The Grove XXIII (the Roman numeral represents the number Jordan wore with the Chicago Bulls) twists in an ingenious double-helix routing that can be played in four nine + nine combinations, and in shorter three- to six-hole loops. The key to the flexibility is the clustering of greens and tees, and a crossover junction after the fourth and 13th holes. Walking off the fourth green, for instance, play can continue on at the fifth, or it can switch over to the 14th and finish in the opposite direction, so each nine can be broken into sections. In fact, it’s possible to play continuous internal circuits without ever returning home, enhancing the likelihood of ongoing presses, overtimes and emergency holes.
