Tom:
Jeff may be right in his protests, though I don't think the dub minds three-putting as much as he minds hitting into a water hazard. But, I'm happy to accept the mantle of being accommodating. Jeff probably wouldn't think of St. Andrews as accommodating, either, with those pot bunkers and wild greens, but I steered people around The Old Course who couldn't play at all, and I dare say that is not possible on most modern designs.
Why? I think it gets down to personality. There are a lot of really good players among architects, and quite a few of them seem determined to show that they know golf better than the dub does 18 times every round. (Something like Matt Ward's definition of good architecture yesterday as only rewarding the good shot.) But the really strange thing is that even more of the architects I know who are ten-handicaps make their courses too tough. I think it's because they are trying to show good players that they know what they're talking about.
I'm not saying golf courses should be easy, or dull -- those may be more accommodating to the dub, but only until he gives up the game out of sheer boredom. You have to make a course interesting, and only real difficulties make it interesting.
