Pat,
Sorry for the lag of response, I've been shoveling this blizzard for the last couple hours.
I really don't know the answer to that question...about why when you turn the purpose slightly, the experience of even a great course changes. But I know you're right because I have witnessed and participated in dozens of Golf events where that which you report is so very true
My first considerations though, are telling me its fundamental to the "enjoyment" of the game and how that enjoyment is served by GCA ideas. I think about those pre-Allain Robertson days (up to 1830?) and what the game was like when it was very basic, very primitive to what we do today.
I've got to figure that with wild lands and rabbit paths and sheep making escarpments and indefinite rough-hewn conditions, the game was almost entirely fortune. How could the quality of your swing, your stroke matter when any little imperfect hiccup could alter the result of play? This is to say nothing of the equipment, hickories and first iterations of the feathery - which changed from half hour to half hour. Technique was just about inconsequential then...so what were they doing? How ridiculous would it have been to say someone is the Champion Golfer, when their ball survived a little better than their opponents or hit fewer grains of grass on the way to the hole?
But to address the medal side of it, and those well-understood feelings of the difference between a match at Pine Valley or a medal score at Pine Valley...there is the "finality" of score which Nigel was referencing. To go further than his brief post, I say that in some ways the medal score is anti-Golf on a fundamental level. Not only can the entire day be summed up by a big number...make a 9 on one of the first three holes and your medal purposes are shot to hell...but the day, the Golf is, for its purpose, over. You're not winning and though grill room sympathies are an adjunct of the culture we love, in the end...no one else really cares that you fashioned a 4th place 81 with that horrid 9 on #3...you're the only one who can really get something out of it.
And what I mean by "anti-Golf" is that Golf's most fundamental feature in my eyes is that no matter how bad you f*** up a particular shot, there is an outside chance that you can redeem it and erase it with the next shot. You can make something "perfect" or beautiful from the ruins. It's at this juncture in the GCA discussion that I am so against penal architecture, out of bounds, forced carries over water, haystack rough...they all conspire to make you stop playing...to dampen that enduring sense that, "I can recover from this." such features, especially when they are larded in a particular course, just kill the very reason you might play.
No less an authority than Bobby Jones said, "The worst thing about golf is looking for Golf balls." My take on the wisdom of that is that Jones sensed that when you're looking for a golf ball, not only is the spirit perturbed, not only is time being wasted, not only do you have to be humiliated to go back to a tee or a previous spot, not only is the Golf (medal or match) consequence heightened, but...most fundamentally...you're not playing Golf anymore and neither is the party(ies) who are helping with the search. No one is playing Golf.
I don't know if this advances the discussion in the way(s) you might have hoped it to be framed, but there is "something" there...i n that idea of, fundamentally, what pleases us about Golf and a chance to make a better reality out of imperfection...and how medal has a finality to it, a historical report, that seems to suspend it in time. A match ends too, but in another poignant sense, the wise and happy golfers know another match is still to come, one where fortune may be on their side.
Medal and playing against a whole field of golfers (for 99% of us - and that's who we care about, I hope) has a pre-determined result. I am better than my friend Joe and neither of us are as good as Tiger Woods; there is always someone who can lick you. In match play and the measures of fortune AND the courses that receive this and mollify this (match play courses) a different spirit and sense emerge from the enterprise.
If you take what I reported about TEP's thought that Golf is only ball and stick game where the ball itself is not competitively vied for, and look at what medal play does (competitively determine the most skilled) it can be seen that there is somethign about THAT measure (the most skilled) and the courses that reward the most skilled (medal courses, if I'm right at all) that is anti-Golf, that Golf is more about allowing its players to do something else, recreate, make a new reality of what it empirically not true. To solve a problem. Whether you or I get strokes or not, we've got a better chance (infinitesimal, but apparent) to match Tiger at NGLA than we do at Firestone or Bay Hill.
And there's something very great about that. And to serve that essence is what one characteristic that makes for great GCA.
cheers
