Line check.......

[Slap My Jack]

I'd like more information about how he plays postflop.

Otherwise it's go with your gut and __call/fold__ or wait for a better spot. And since we know he's bad, we can probably wait.

As for the line you took, I think you can check behind the turn. When you call the flop and bet the turn, you're saying you have a jack, it's also possible you have a flush draw given how weak you bet the turn. I think with your kicker I don't hate checking behind on the turn and calling a bet or betting the river.
