I don't think enough anymore

I just want to make sure I have this right. If this was an uncoordinated board, you would just call down. However, the prescence of a flush draw gives a strong possiblity of semibluffing so i.e. you get the most money in the pot when he still may be on a draw by raising the turn and if he does have a K you probably get a free showdown. If you just call down you miss an extra BB on the river if he does have a busted flush draw. You are getting more money out of him when he may still be drawing. Is this right? What do you do if you are 3-bet on the turn?
