Funny that you should mention something perhaps to the right of HHA that would be a high risk proposition to successfully do off a somewhat missed drive on PV's #7 to get yourself on fairway grass with a shot at the green in three off a very long shot. I thought of the same basic idea earlier today but didn't mention it to do with PV's 7th since it's not a good idea to suggest such changes to a hole on a course that has the "super respect" and "time in play" that PV does. But on another course I think that would be a great addition and "wrinkle" and you're right, it certainly would serve to increase options.
However, that kind of thing completely goes against the "conceptual grain" of what Tillinghast spoke about in his chapter on the "true three shotter"!
And that was that in no case should a "true three shotter" be reached in two shots. Tillinghast's reason was most interesting. It basically all had to do with the green design. He said a "true three shotter" basically should REQUIRE (ie demand) two really full bore long shots to get within range of a shortish shot to the green for which the green was designed, and that it was virtually impossible for an architect to design a green calling for a shortish iron while at the same time having the green able to receive a really long shot.
He basically said---in this context, the architect just cannot 'serve two masters'!
But I like your thought a lot on some other really long par five with a basic HHA concept, just not at PVGC. I like it a lot and as a total concept for the "true three shotter" never to be reached by a really long shot, what the hell did Albert W. Tillinghast really know anyway?
Not a bad question actually, since Tillinghast may've been a liar, and a hypocrite. Ask Tom MacWood about that because he's convinced that Tillie sold his architectural principles to the PGA of America in the mid 1930s!
