Strategy is definitely not obsolete and it's not lost, not even for that .01% although it certainly may not appear in the same ways as it did fifty plus years ago--and obviously that has much to do with the distances that .01% are hitting the ball today with all their clubs (not just the driver).
But that strategy can be brought back to those courses even if the clubs used may not be the same ones used fifty plus years ago.
The obvious way to do that (even with the older architecture) is to start to dial down on the effectiveness and consequently the reliance on the aerial option that many of that .01% has come to expect and relie on! How to do that has already been mentioned to some extent on this thread alone.
Firm up green surfaces (not necessarily green speeds but green firmness) on these courses and that .01% cannot then control their aerial shots the way they've come to expect!! And if they can't control those aerial shots they way they've come to expect, what are they going to do about it?
It's completely obvious what they're going to do! They're going to look for other options and other ways to play shots where they want them as effectively or more so than that dialed down effectiveness of their aerial shots! Obviously one of those ways is the ground game or some compromise form of it!
What Mike Cirba said about bunkering is also completely true. The strategic function and strategic effectiveness of bunkering generally, the architecture of much of it in the modern age, and certainly the maintenance of much of it with super sand consistency has basically been gutted!
There's two ways to reenhance the strategic function of bunkering (probably architecture's primary strategic expression over the history of golf). One way is architecturally, the other is through maintenance (or lack of it).
We all know that the sand floors of bunkering will probably never be allowed in this day and age to be the cuppy, iffy, strategically effective situation with the lack of maintenance it used to have so the other way to make bunkering strategically functional is architecturally.
If you hit the ball in a bunker the way to make that bunker strategically functional "architecturally" is pretty obvious! Just make that bunker "iffy" as to recoverability architecturally! That doesn't mean that you can't get out of it and recover totally, it only means that isn't guaranteed architecturally--maybe, maybe not, in other words. That "iffiness" architecturally, is going to get even that .01%'s attention real quick if their recoverability reliance starts to go down!
The same thing goes for firmness "through the green". If that .01% knows their ball is not going to end up where they land it they are forced to really start to read architecture and things like topography!
Greens are the same, if they're firm enough (very lightly "denting" not "pitch marking") those .01% are going to start to look for other ways to control their ball like contours in those greens to play the ball off of for both rollout and break with their approach shots just like they did at Southern Hills at the Open a few years ago.
Or look at some of those Australian courses in the last few years!! The greens were very firm, dialing down on the effectiveness of the aerial option, making other shots and option more used, useable and useful! Same with the real firmness on those courses "through the green". Firm that area up and the driver certainly could be used but at what risk? And the bunkering of some of those Australian (or European courses)!! The sand may have been consistent but the player ran the risk of getting his ball in one of them where the architecture of that bunker might prevent him from recovering as he'd like to! We saw plenty of the world's tour players hitting tops of bunkers and/or leaving it in them because they couldn't get enough height!
All these things can bring back strategies into real effectiveness, even though, again, the clubs being used may not be the same as they once were!
Much of this stuff, I'm calling the "ideal maintenance meld" which basically means taking all the available potential options and strategies the course can offer and "maintaining" it in such a way as no option has complete reliance over another in the mind of a golfer, even that .01%!
That's maintenace! But architects can do things architecturally as well that simply creates doubt in the minds of players, even that .01%. And in my opinion that's simply creating some "iffness" architecturally!
But do architects really have the guts to do that? I don't know, that would be their individual calls!
But that's the way to either return strategy to golf courses or create it!
I don't really think any of this is close to rocket science--but it is like a big jigsaw puzzle and all the pieces have to fit together properly--both maintenance and architecture!
And then of course, days will come when it will rain like hell and the course will naturally be a whole different equation where those .01% can go back briefly to total reliance on their aerial option and probably crucify the course score-wise!
So what? The course will dry out again, and if properly maintained it will be back to playing at it's optimum with all its architectural options maintained in such a way that no golfer can overly rely on one option or strategy over another.
That delicate balance or almost quandry as to what's most effective (or least risky) will be the inevitable return of strategy in golf and architecture--it's definitely not obsolete--just misunderstood because it really is such a big jigsaw puzzle--how maintenance needs to be to ideally "meld" into all any course's overall architectural possibilities of playability!
