Alternate Greens

Definition: When two different greens are constructed for the same golf hole, the hole is said to have "alternate greens." This is unusual, but not unheard of, on 18-hole courses. However, where alternate greens are more often (but still infrequently) used is on 9-hole courses. Golfers might play to one set of greens (say, marked with blue flags on the pin) during the first nine, and the second set of greens (say, marked with red flags) on the second round. In that way, the 9-hole course offers a different look on the second go-round.
