I think Oakmont is strategic.
I also think most people, apparently most on here, don't see it as strategic because they always assume that strategic golf must be combined with width options---eg options of being able to choose to hit the ball in various directions. Oakmont doesn't have that on most all its holes and it never has.
But what about options of distance?
That's what Oakmont does have but pretty subtly----subtly enough, I guess, where most don't even recognize it.
If you look carefully at the way Oakmont was originally designed it's not hard to see that the basic theme on the tees of Oakmont is that golfers are constantly faced with DECIDING how much club they dare to try to hit straight!
Most all golfers are under the assumption that the longer the club you try to hit the less accurate it will inherently be.
This is the golfer perception that Oakmont's design works on hole after hole.
If one looks carefully at the original design and bunkering schemes and other flanking hazard features (ditches) of the course one can see that if a golfer hits a driver long and accurately you are able to go by or get past most all the flanking and dangerous hazard features on either side.
What is strategy but a "plan", a "scheme", a "strategem", a choice amongst various things to do such as various clubs to hit off the tee. Of course the choice to hit various clubs in various directions is certainly strategic but it's not the only kind of strategic, in my opinion.
In this way Oakmont is strategic, very strategic. It just doesn't have optional directional strategies off the tees (other than #17) but it very much does have "distance" related strategies off its tees.
I've played that course in a couple of state amateurs and enough otherwise to know what goes through the player's mind hole after hole. All day long on all the tees you are basically thinking; "I'd like to have distance but is the club I'm holding going to give me enough accuracy with the distance it can give me?"
Some people might call that penal because there are no real directional options.
I've said it before about Oakmont and I'll say it again----you could play approach shots into those greens ideally from the exact middle of every fairway.
But the question on every tee is how much distance can I go for off the tees to give me a shorter shot in from the middle of every fairway.
I call that strategic----I'd call it "distance" strategic, not "directional" strategic.
But I do recognize that perhaps many on here don't look at "strategic" that way. For them "strategic" golf is almost always completely synonymous with options of being able to choose to hit the ball in various directions.
Perhaps they should learn to reconsider the interesting "distance" strategies of Oakmont.
