I'm not certain of Old Mac -- haven't played it. From Ran's write-up, and comments from others who have played it, it does seem like the kind of course very much conducive to match play, in part because it seems the width there, plus other features of the course, create varied ways to play. One line about Old Mac in Ran's review that has stuck with me is his view that Old Mac, of the four Bandon courses, might be viewed as the easiest by the high-handicapper and hardest by the low handicapper. That seems like a course that has options galore on how to play it, and a clear sense of harder path/easier path which one would attack it.

I think there are great courses that are simply tough hole-in and hole-out -- Winged Foot comes to mind, and from what I've heard Butler in Chicago might be like this. Nothing wrong with those course -- both I think were designed to be tough, tough courses. I'm just not sure they'd be as appealing as a course with the potential for variance in scoring, and options about how to play it. Again, citing Ran again, and from past threads, it's interesting to note that Oakmont -- for all of its reputation as a very tough test -- has five par 4s that often play under 400 yards. But that's also coupled with some incredibly stout par 4s and par 3s that play 200+ yards, including one at 280 yds or so. I think Oakmont in the early Fall, fast and firm and its rough trimmed a bit from US Open specs, would make a nearly ideal Ryder Cup venue. Augusta the same thing, particularly given the potential for fireworks late in the round (holes 12 on in), where most match play matches are decided.
