Mike and Jeff, in answer to Andrew's question regarding par-five holes, "What was Mr. Tillinghast's best idea, in your opinion?," the answer that the two of you gave was basically the same, "doglegs." Although I agree in concept, I think that one needs to take it a step further than that as dogleg holes had been built and used to make holes of different pars and lengths challenging and dramatic before Tilly came along, so they weren't his idea. Now, the "Double Dogleg" was, and greatly magnifies the challenge of the fairway leading from the tee to the green complex in difficulty, choice of how to play it and the beauty of the hole.
Consider how Tilly described the changes he recommended be made to the 7th hole at Pine Valley: "As it was originally planned is shown by Fig. 1. [This in reference to a sketch he made of the hole prior to the recommended changes showing the hole as basically straight from tee to green.] It is being played so at present, and a mighty fine hole it is, too. None but the long hitter can get within striking distance of the green after his second shot, and both the drive and the second shot must be hit. An enormous area of sand extends across the course, beginning, I should say, about 325 yards from the teeing ground. The hazard must be close to 100 yards across. If it is not carried, the green is beyond range. But good as it is, some variations from the present lines will make it a far greater problem, and the change is to be made.
"Along the right of the fairway extends a wood, and cuts will be made for this new teeing ground and for the second shot. After the change the tee-shot must be played more to the left than at present, the second shot will be forced to the right, and naturally the green will open up to an approach from that side. A comparison of the two sketches reveals a marked improvement with not an alarming amount of work in sight. Already the new green has been constructed [The sketch of the new hole clearly shows the two dog-legs, left to right and then right to left.]
"It would be well for those green committees, who are prone to regard with complacency holes which are satisfying, to bear in mind that no hole is perfect. A twist here and there may work wonders. [Here again is another great idea of Tilly, Twisting the fairways, that in this case creates a double dog-leg par five.]"
