Was unsure of what to do on turn. Thought Villain had a lot of Tx that calls, also thought a turn check would look too transparent so I sorta bet for balance/protection, but looking at it in retrospect I now think he has way too much Ax for me to bet here and I'm just burning chips trying to balance/protect. Then on river I thought he was betting only busted flush draws and Ax so had to call. I'm thinking best line is check call turn check call river. Unsure of if that changes if he's slow playing sets even a small amount of the time. Thoughts?

The hand changes a lot depending on whether villain is a fish.

In theory you're supposed to check a lot vs IP callers with tight ranges. Checking everything if you don't have more sets/2p than villain is a good simplification.

Yeah not a great turn for you which means you should be doing a good amount of checking. If you think villain will play very aggressively vs check you can just XC JJ-KK and check all your value. Personally I would XF unless they go small.

Weird river size by villain definitely take a note on that, seems close I might fold because of your large flop sizing.
