Thanks for responding, George. Sorry for asking you to repeat yourself, I just wanted you to confirm my interpretation - or was I just being lazy?
Reading through the posts again it seems clear, not sure why I was confused by anything.
My understanding: A cape green would be one that jutts out, such as the original 14th at NGLA into Bullshead Bay. It isn't necessary for the shelf or plateau green to be bordered on 2 or 3 sides by water, as we see examples of cape holes with sandy waste (or other hazards) around the front and side of the green. The 16th at Hazeltine, with water on 3 sides, is a good example of a Cape Hole.
Many people - myself included, until I saw this thread - think Cape hole refers to the risk/reward diagonal tee shot found at Hazeltine or the 18th at TPC Sawgrass. But clearly the green at Ponte Vedre is not a Cape. By the CBM/Raynor definition, it is the green and not the tee shot that defines a hole as being a cape.
OK, got it. Thanks for your patience. If it's OK, I may at some point take you up on the offer to correspond via e-mail. I've been studyng MacDonald & Raynor for some time, and may have other questions regarding NGLA. Of course, once I finally receive "The Evangelist of Golf" many of those questions may be answered.
BTW - Did you find photos of the original Cape that are be included in the book? I've never actually seen an image of the green, only text descriptions.
