Amateur matchplay is a term used in golf when two amateur players compete against each other in a head-to-head match. However, there are several synonyms that can also be used to mean the same thing. For example, one could refer to it as "amateur stroke play," which is a type of golf competition where players compete by counting the number of strokes they take to complete each hole. Another synonym could be "casual golf match," which refers to a non-professional golf game between friends or acquaintances. Additionally, "friendly golf tournament" is another option, which implies a more laid-back and social atmosphere compared to professional tournaments.
