Chappers,
The drives at 9, 10, 13, 15 will trick them. The line isn't obvious on any of them until after a few plays and even with a caddie, they won't completely believe where to hit it.
The approaches to 3, 6, 12, 15 and 17 take time to learn, also.
But then again, the golfers we're talking about are far better than you and I...
