Wouldn't life be better if we just defined "golf" (semantically at least and ideally according to the Rules as well) as fitting to what Ian's got in that Riviera post, and as for the rest goodbye to all that?
I vote Ganton for a Dixie, which in Doak's book doesn't even rate a 9 and which others keep cramming together with Woodhall Spa, demonstrating that Schelling wasn't just writing of Pearl Harbor but of human nature when he wrote of "a poverty of expectations."
A masterful routing over ground that is not spectacular but subtly decent, which sums up the course and highlights that in lesser hands it probably wouldn't have merited so much as a 5. Up and down slopes, across valleys, there's a lovely rhythm to the holes and a sense of an integrated whole that is vastly more than the sum of its unspectacular parts.
Angles, including the use of bunkering.
Integration of greens with fairways (quality of green complexes) -- does any course do seamlessness better? The pitch and cant of the greens...
Relating to rhythm of the holes, the mix of holes: stern par 4s, short par 4s, easy 3s and a brutal 3 -- in a match the possibilities for holes won and lost start in earnest on 12 and don't let up. Not a course of halves.
Detractors will note no spectacular / signature holes, how the par 5s play for the strongest players, and an 18th which is not quite up to the level of the prior 17.
Is this the best course extant that shares a border with a farm?
