Never crossed my mind either way on any project. Just not a criteria I consider. The 16th at Sedgefield has a horseshoe green that provides the best collection area for an ace I have ever seen. I never felt it should be used for a hole location and was more of an internal swale hazard on the green. Any ball entering the bowl will skirt the one small placement area.
I need to play there more often when they stick the hole there having never scored an ace!!!
Kris Spence,
Thanks for this reply, which is what I would have suspected. An ace is such a serendipitous thing that I don't know how you'd do it anyway.
I was a member of a club for 15 years that had five par threes, none longer than 160 from the back tees; probably played close to 2000 rounds there, and never had an ace. Then I was a member of a club for another 7 years that also had very short par 3's, and probably played 1000 rounds there; one hole-in-one there, with a pitching wedge. The greens at both clubs were relatively flat and relatively straightforward.
Here's the catch: I have five aces in my lifetime, so four of them have been away from the courses I know best and play the most. Not only that, but the other four have been with a four iron, a five iron, and (years later) with four and five hybrids. In other words, happy accidents from far, far away in which the hole got in the way of my ball. Literally...
So I don't think there would be much need to figure out ways to defend against an ace by the likes of me, since there's no rhyme or reason to it anyway. I know terrific golfers who are MUCH better than I who have zero aces in their lifetime. The whole thing is sort of an accident of time and space anyway.
