I honestly don't know by how much the greens at Beau Desert may have been toned down. There is still at least one idiosyncratic green, the 5th, which is on three levels, front to back, highest in the middle! I seem to recall that the approach to the 17th was simplified - possibly the slopes on the approach rather than the putting surface? I'll enquire - one of the members with whom I've played is the club's honorary historian.
On another tack, somewhere in recent correspondence on your site I was asked about other holes inspired by Moortown's 'Gibraltar' which I stated had been much copied. My apologies to whoever asked that question for not answering more personally - I can't find his post! Mackenzie described the hole in some detail in 'Golf Architecture' and when it was built it attracted many spectators, largely because it was the first artificially constructed hole (or, at least, one of the earliest such holes). The slopes tend to throw the imperfectly struck ball into bunkers front left or back right and Mackenzie described the front bunkers as having, 'very much the same effect as a cross bunker without the hardship to the long handicap player.' The hole most obviously inspired by 'Gibraltar' is the 11th at Alwoodley, which appears as a proposed new hole on Mackenzie's map of about 1910, described, 'Suggested new 11th hole of a similar type to 17th at Moortown.' ('Gibraltar' was at first No 17, later No 8, and is now, I think, No 10 at Moortown). I am told that the 4th on the East Course at Royal Melbourne (formerly 16th on Composite Course, currently 8th) was also inspired by it, calling for the same variety of shots, ranging from a running shot drawn round behind the bunkers front left to a high fade landing softly. Was this a Mackenzie hole or a Russell one, I wonder? The 12th at The Jockey Club in Argentina is another candidate but, as with Royal Melbourne, I have no first-hand knowledge. As first built, the 12th on the High Course at Moor Park was pretty well a mirror image of 'Gibraltar', giving the left-handed player the same options. At some point in the 60s or 70s the bunkering was simplified and the green now presents a more open target.
Do your correspondents know of other examples?
