I respectfully disagree with the assessment of Pinehurst #2.
1) The fairways are lined with bunkers AND waste areas, which are not the same. Sometimes the waste area is firm with tiny grass strands poking through. Sometimes it is a hard pan which can help a lesser player get additional roll towards the green once their ball first hits the ground in front of the fairway. (And pros, too. I saw John Senden in a practice round at the US Open on the no. 2 hole. He shoved his drive far right and just dropped in the hard pan off the fairway. His next shot was a low long-iron that ran about 15 feet of the ground for about 185 yards and rolled the last 20 up onto the putting surface.) And sometimes they are actual bunkers with soft sand. Having a wide variety of sandy scrub, hard pan, and soft sand bunkers makes a miss off the fairway a different play every time. Most amateurs are decent at playing out of 1 or 2, but not all 3 types.
2) I agree that internal contouring cannot be used to work the ball, but the internal sloping of the green or the overall slope of the terrain does allow for one to hit at a fat part of the green and have the ball release to the hole. This can be from the fairway or around the greens.
3) From in front of the green the best shots probably are low running shots along the ground. During a recent round there we had a short-hitter that would have had to hit long irons/hybrids/woods into greens but instead would essentially lay-up on many of the par 4s so that he could chip/pitch the length of the green. When he tried to fly the ball to the hole it rarely held. When he hit to the front of the green and played a release he was able to have a long chance at par.
However, from any other side of the green a ground shot was almost impossible through the dormant bermuda (although we did see a local member use putter to get to 3-feet from the 8th tee to the 7th green after his approach went long). Unless you were over the back of a steep green (#3, #8) and the pin was in the back the best shots were from those that took a sand-wedge and worked a lofted pitch around a green slope try to get close to the pin. I know a lot of the pros were putting from off the green with putters and hybrids all week but I did not see many amateurs that had the touch required to pull off such shots.
