Over Check raise on the river?

pre-flop is marginal, but whatever. All sorts of hands can be in your range here occasionally, just make sure it's dominated by 99+/AQ+

Flop is fine but ffs bet the turn. Even 40c leaves villain less than pot behind on the river. You really want to be maximising your chances of playing for stacks in this spot
