Flopped straight flush how do I get max value?

I think you have to raise the turn. I agree with Cornell - if he has Ac or Kc, you have to make sure you get paid. If he has a set, he is also going to stay in because he may not put you on the flush, or thinks he has a re-draw. On the river, you might only get paid off by a made flush.
