Niall notes:
"I'm coming to this discussion a bit late but would like to pass comment on a couple of points. Bob in his quote above refers to contours being less obvious than bunkers, well I'm not sure thats true. Perhaps its conditioning, conditioning of the mind that is, but I play most of my golf on links (although I play my fair share of parkland golf as well) and therefore the first thing I'm thinking of is the roll of the fairway, almost reading it like you would a putt. If thats what you're used to you don't need very big humps or contours on the fairway for them to stand out. Once you figure that out you figure out how to avoid the bunkers but its the roll of the fairway that you look for IMHO."
Niall -
Some people are better at reading contour than others (you sound like you are very good indeed), but it seems to me that analyzing contours is almost always a more "subtle" process than analyzing other sorts of architectural features.
That's because contours usually are, in fact, more subtle than other kinds of architectural features. Without a fairly deep familiarity with the course, reading contour will almost always be harder and less certain than reading the playing implications of a bunker or a water hazard or trees or o.b.
Which leads me to the notion that the "subtlety" of a course has less to do with some abstract approach to golf design. Rather it has to do with the kinds of features a designer elects to emphasize. Thus, relying on contour as a primary architectural feature (take OMac) is the reason the course is perceived as being so subtle. That is the same reason, I think, why TOC is also considered a subtle course. It too is about contours.
