Mike and TEP,
Happy New Year!
I suspect Mike is continuing the idea I started in my fw width thread and carrying it to bunkers. Basically, I doubt anyone here would argue that the trend to fairness IS happening and that most golfers would agree with Mike that if they get in a bunker with NO chance of recovery (vs. perhaps a 50% chance) they don't like, it, AND it MAY actually contribute to LESS strategy and overall golf enjoyment.
How so?
If there is no penalty in a bunker, you will challenge it all day.
If there is a virtually guaranteed penalty of two strokes through buried lies, or unplayable lies from being up a jagged (or other, but the jagged dramatically increases the chances of that, as do tall grasses around the top edge of the bunker) the smart golfer won't be tempted anywhere near that bunker.
Rather than increase temptation, it takes it away - except for perhaps an unthinking and untalented golfer, who fires away. Then, it reduces golf enjoyment for them, and everyone with a tee time after them, perhaps to the point of outweighing whatever strategic value a few people playing that day MIGHT understand! (Seriously, playing a fast round does contribute more than a little to our enjoyment, no?)
That would make the ideal bunker somewhere in between, from a strategic standpoint.
I believe Mike is saying that a little maintenance level reduction might go a long way to make bunkers more risky than they are now, but wholesale non raking, ragged edge, long grass bunkers may not be the answer, as he presumes some presume on this site. (Follow that?)
He may also think that from a strategic variety standpoint, a mixture of bunkers you could categorize (generally, no formula necessary, but descriptive words are) from 0% (but more likely 50%) to 100% chance of full stroke or more penalty would be desireable on most coures.
As an example, my son's first approach shot at Sand Hills (from 140 yards after a 400 yard tee shot, downwind, catch the roll, etc, but still damn impressive!) found the right bunker, and he took three to get out. Now, he didn't complain, because it is such a special course. But, who wants that no their everyday course?
I am with him, other than I don't think its limited to the tour pros. Most club members live and die with their daily scores, from what I see. I will add that no bunker philosophy needs to be in place everywhere. The jagged edges at Sand Hills are perfect. Are they as perfect when built in Georgia, where Mike plays? So perfect that (all things considered) they are the "formula bunker" we should all accept as the gold standard?
As with fw width, its a legitimate architectural theory type topic, not to be dismissed lightly and out of hand because you think the ragged edges have a better look.
