Snooker ( /ˈsnʊkər/ or /ˈsnuːkər/) is a cue sport that is played on a large green baize-covered table with pockets in each of the four corners and in the middle of each of the long side cushions. A regular (full-size) table is 12 × 6 ft (3.7 × 1.8 m). It is played using a cue and snooker balls: one white cue ball, 15 red balls worth one point each, and six balls of different colours: yellow (2 points), green (3), brown (4), blue (5), pink (6) and black (7).^[1] A player (or team) wins a frame (individual game) of snooker by scoring more points than the opponent(s), using the cue ball to pot the red and coloured balls. A player wins a match when a certain number of frames have been won.
Snooker, generally regarded as having been invented in India by British Army officers, is popular in many of the English-speaking and Commonwealth countries,^[2] with top professional players attaining multi-million pound career earnings from the game.^[3] The sport is particularly and increasingly popular in Japan and China.^[4]

[edit] History

Main article: History of snooker

It is commonly accepted that snooker originated in the later half of the 19th century.^[5] Billiards had been a popular activity amongst British Army officers stationed in India, and variations on the more traditional billiard games were devised. One variation, devised in the officers' mess in Jabalpur during 1874^[6] or 1875,^[5] was to add coloured balls in addition to the reds and black which were used for pyramid pool and life pool.^[7] The word snooker also has military origins, being a slang term for first-year cadets or inexperienced personnel.^[5] One version of events states that Colonel Sir Neville Chamberlain of the Devonshire regiment was playing this new game when his opponent failed to pot a ball and Chamberlain called him a snooker.^[7] It thus became attached to the billiards game now bearing its name as inexperienced players were labelled as snookers.^[8]
The game of snooker grew in the latter half of the 19th century and the early 20th century, and by 1927 the first World Snooker Championship^[5] had been organised by Joe Davis who, as a professional English billiards and snooker player, moved the game from a pastime activity into a more professional sphere.^[9] Joe Davis won every world championship until 1946 when he retired. The game went into a decline through the 1950s and 1960s with little interest generated outside of those who played. In 1959, Davis introduced a variation of the game, known as snooker plus, to try to improve the game's popularity by adding two extra colours. However, it never caught on.
A major advance occurred in 1969, when David Attenborough commissioned the snooker tournament Pot Black to demonstrate the potential of colour television, with the green table and multi-coloured balls being ideal for showing off the advantages of colour broadcasting.^[10][11] The TV series became a ratings success and was for a time the second most popular show on BBC Two.^[12] Interest in the game increased and the 1978 World Championship was the first to be fully televised.^[2][13] The game quickly became a mainstream sport^[14] in the UK, Ireland and much of the Commonwealth and has enjoyed much success in the last 30 years, with most of the ranking tournaments being televised. In 1985 a total of 18.5 million viewers watched the concluding frame of the world championship final between Dennis Taylor and Steve Davis.^[15] In recent years the loss of tobacco sponsorship has led to a decrease in the number of professional tournaments, although some new sponsors have been sourced;^[16] and the popularity of the game in the Far East and China, with emerging talents such as Liang Wenbo and more established players such as Ding Junhui and Marco Fu, bodes well for the future of the sport in that part of the world.^[4][17]

[edit] The game

Main article: Rules of snooker

Snooker table with balls placed in their starting positions

Game in progress on a half-size table. A red ball about to be potted.

The object of the game is to score more points than the opponent by potting object balls in a predefined order. At the start of a frame, the balls are positioned as shown and the players take it in turns to hit a shot in a single strike from the tip of the cue, their aim being to pot one of the red balls and score a point. Whenever a red ball is potted, the shooter is allowed to pot one of the colours. If successful, they score the value of the colour potted, and it is returned to its correct position on the table. This process continues until they fail to pot the desired ball, at which point their opponent comes back to the table to play the next shot. The game continues in this manner until all the reds are potted and only the 6 colours are left on the table; at that point the aim is to pot the colours in the order yellow 2, green 3, brown 4, blue 5, pink 6, black 7, with the balls not being returned to play. When the final ball is potted, the player with the most points wins.^[1]
Points may also be scored in a game when a player's opponent fouls. A foul can occur for numerous reasons, such as hitting a colour first when the player was attempting to hit a red, potting the cue ball, or failing to escape from "a snooker" (a situation where the previous player finished their turn leaving the cue ball in a position where the object ball cannot be hit directly). Points gained from a foul vary from a minimum of 4 to a maximum of 7 if the black ball is involved.^[1]
One game, from the balls in their starting position until the last ball is potted, is called a frame. A match generally consists of a predefined number of frames and the player who wins the most frames wins the match overall. Most professional matches require a player to win five frames, and are called 'Best of Nine' as that is the maximum possible number of frames. Tournament finals are usually best of 17 or best of 19, while the World Championship uses longer matches – ranging from best of 19 in the qualifiers and the first round proper, up to 35 frames in length (first to 18), and is played over two days.^[18]
Professional and competitive amateur matches are officiated by a referee who is the sole judge of fair play. The referee also respots the colours on to the table and calls out how many points the player has scored during a break. Professional players usually play the game in a sporting manner, declaring fouls the referee has missed, acknowledging good shots from their opponent, or holding up a hand to apologise for fortunate shots.

