One of the coolest examples of subtleties, for me, was #5 at Tumble Creek.
From the fairway there looked to be a huge ridge that could help spin balls back to a front pin. It turned out it did not, and what looked to be a huge contour was really a {somewhat] mild slope.
Once on the green, I was once again fooled.
Thanks to Mr. Doak's advice, I hit the putt a bit harder then I might have otherwise, yet I was still short. I was like, wow.
I felt that was a good way to chllenge the player, as it made me think and it forced good shots or otherwise there would be three putts.
Though most of Tumble's greens had huge, sweeping contours, this change in pace was really cool and kind of messed with my head.
It was a good way to challenge the player, and adding diversity at the same time.
will add more later..
