Standard spot against fish, call? - 50NL

Only about 20 hands at the table but villain is an obvious fish with vpip around 80%.

Turn call ok? Now what do I do on the river?

I would fold the turn. This is a super strong line by him and you probably only have 2 outs.

I'd call down cuz I'm a station I guess. He's gonna have a 6 a decent amount of the time though. Maybe 50-60%?

I don't think calling turns bad because you likely have 6 outs even if 4 are somewhat tainted and I see fish make this kinda play with sd value so they don't have to face a river bet. River I'd def fold.
