it is important to rate which part is the worst so you can work on it, just as well it is important to play your strenths to your advantages too. play the course smart, as in the example above. he should work on his sand game but untill he does, since his chipping is pretty good it there is a bunker on the left side of the green, play to err to the right side of the green, if you hit it great, if not your chipping is good so it isn't too big a deal. so work on weakness is important, but don't forget to play your strenths too.
