Golf is a sport in which individual players or teams hit a ball into a hole using various clubs, and also is one of the few ball games that does not use a fixed standard playing area. It is defined in the Rules of Golf as "playing a ball with a club from the teeing ground into the hole by a stroke or successive strokes in accordance with the Rules."

     It is said that the first ever game of golf may have been played at the Bruntsfield Links in 1456, claimed by the history of the Edinburgh Burgess Golfing Society, now The Royal Burgess Golfing Society.

     Golf, in essentially the form we know today, has been played on Scotland's Musselburgh Links since at least 1672, while variations of the game had been played throughout the British Isles and the Low Countries of northern Europe for several centuries before that.

Anatomy of a golf course

     Golf is played on an area of land designated as the course. The course consists of a series of holes. A hole means both the hole in the ground into which the ball is played (also called the cup), as well as the total distance from the tee (a pre-determined area from where a ball is first hit) to the green (the low cut area surrounding the actual hole in the ground). Most golf courses consist of eighteen holes.

Teeing Ground

     The first stroke on each hole is hit from the Tee (officially, teeing ground), where the player can use a tee (a small wooden or plastic peg), which makes the tee shot easier. Before the modern tee came into use, early golfers often used a small pyramid of sand to hold the ball. Most courses offer a range of Tee boxes to play from depending on a player's skill or handicap, making the hole longer or shorter depending on which Tees the player starts at. Often, the different Tee boxes have names associated with degree of competence (e.g., Professional and Amateur Tees), or by sex and age (Men's, Ladies', Senior, etc.). In addition to a difference in distance, the different Tees may also eliminate or reduce the danger of some hazards for the "Forward" tees, such as water hazards. Teeing grounds on most golf courses are relatively flat, in order for the golfer to have a perfect lie for the first shot on a hole.

Fairway & Rough

     After teeing off, a player hits the ball towards the green again from the position at which it came to rest, either from the fairway or from the rough. Exceptions are short par three holes, where the second shot may lie directly on the putting green or in the rough. Playing the ball from the fairway is an advantage because the fairway grass is kept very short and even, allowing the player to cleanly strike the ball, while playing from the rough is a disadvantage because the grass in the rough is generally much longer and the player doesn't have as good of an idea as how the ball will fly out of the rough.

Hazards

     Many holes include hazards, which may be of three types: 1) Water hazards such as lakes, rivers, etc. 2) Man made hazards such as bunkers and 3) Lateral Hazards such as dense vegetation areas, bushland or gardens. Special rules apply to playing balls that come to rest in a hazard. For example, in a hazard, a player must not touch the ground with his club before playing a ball, not even for a practice swing. A ball in any type of hazard may be played as it lies without penalty. If it cannot be played from the hazard for any reason, the ball may be hit from another location, generally with a penalty of one stroke. Exactly where the ball may be played outside a hazard is governed by strict rules. Bunkers (or sand traps) are hazards from which the ball is more difficult to play than from grass. As in a water hazard, a ball in a sand trap must be played without previously touching the sand with the club.

Putting Green

     To putt means to play a stroke, usually, but not always on the green, where the ball does not leave the ground. Once on the green, the ball is putted (struck with a flat faced club which makes the ball roll along the ground) towards the hole until the ball comes to rest in the cup. The grass of the putting green (or more commonly the green) is cut very short so that a ball can roll easily over distances of several yards. The direction of growth of individual blades of grass often affects the roll of a golf ball and is called the grain. The slope of the green, called the break, also affects the roll of the ball. The cup is always found within the green (at least ten feet from the edge), and must have a diameter of 108 mm (4.25 in.) and a depth of at least 100 mm (3.94 in.). Its position on the green is not static and may be changed from day to day. The cup usually has a flag on a pole positioned in it so that it may be seen from some distance, but not necessarily from the tee. This flag and pole combination is often called the pin.

     Putting greens are not of all the same quality. Generally, the finest quality greens are well kept so that a ball will roll smoothly over the closely mowed grass. Golfers describe a green as being "fast" if a light stroke of the ball allows it to roll a long distance. Conversely, a green is termed "slow" if a stronger stroke is required to roll the ball the required distance.

Out of Bounds

     The borders of a course are marked as such, and beyond them is out of bounds, that is, ground from which a ball must not be played. If a golfer hits the ball out of the course, into the "out of bounds", the player must hit a ball from nearly the same position as the original ball was played, with a penalty of one stroke.

Other Areas

     Some areas on the course may be designated as ground under repair, or "G.U.R.". This is a part of the course where repairs are being made by greenkeepers, or there is damage to the course. A ball coming to rest in this spot may be lifted and then played from outside such ground without penalty. Certain man-made objects on the course are defined as obstructions (i.e. Distance posts, gardens etc.), and specific rules determine how a golfer may proceed when the play is impeded by these.

