What must players do if they agree to allow one to play out of turn?

When players agree to allow one player to play out of turn, they are establishing a mutual understanding that the play will proceed without concern for the typical turn order of play. In this scenario, the stipulated rules regarding turn-taking are relaxed, meaning that the action taken to allow this is valid and does not incur any penalties.

This is consistent with the overall principles in golf where players retain some level of autonomy and responsibility for their pace of play and agreements amongst themselves. Allowing a player to play out of turn is a common practice when it can help facilitate the game flow, particularly in casual situations or when an agreed-upon arrangement can enhance the enjoyment of the game.

Thus, players who engage in this agreement can play without facing any repercussions related to turn order, allowing them to enjoy the game without the added stress of strict adherence to the rules in this specific aspect.
