Course management (imho) starts during your warm up just prior to your round. Very few golfers can hit the same accurate distances day after day. Even the top 10 golfers in the world are not 100% round after round. (maybe 99%) During your warm up you will find, for what ever reason, that you are hitting longer, or shorter, that day. Those are the yardages you will be playing with on that day. Some days I am little more left, or right than normal, so I make adjustments to play with what I got that day.

Also, in addition to knowing your yardages with each club, make knowing the "carry" yardage of each club a priority. You may hit a 5i 180, but the carry might only be 160. If there is trouble between the 160-180 yardages, you could roll into it. GJS
