Probably c/f turn. We're against a nit and his range for calling the flop and firing the turn crushes us.

I can't see us getting any more value out of worse hands on this turn and we wont fold out any aces or better.

Also if he has a hand with SD value such as a weaker king he is likely to check behind and we could consider a small value bet on the river. c/f is good on the turn because we don't get bluffed often at all here and are clearly crushed by his range for betting the turn. Also we can keep weaker SD value hands in to the river where we have more chance of extracting value.
