The is probably my favorite subject in golf outside of teaching and equipment.
Course design and set-up.
Here is one for you....
Let's take someone I will beat 90-95 times out of 100 but can play a little...my example is a young guy named Jared I know and have played with a decent amount.
If he plays two times a week for two months in the summer, and hits balls a few times, he will shoot 75 on a basic course if he plays good, but can go lower 9 holes at a time, and could be a really good player.
If we play Whistling Straits 10 times, he will be me twice probably, and 1 or 3 times maybe.
If we play Pacific Dunes he will pretty much never beat me. Maybe twice out of 100 rounds.
Here is another example:
If I play Pebble Beach 10 times from the resort tees, I will have a low round around par and a high round in the low 80's.
If I play English Turn 10 times from the blues, I will have a low round in the high 60's and a high round in the around 80.
If I play Pacific Grove Municipal 10 times, I will have a low round in the mid 60's and a high round in the mid 70's.
The last time I played Whistling Straits, I made 2 birdies, 2 bogeys, and 11 pars...
....three triples and a quad.
