I've noticed on many of the Tillinghast courses I've played, he liked to include a version of the Hell's Half Acre as seen on Pine Valley's 7th (I know there is some debate as to whether or not that was Tilly's idea, but that is not the point of this thread). The point, is to see what these HHA's versions look like today, what they looked like in the past if available, and to discuss how well they work.
I've seen HHA's on 3 of Tillinghast's courses.
First is the 9th at Somerset Hills, a 530 yard par-5 that plays uphill the entire way. The HHA should not be in play after a drive in the fairway (doesn't mean it isn't), but certainly drives in the rough may be forced to lay-up.
The next example I've seen is at the 14th at Quaker Ridge in NY. Like the hole at Somerset Hills, this hole is a mid-length par-5 that plays uphill. Here the HHA is set closer to the green meaning drives in the rough/bunkers are almost forced to lay-up and even players in the fairway must consider carefully the option of laying up.
Finally, the 14th at Baltimore CC (East) is a gargantuan par-5 that plays over 600 yards from the back tees. Here the HHA is considerably longer than at the other holes mentioned -- approximately 65 yards in the air to carry.
