Why do you think he has a flush draw as the bulk of his range?
of him having either a Queen or a better Jack are pretty big.
First of all, I suggest you fold J8o preflop, even in the button.
I'm pretty sure we're behind on the flop. We're getting reraised, you have 27 hands on villain, so I think it's best to assume he plays straightforward for now.
I'd put his range on a better jack/a queen or total air he's trying to bluff you with. I actually think we're way behind on this flop, so I'd fold.
We're still behind on the turn so as played I'd fold here as well.
