2nl - Should I be looking for extra value out of 2nd pair or checking

[sean457j]

Villain is around 80/60 and is sometimes just going crazy post flop. I wouldn't normally play this hand to a raise OOP, but villain is too aggro with air to pass this up. Should I always be betting on the river here, or is it fine to check?
