Ian:
In my article, at least, I was talking about the golfer choosing to hit a shorter drive (or second shot) in order to get a better stance for the next one.
The first I ever heard of this was in an article about the 1951 US Open, where a fellow competitor noticed that Hogan was always playing from flat stances instead of sideslopes on holes like #10.
Crystal Downs has at least two holes of this description. At the par-4 seventh, you pretty much have to lay up now that the bank down to the lower fairway is thick rough. However, on the second shot to the par-5 eighth, it's much better to play short and right than to be sucked down into the bowl below the green.
I don't know if Alister MacKenzie thought about these plays, or not ... I suspect not on the eighth, it's the kind of thing you learn only after playing 50 rounds of golf there.
I have tried to build this strategy into a handful of holes I've done, with mixed success. My first attempt was the fifth at High Pointe, where the fairway peaked at a ridge 235 yards from the tee, and then fell away into undulations much like the seventh at Crystal Downs. (Originally, you could also get behind a small cherry tree if you drove it too far.)
In its infinite wisdom, the management of High Pointe has now built a back tee on the fifth so you have to hit a full driver to get to the crest of the fairway!
