low pp HU in pos vs semi loose TAGG

[bspahn]

player is 26/22 (classify as loose tagg or tight lagg?)
in any case, since he's often CR very light on this flop, I check behind, now what
do I make of his turn bet? If i want to get better at this game, I have to start making some better +EV decisions and I'm wondering what line you would take here, call and bet river if he checks - or check behind on river due to showdown value?

Another line could be to raise him up here as I have showdown value against a draw which he might call with, also I could easily have AQ/KQ etc here.

I wouldn't check the flop, even if he's raising light this is a good hand to bet/fold.

and this is because he should respect that from a super nit utg raise I should have an overpair here, and if he bluffs me good for him?

Let's say I bet near pot and he calls, are we turning this into a double barrel bluff on the Q turn - what's your line then?
