Amateur vs. Pro
Amateur golfers play the game without monetary gain. An amateur may forfeit his status and be labeled a professional for:
Receiving compensation for serving as a professional golfer or as teaching or playing assistant to a professional golfer.
Playing for prize money.
Lending one's name or likeness for use in any way for the advertisement or sale of anything, regardless of whether the product is used in, or pertains to, golf.
Because of golfing skill or reputation, accepting compensation for making a personal appearance, whether or not in connection with a golf competition or exhibition.
