The 15th is, of course, the famous Redan, a hole that has been described, analyzed, copied (to some degree), “improved upon (?)," and photographed on countless occasions. Here is my take.
A par 3 of 190 yards in total, the 15th is not your typical one-shot hole. For starters, a large ridge sits 50 yards short of the green and conceals the putting surface’s right side from anyone less than 30 feet tall. However, this visual obstacle is secondary to the challenge presented by the principal slope of the green, tilting away and to the left. Fortunately, on this day the flag was visible above the left foreground bunker to provide some sense of direction.
Zooming in, it is possible to discern the left leading edge of the green but still difficult to figure the exact pin position on a green that measures 45 yards from front/right to back/left.
Bunkers cut into foreground ridge are quite formidable but thankfully inconsequential to all but the worst of tee shots.
Beyond the ridge, looking at the front/right corner of the green, one observes the swale leading up to Putter Land next to the deeply-sunken bunker at the left front corner.
For those hoping to play long and avoid trouble, punishment awaits in the form of a sandy triumvirate set beyond the right side of the green. A properly-clubbed shot drawing to the left will run with the predominant slope of the green and bring birdies into play, while a high cut will stop at the entrance to the green and leave a testing downhill chip or putt.
