I agree with raising but I'd probly raise a small amount maby 5$ this should be enough to turn him off a bluff, and he will probly re-raise all in if he has the flush. If he does re-raise all in now you have to think he has the flush. I would give him 80% for the flush if he does go all in. If he has the flush you have 10 outs so thats about 22%. So if he does re-raise all in you'll win if you call about .2(.95) + .8(.2) = 34%..... so I forget what your pot odds are here but its up to them. If your stack is such that you wont be able to get away from the hand if you do raise his turn bet then just go all in.
