Also, the greens are not flat once you are on them. #3, #5, #6, #7, #8, #9, #11, #12, #14, #15, and #18 have very important slope(s) on the greens that dictate strategy and can make green reading very difficult. I could have mentioned other holes like #1 but only state the obvious ones. I bet I can read the greens better than most of the guys playing in the U.S. Open there because the greens aresubtle and tricky.
Also, while Chris likes the tee shot to right on #1, I think the ideal tee shot is as to close to the left fairway (formerly rough) bunker. First, this leaves a shorter shot in - perhaps wedge or sandwedge instead of 8 or 9 iron. Second, the green is very subtely sloped from right to left. Therefore, an approach from the left is hitting into the hill. This is important when the greens are very firm, which hasn't been the case very much in recent years. Third, the left greenside bunker isn't much of a concern to me when approaching the fairway from the left because I find that up and down easier than when you miss the green anywhere to the right.
If anyone cares to know the idiosyncracies/subtleties of every hole I can easily do it. Many of them I didn't learn until after playing the course for years.
