How would you play this? I think this is pretty standard, with villain polarised on the river. What else do you think we should check call turn and river with against this guy, or with balance?

Villain was something like 30/20 over 30 hands at this point. My provisional note was: suspect sticky post flop, possibly fancy play syndrome.
