Missing a shot you know how to hit or missing that 'every once in a while' shot? Or is it the same no matter what shot you hit.
Missing a shot I know how to hit, mostly because I make a point in my game not to hit "once in awhile" shots on the course. A sideways pitch back into the fairway and 50 yards closer to the hole is (or should always be) the play if the alternative is some kind of "low, hooky 6 iron."
