Great topic!
I just played Pinehurst #2 for the first time a month ago and would say to design the greens in a similar fashion. I've never been so nervous to hit an 8 iron to a green (I'm a 3 handicap). The greens reminded me of a diamond with multiple little areas that cannot be seen with the naked eye, but learned through repeated play. Best surrounds. Best chipping areas. Highest penalty for missing. The most my brain has ever locked up over a short chip to a barely missed green.
As I have said and believed in the past...if being on the 'correct' side of the fairway, per the days pin doesn't matter than the design is weak. Again, at Pinehurst, being on the correct side is CRITICAL to score. The most I've ever encountered. Even at my home course (Holston Hills), both Ross-designed, being on the correct side is helpful but not CRITICAL on some holes. In other words, you still have a decent chance at par. At Pinehurst, this is just not the case.
Incidentally, I just played in the club championship at Lookout Mountain. It's a Raynor with completely different topography and much more severe sloped greens. The course is 600 yards shorter and 5 shots harder than Holston, easily. Some pins simply can't be accessed without a high degree of skill, luck, and years of play. The winning score for two days was -2 with the toughest pins I could have ever imagined and very slick greens. Camargo (Raynor) hosts the US Am qualifier every year. The course is maybe 6600 yards and routinely -2 to -3 qualifies. You can hit every fairway at Camargo and Lookout and still score like crap, the greens are that tough to learn. You rarely fire at pins, rather over time, you learn the angles.
