Geoffrey,
My observations of CG are very similar to yours.
1. I too loved the road hole green at the 2nd. The 2nd hole played like a beast that day (directly into about a 10 mph wind). The approach shot played very similar to the original road hole. Fantastic green. (I felt the 11th was a version of the road hole green as well...does anyone else see this?).
2. The Redan was amazing. As you said, it rises up out of the ground making absolutely no effort to blend in with the terrain (like the redans at Yale, NGLA or Mid Ocean). But it was great in it's own way. It must have been 15,000 square feet (does anyone know for sure how big it is?). The scale of that green complex is what sticks with me.
3. I too felt that the 10th green complex ("short") had a certain similarity to the one at NGLA. Like the one at NGLA, it was "wide". I've NEVER seen a green like the short hole at NGLA, but this one was very cool. The "bathtub" feature, though not as pronounced as the one at National, was also sitting at the highest point of the green, which makes for very interesting approach shots.
4. LIke you, I loved the 12th and the Punchbowl green. I still prefer the one at National, but the 12th at Chicago was a great golf hole.
5. I felt the Eden was the weakest of the one shot holes at Chicago Golf. The green complex, perched up on the knob reminded me of the Eden at Fishers Island. Only, it was playing 140 yards (versus 175 at Fishers) and it wasn't sitting out on a wind swept ocean front peninsula. I felt it played much easier than most Eden's do. Because of this, it lacked interest for me.
Other observations about the course:
I thought the false front on 4th hole was the "longest" (measured from the fall line to the fairway) of any false front I have ever seen. Must have been 20 feet. Amazing (and terrifying, even with a wedge in your hands). Why don't modern day architects use this feature more?
I loved the double plateau green complex and the principal's nose bunker on the 6th. LOVED that hole.
The 17th, from the 465 yard tee was a MONSTER.
It was too hot the day we played, but I had mud on my ball too often. Is it always that soft at Chicago Golf, or just the way it has to be in July/Aug.?
