Boy this is really close. I mean, he has to put you on a pocket pair of some degree after the flop/turn action, and the river changes nothing so it doesn't seem like a great spot for him to bluff since you look like you're in calldown mode. However, I think you're right that he's mostly ruling JJ+ out of your range and might just feel you can't take the heat.

Any read on his willingness to 3barrel, or bet sizing, or whatever would obviously be super useful. The fact that he's already running you over makes me more inclined to make a stand here for various reasons. I feel like I would call this but hate it.