Driving Range

     Often there is a practice range or driving range, usually with practice greens, bunkers, and driving areas. Markers showing distances are usually included on a practice range to benefit the golfer. There may even be a practice course (which is often easier to play or shorter than other golf courses). A golf school is often associated with a course or club.

Par

     A hole is classified by its par. Par is the number of strokes that a skilled golfer should require to complete the hole. For example, a skilled golfer expects to reach the green on a par four hole in two strokes, one from the tee (his "drive"), another one to the green (his "approach"), and then roll the ball into the hole with two putts. A golf hole is traditionally either a par three, four, or five. A few par six holes now exist, but will not be found on a traditional golf course.

     The par of a hole is primarily, but not exclusively, determined by the distance from tee to green. A typical length for a par three hole is anywhere between 91 and 224 m (100 and 250 yds.), for a par four, between 225 and 434 m (251 and 475 yds.). Par five holes are typically at between 435 and 630 m (476 and 690 yds.), and untraditional par six holes are anything longer. These distances are not absolute rules. For example, it is possible that a 500 yard hole could be classed as a par four since the par for a hole is determined by its 'effective playing length.' If tee to green on a hole is predominantly downhill, it will play shorter than its physical length and may be given a lower par.

     Many 18-hole courses have approximately four par-three, ten par-four, and four par-five holes, though other combinations exist and are not less worthy than courses of par 72. Many major championships are contested on courses playing to a par of 70 or 71, and it's not rare to find a worthy test (especially in the British Isles) playing to a par of 69 or lower. In many countries courses are classified by a course rating in addition to the course's par. This rating describes the difficulty of a course and may be used to calculate a golfer's playing handicap for that individual course (see golf handicap).

Play of the game

     Every game of golf is based on playing a number of holes in a given order. A round typically consists of 18 holes that are played in the order determined by the course layout. On a nine-hole course, a standard round consists of two successive nine-hole rounds. A hole of golf consists of hitting a ball from a tee on the teeing box (a marked area designated for the first shot of a hole, a tee shot), and once the ball comes to rest, striking it again. This process is repeated until the ball is in the cup. Once the ball is on the green (an area of finely cut grass) the ball is usually putted (hit along the ground) into the hole. The idea of resting the ball in the hole in as few strokes as possible may be impeded by various hazards, such as bunkers and water hazards.

     Players walk (or drive in motorized carts) over the course, either singly or in groups of two, three, or four, sometimes accompanied by caddies who carry and manage the players' equipment and give them advice. Each player plays a ball from the tee to the hole, except that in the mode of play called foursomes two teams of two players compete, and the members of each team alternate shots using only one ball until the ball is holed out. When all individual players or teams have brought a ball into play, the player or team whose ball is the farthest from the hole is next to play. In some team events a player whose ball is farther from the hole may ask his partner to play first. When all players of a group have completed the hole, the player or team with the best score on that hole has the honor, that is, the right to tee off first on the next tee.

     Each player acts as marker for one other player in the group, that is, he or she records the score on a score card. In stroke play (see below), the score consists of the number of strokes played plus any penalty strokes incurred. Penalty strokes are not actually strokes but penalty points that are added to the score for violations of rules or utilizing relief procedures.

Golf rules and other regulations

     The rules of golf are internationally standardised and are jointly governed by the Royal and Ancient Golf Club of St Andrews (R&A), which was founded 1754 and the United States Golf Association (USGA). By agreement with the R&A, USGA jurisdiction on the enforcement and interpretation of the rules is limited to the United States and Mexico. The national golf associations of other countries use the rules laid down by the R&A and there is a formal procedure for referring any points of doubt to the R&A.

     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 can't do either, do what is fair". Some rules state that:

• every player is entitled and obliged to play the ball from the position where it has come to rest after a stroke, unless a rule allows or demands otherwise (Rule 13-1)
• a player must not accept assistance in making a stroke (Rule 14-2)
• the condition of the ground or other parts of the course may not be altered to gain an advantage, except in some cases defined in the rules
• a ball may only be replaced by another during play of a hole if it is destroyed (Rule 5-3), lost (Rule 27-1), or unplayable (Rule 28), or at some other time permitted by the Rules. The player may always substitute balls between the play of two holes.

     The Decisions on the Rules of Golf are based on formal case decisions by the R&A and USGA and are revised and updated every other year.

     There are strict regulations regarding the amateur status of golfers. Essentially, everybody 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 which 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, easiness and 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.
