When definitions fall apart under any scrutiny at all, the problem lies with the definitions themselves and not with the people cross-examining them. There's been a long-upheld false dichotomy on this site between the words "strategic" and "penal." With even a small amount of critical analysis, it becomes clear that they're not mutually exclusive (at least as defined by Cornish and Whitten and when that definition is applied as it has been on this thread) and often part and parcel of the totality of how a hole functions.
Part of the problem with the C&W definition is that it doesn't offer a way to describe a feature with any more depth than we have without the word. If "penal" is synonymous with "forced carry" or "compulsory," then it's really just a redundant word. Language works best when depth is gained by additions to the lexicon, and the type of scholarship in which we're allegedly engaged on this site works best if we have terminology that allows us to explore concepts more deeply as opposed to jargon that dumbs our discussions down with redundancy.
This is why I've always preferred Kyle Harris' definition of a strategic feature. To paraphrase, he suggested that strategic features are those which are located in direct proximity to or in what would otherwise be the ideal location for a shot, while penal features are those located in a position that, absent the feature, would still be the incorrect spot to be. That lends far more depth and requires far more knowledge and analysis than simply identifying a feature that is compulsory. It also is far more reflective of the actual definition of strategy as it pertains to how golfers approach a hole.
My understanding of hole 15 from reading this thread is that "Position A" for the player who can't reach the green in two is in direct proximity to the water on the left side of the fairway, creating an angle that effectively makes the green deeper and gives plenty of room to miss long. Furthermore, if the pond were filled in and maintained as fairway, position A would probably be somewhere on top of the fill where the lie would inevitably level and the pitch would be into the slope of the green. By that definition, a hazard placed in the area of the pond becomes a strategic one, which it clearly is based on the options it presents from inside 250 yards (go for the green, lay up to wedge yardage on a downslope, or challenge the water on the left side to find a flat spot to pitch from, and then on the subsequent shot choose whether or not to go at the flag, the fat part of the green, or bail out long and right).
I might reconsider the above if someone could do what I asked in my last post and explain:
How do you reconcile that the plethora of strategic options available from 250 yards and in on Augusta's 15th are all made valid by the existence of a single feature that fits the C&W definition of "penal"?
I don't think anyone will be able to do that though. The bottom line is that the feature drives the strategy of every golfer who plays the hole. Do with that what you will. You can call it strategic, penal, heroic, or any other word you wish to use. A rose by any other name would still smell sweet to the guy who handles it wisely and prick with thorns the guy who plays stupidly.
