It does depend. Sometimes you'll have to forget firing a second barrel on the turn even though you know it screams "I have AK and I give up"
Sometimes of course, it is so right to do it you'll get him to fold 2nd or 3rd pair and cheer. It depends on what read you have on the villain. What do you think he has, and how likely do you think he is to lay it down if he's ahead of you?
