This is a very gross spot, based on stacks. Given stacks I think villain will for sure be calling all of his JTs hands pre, but probably not JTo. I think it's safe to assume that most of the time he might find a flop raise with JTdd. So he reps JTc/s/h, 3 combos on the turn. If he has offsuit JT hands then he obv reps way more combos.

There are tons of combo draws as well. This spot just really sucks because villain knows with a high confidence that you do not have JTs (I'm assuming you're prob not 3b this often), so he can continue to put a ton of heat on you on the river.

In practice I think I call turn and re-eval river and hope for a brick spade or club to call on, or a 9/8.
