1.2 Ask Rule
HGA Local Rule 1.2: Ask Rule. A player can ask opponents for relief from unmarked "ridiculously" bad areas of the course, but opponents are not obligated or encouraged to grant it! Just remember you might be in a worse position somewhere else in the round when you might want to use the "Ask Rule."
The Ask Rule was established to better reflect conditions on the PGA tour. Only once has the HGA encountered a tournament site where all sprinkler heads, bad areas of the course were properly marked. While the Ask Rule was not designed for every divot and bad area it was designed for bad areas of the course left unmarked for more than 1 day.
