big raise .
