Michael D,
How is #1 in your post there not the identical definition someone might write about "penal architecture"?
How is "strategic" not just one end of the continuum on which "penal" is the other end?
Just different degrees on the same theme...a theme that likely is more exciting the closer to the "penal" end you get...not necessarily better, just more exciting...
In my mind, bona fide penal architecture never truly "rewards."
If there is no advantage to be had by "flirting" with a hazard, or if there is no advantage to hitting your tee shot to the right side of the fairway, or the left side of the fairway, I don't think you can call the hole, or the placements of the hazards "strategic."
I like to think about it like this. To my eye you are asked to "tackle" or "strategize" a hole in fundamentally different ways if you posit a hole with bunkers lining both sides of the fairway versus one where you have one bunker directly in the middle of the fairway.
One type asks the golfer to consider one and one possibility only. Miss the bunkers or else.
The other asks the golfer to consider numerous possibilities. Blast it over the bunker, lay up short, go right, go left. Add to this greenside bunkers which clearly dictate what angle is preferable in an approach shot and you have the makings of a strategic hole.
I also think strategy can be integrated into a golf hole without sand or water hazards. As Tom Doak has mentioned a million and one times, short golf grass and undulations around greens seem to be most vexing to many golfers.
my two bits.....
