Think it was Hogan that said he only hit 10 shots per round exactly where he wanted it and how he wanted. The others were an exercise in getting it round. The biggest course management fault and one I know I am guilty of (but trying to improve) is under clubbing and thinking just because I'm 150 yards (normally a smooth 6) that is the right club. If I clubbed up more often and hit a smoother 5 I would get to the centre of the green more often and not come up so short (where most of the trouble is)
