What term would indicate that an action is suggested but not enforced in the Rules of Golf?

The term that indicates an action is suggested but not enforced in the Rules of Golf is "should." This term conveys that while the action is advisable or recommended, it does not impose an obligation on the player. In this context, "should" serves as guidance, allowing flexibility rather than mandating compliance.

Other terms, like "must," imply a requirement that players are obligated to follow without exception. "May" offers players the option to take action, indicating permission but without the advisory connotation of "should." "Deemed," however, refers to a determination or classification and does not pertain to recommendations or suggestions. Thus, "should" accurately reflects the essence of advisory actions within the framework of the Rules of Golf, allowing players to decide based on circumstances.
