Tom, I was thinking of a hole, green, bunker, contour or any other feature that the architect felt was rather pedestrian that somewhat surprisingly turned out to have significant strategic merit or be great fun. Perhaps something the cognoscenti unexpectedly raved about.
Make sense?
Usually I have a pretty good sense of what golfers are going to like; I think that's why my courses do as well as they do in rankings. But, sometimes I build a feature I know a lot of people aren't going to like, just because I think it's the right thing to do.
Often, though, what I see right away as the most natural hole on the golf course does NOT turn out to be everyone's favorite. In hindsight, I sometimes wonder if it was wrong to work harder on other holes, and let the natural one rest on its own merits, instead of trying to enhance it . . . but I have always felt it was better to err on the side of doing too little instead of too much, just to be different than everyone else.
For example, when I routed the back nine at High Pointe, #10 and #11 and #12 and #14 were the holes that jumped out at me; #13 had a cool green site, but I thought of it as more of a connector hole. And it turned out to be most people's favorite hole on the course, including my own.
The sixth at Pacific Dunes was one of the first holes I found on the map; but it was eliminated from the routing early on, partly because Mr. Keiser thought it was too short, and only snuck back in at the last minute. I actually had to hit a bunker shot out of the deep greenside bunker to convince Mr. Keiser it was playable, and thank goodness, I pulled it off on the first attempt -- I generally try and avoid that bunker when I play, but I don't think I have gotten a ball on the green from there since my demonstration!
As for a feature that's surprised me, I would say that I didn't realize when we were building Barnbougle just how many of the greens would allow you to play a shot off a bank at the back or sides of the green, to get close to the hole. The last time I played there was with a couple from Singapore who I met at random, and once I showed them that feature on the 4th green, they were doing it the rest of the day!
