I don't know if I'd agree that #1 at Yale is one of the 2-3 best holes there but nevertheless, it is an excellent introduction to the whole aesthetic of the golf course, which is tremendously important at a golf course with such a hugely strong aesthetic as Yale's.
If you want a CB Macdonald/Seth Raynor course where the opener is one of the best couple holes, almost without any possible argument, it's Old White. I don't know of many better opening holes than it.
In a few of Ran's profiles of courses on this site, in the case of courses that begin with especially long par fours or par fives, he seems to emphasize the way in which such holes are good because they bring the player away from the clubhouse quickly. I would agree, citing Pine Needles, Sunningdale Old, Newport Country Club, Shelter Harbor, and Hartford Golf Club among the cream of golf courses I've played.
