Question: If a golfer has ever played golf for money or received payment for giving instruction s/he may no longer be considered what type of golfer?
About the article "Golf", section "Rules and regulations".

Candidate passages:
The rules of golf are internationally standardised and are jointly governed by The R&A, spun off in 2004 from The Royal and Ancient Golf Club of St Andrews (founded 1754), and the United States Golf Association (USGA).
The underlying principle of the rules is fairness.
As stated on the back cover of the official rule book:
"Play the ball as it lies, play the course as you find it, and if you cannot do either, do what is fair.
"
There are strict regulations regarding the amateur status of golfers.
Essentially, anybody who has ever received payment or compensation for giving instruction, or played golf for money, is not considered an amateur and may not participate in competitions limited solely to amateurs.
However, amateur golfers may receive expenses that comply with strict guidelines and they may accept non-cash prizes within the limits established by the Rules of Amateur Status.
In addition to the officially printed rules, golfers also abide by a set of guidelines called golf etiquette.
Etiquette guidelines cover matters such as safety, fairness, pace of play, and a player's obligation to contribute to the care of the course.
Though there are no penalties for breach of etiquette rules, players generally follow the rules of golf etiquette in an effort to improve everyone's playing experience.
Golf instruction can be divided into two approaches.
That which constitutes more than 90% of today's golf instruction is body-focused.
The central premise of this type of golf instruction is built around the idea that if the golfer learns to correctly move various body parts (hips, legs, shoulders, etc.)
the result will be a movement of the golf club that will produce effective golf shots.
That which constitutes the other 10% of golf instruction is club-focused.
Its central premise is that the golfer should instead focus on learning how the golf club should move during an effective swing.
De la Torre has devoted his career to refining and teaching this approach to both golfers and instructors.
The difference between these two approaches may seem minor at first consideration.
However, any student (or instructor) who has experienced both will immediately appreciate the simplicity of de la Torre's golf instruction which is unique among the leading golf instructors.
De la Torre brings to light the absurdity of thinking that the cause of a poor shot is related to what your body is doing (e.g.
Hips are too fast, arms are too slow, shoulder turn is off plane, etc.)
He correctly observes that if the club is moving correctly, there is nothing you can do with your body that produce a poor shot.
Conversely, if the club is moving incorrectly, there is nothing you can do with your body that will correct the problem and avoid the poor shot.
By way of analogy, regardless of what he does with his body, if the marksman does the right thing with the rifle, the bullet must hit the target.
If the golfer does the right thing with the golf club, the ball must go to the target.
Not only does this approach identify and deal with the single factor that determines the outcome of each shot (i.e.
the movement of the golf club), it enables the golf instruction to be highly simplified.
For beginners, this means golf is far more comprehendable and achievable.
For experienced golfers, his instruction has been a relief from their efforts to manage the many parts of the body and therefore a lifting of the unnecessary burden carried by too many golfers.
For tour professionals, this simplicity enables a more manageable swing that better withstands the pressures of competition.
He therefore has made a life's career and many satisfied clients by diagnosing and then fixing the motion of the club.
Body-focused instruction is problematic because:  no two golfers' bodies are exactly alike,  it asks golfers to consciously control body motions that are by their nature unconsciously controlled,  it asks the golfer to address too many things during the 2.5 seconds required for a golf swing, and  demands that all body motions be correct in order to achieve the desired result.
By contrast, club-focused instruction teaches:  how the club moves for an effective swing,  the club's movement is universal for every player and every club, and  a lesson simple enough to accomplish during those same 2.5 seconds.  
In golf the distinction between amateurs and professionals is rigorously maintained.
An amateur who breaches the rules of amateur status may lose his or her amateur status.
A golfer who has lost his or her amateur status may not play in amateur competitions until amateur status has been reinstated; a professional may not play in amateur tournaments unless the Committee is notified, acknowledges and confirms the participation.
It is very difficult for a professional to regain his or her amateur status; simply agreeing not to take payment for a particular tournament is not enough.
A player must apply to the governing body of the sport to have amateur status reinstated.
Under the rules of golf and amateur status of the R&A, the maximum an amateur can win is £500.
Under the rules of golf and amateur status of the USGA the maximum an amateur can win is $750.
If an amateur accepts a prize of greater than this they forfeit their amateur status, and are therefore by definition a professional golfer.
Professional golfers are divided into two main groups, with a limited amount of overlap between them:  The great majority of professional golfers (at least 95%) make their living from teaching the game, running golf clubs and courses, and dealing in golf equipment.
In American English the term golf pro refers to individuals involved in the service of other golfers.
The senior professional golfer at a golf club is usually referred to as the club professional, but at a large golf club or resort with several courses his job title is likely to be director of golf.
If he or she has assistants who are registered professional golfers, they are known as assistant professionals.
A golfer who concentrates wholly or nearly so on giving golf lessons is a teaching professional, golf instructor or golf coach.
Most of these people will enter a few tournaments against their peers each year, and occasionally they may qualify to play in important tournaments with the other group of professional golfers mentioned below.
Many club and teaching professionals working in the golf industry start as caddies or a general interest in the game, finding employment at golf courses and eventually moving on to certifications in their chosen profession.
These programs include independent institutions and universities, and those that eventually lead to a Class A golf professional certification.
A much smaller but higher profile group of professional golfers earn a living from playing in golf tournaments, or aspire to do so.
Their income comes from prize money and endorsements.
These individuals are referred to as tournament pros, tour professionals, or in American English as pro golfers.
See professional golf tours for further details.
Historically the distinction between amateur and professional golfers had much to do with social class.
In 18th and 19th century Britain, golf was played by the rich for pleasure.
The early professionals were working class men who made a living from the game in a variety of ways: caddying, greenkeeping, clubmaking, and playing challenge matches.
When golf arrived in America at the end of the 19th century it was an elite sport there too.
Early American golf clubs imported their professionals from Britain.
It was not possible to make a living solely from playing tournament golf until some way into the 20th century (Walter Hagen is sometimes considered to have been the first man to have done so).
In the developed world, the class distinction is now almost entirely irrelevant.
Golf is affordable to a large portion of the population, and most golf professionals are from middle class backgrounds, often the same sort of backgrounds as the members of the clubs where they work or the people they teach the game, and educated to university level.
Leading tournament golfers are very wealthy; upper class in the modern U.S. usage of the term.
However in some developing countries, there is still a class distinction.
Often golf is restricted to a much smaller and more elite section of society than is the case in countries like the U.S. and the UK.
Professional golfers from these countries are quite often from poor backgrounds and start their careers as caddies, for example, Ángel Cabrera of Argentina, and Zhang Lian-wei who is the first significant tournament professional from the People's Republic of China.
In various countries, Professional Golfers' Associations (PGAs) serve either or both of these categories of professionals.
There are separate LPGAs (Ladies Professional Golf Associations) for women.
