Mark!
Yes I played it (Old) this summer and thought it was very, very good. I am so glad to find someone with whom to discuss -- blast that search engine!
The starting five is fantastic. The opener for example is a neat lesson in angles -- I think that left-side fairway bunker is new (it's not in the posted Google aerial) but regardless improves the decision off the tee. Come as close as you dare for a go-for-it angle.
Here's a post on the 8th from this summer:
The ingenious use of slope and mounding on the 8th at Golf Club de Belgique. This par 4 turns sharply left around 210 yards. A shelf roughly 15 yards wide on the left falls off a good 10 yards to the outside of the dogleg.
The mounding provides the brilliance: a golfer who lands on the shelf has a clear view to the green, but the one who misses the shelf will face a second shot made blind by the mounds, which are only a few feet high but effective due to fall off in the fairway.
So the genius is not the generic use of mounds but the designer's conception of them as a solution to the problem of using this wonderful topography (which of course is the sign of someone who knew how to route a course) like a "POV hazard."
16, 17, and 18 are very good in their own right -- and as a finisher an excellent example of how to give good (match-play) rhythm to the close: gamble, hard, gamble. This is TOC-like. Individually, 16 seems to be the hole that gets the ink, such as the course gets any, but for my money 8 and 17 are the ones to really study.
The holes on uninspired land hold it back, but 1-5, 8, and 16-18 for me make it a course worth returning to. (In fact, were the weather not so poor last week I might have had a go.) The
apres-golf, in a lovely chateau, is icing on the cake, as is the arboretum quality of the course, something that normally does nothing for me but here it works for some reason. (The king actually wanted the course to double as an arboretum.)
Please do share your impressions.
