With only a 5% pfr, his range of hands might be narrow enough that a flop fold is in order. [img]/images/graemlins/shocked.gif[/img]

With a bit of a wider range, I think you can entertain the check/call, check/call, bet line.

I agree with the others who say you can't fold the turn the way it played out.

edit: check fold an Ace or K turn or river.
