thats the one, and my copy is less than 6 months old!
The part that I found initially confusing was that all three types (strategic/penal and heroic) will be found on a golf course, if you look for them. At times, the golden age architects are portrayed (to a novice) as 100% strategic whereas their predecessors were 100% penal. Probably a change in balance/emphasis of style in reality.
Not sure what you prceed to in the second lesson. There might be some guide from Doak's book. In my case, I wanted to know what the hell is a Redan, Alps, Biarritz, Short, Long etc etc (remember, I'm from Oz, so I understand something of MacKenzie, but don't have a clue about Ross, Flynn, Raynor, Colt, MacDonald, Crump etc etc). I'm encouraged to pursue and value false fronts and short grass after getting an understanding of these concepts.
I reckon the aerial of the National (NGLA) would probably be a good third lesson. Saw that for the first time the other day. I've got to print that one soon and look at it in detail. Perhaps throw in a few other classic holes that they would know. Easier to understand the concepts on famous holes (Riveira #10).
have fun. Hope these juvenile ramblings help.
