My favorite, mentioned here before, was playing the New on a Sunday with a strong breeze at our backs going out. After our round, we dumped our clubs and walked TOC in anticipation of our scheduled round the next morning. We got to a bench up on a dune overlooking the 14th. We must have set there for 10 minutes trying to imagine how to play the hole into the strong headwind that day. We couldn’t; it looked unplayable. We awoke the next morning to rain and the same 30+ mph breeze, but the wind had shifted 180 degrees, making the 14th play directly downwind. It was an easy driver and 4-iron on to the green in two. From unplayable (for us) to benign revealed the beauty of TOC in a very profound fashion.
BTW, some months later I read in a book, I think Mackenzie’s Spirit of St. Andrews, how to play that hole into a strong headwind: play down the 5th fairway and approach form there. Another good lesson in the brilliance of TOC that I wasn’t smart enough to figure out at the time.
