Playing from 2 sets of tees

If two golfers are competing from different tees you cannot simply compare course handicaps.

You must make an additional adjustment. An extra adjustment is made because course handicaps only take into account the difference in slopes - but when you play from a different set of tees, you must take into account the difference in course ratings as well.

This extra adjustment is made by taking the difference in course ratings (rounded to the nearest integer) and adding that to the course handicap of the player playing from the harder tees.

For example, player A has a course handicap of 10 from the white tees and 12 from the blues, and player B has a course handicap of 15 from the white tees and 18 from the blues. If they both played the whites player B would receive 5 shots (15-10), and from the blues, 6 shots (18-12). But, if A played from the blues and B played from the whites, B would not receive 3 shots (15-12). You would take the the difference in course ratings (71.2 for blue - 69.1 for white = 2.1, rounded to 2) and add that to the course handicap of the golfer playing the harder tees (the blue tees) - player A's course handicap becomes 12+2=14. Now the difference in course handicaps is taken to get the total number of strokes given. Player A would give Player B 15-14=1 stroke only.