Other terminology used in snooker includes a player's break, which refers to the total number of consecutive points a player has amassed (excluding fouls) when at one visit to the table. A player attaining a break of 15, for example, could have reached it by potting a red then a black, then a red then a pink, before failing to pot the next red. The traditional maximum break in snooker is to pot all reds with blacks then all colours, which would yield 147 points; this is often known as a "147" or a "maximum".^[19]

Accessories used for snooker include chalk for the tip of the cue, rests of various sorts (needed often, due to the length of a full-size table), a triangle to rack the reds, and a scoreboard. One drawback of snooker on a full-size table is the size of the room (22' x 16' or approximately 5 m x 7 m), which is the minimum required for comfortable cueing room on all sides.^[20] This limits the number of locations in which the game can easily be played. While pool tables are common to many pubs, snooker tends to be played either in private surroundings or in public snooker halls. The game can also be played on smaller tables using fewer red balls. The variants in table size are: 10' x 5', 9' x 4.5', 8' x 4', 6' x 3' (the smallest for realistic play) and 4' x 2'. Smaller tables can come in a variety of styles, such as fold away or dining-table convertible.

[edit] Governance and tournaments

See also: List of snooker tournaments and Snooker organisations

The World Professional Billiards and Snooker Association (WPBSA, also known as World Snooker), founded in 1968 as the Professional Billiard Players' Association,^[21] is the governing body for the professional game. Its subsidiary, World Snooker, based in Bristol, England, organises the professional tour. Over the years the board of the WPBSA has changed many times, which some argue is an indication of in-fighting within the sport.^[22][23][24] The amateur game is governed by the International Billiards and Snooker Federation (IBSF).^[25]
Professional snooker players can play on the World Snooker main tour ranking circuit. Ranking points, earned by players through their performances over the previous two seasons, determine the current world ranking.^[26] A player's ranking determines what level of qualification they require for ranking tournaments. The elite of professional snooker is generally regarded as the "Top 16" ranking players,^[27] who are not required to pre-qualify for any of the tournaments.^[28] The tour contains 96 players – the top 64 from the previous two seasons, the 8 highest ranked professional players on the Players Tour Championship Order of Merit who are not in the top 64, 12 players from the Q School, and various regional, junior and amateur champions.^[29]
The most important event in professional snooker is the World Championship,^[30] held annually since 1927 (except during the World War II and between 1958 and 1963). The tournament has been held at the Crucible Theatre in Sheffield, England since 1977, and was sponsored by Embassy from 1976 to 2005.^[16] Since 2005, tobacco companies have not been allowed to sponsor sporting events in the United Kingdom, and the World Championship had to find a new sponsor. It was announced in January 2006 that the 2006–2010 world championships would be sponsored by online casino 888.com. The Championship is currently sponsored by BetFred.com after 888.com pulled out of their five year sponsorship deal after three years.^[31] On 15 April 2009 the World Snooker Championship website announced that Betfred.com would be the new sponsor of the World Championship for the next four years.^[32][33]
The status of winning the World Championship is great, and it is the most highly valued prize in professional snooker,^[34] both in terms of financial reward (£250,000 for the winner)^[35] as well as prestige. The World Championship is televised extensively in the UK by the BBC^[36] and gains significant coverage in Europe on Eurosport^[37] and in the Far East.
The group of tournaments that come next in importance are the other ranking tournaments. Players in these tournaments score world ranking points. A high ranking ensures qualification for next year's tournaments, invitations to invitational tournaments and an advantageous draw in tournaments.^[27] The most prestigious of these after the World Championship is the UK Championship. Third in line are the invitational tournaments, to which most of the highest ranked players are invited. The most important tournament in this category is The Masters,^[38] which to most players is the second or third most sought-after prize.^[39]
In an attempt to answer criticisms that televised matches can be slow or get bogged down in lengthy safety exchanges and that long matches causes problems for advertisers,^[40] an alternative series of timed tournaments has been organised by Matchroom Sport Chairman Barry Hearn. The shot-timed Premier League Snooker was established, with seven players invited to compete at regular United Kingdom venues, televised on Sky Sports. Players have twenty-five seconds to take each shot, with five time-outs per player per match. While some success has been achieved with this format it generally does not receive the same amount of press attention or status as the regular ranking tournaments.
There are also other tournaments that have less importance, earn no world ranking points and are not televised. These can change on a year-to-year basis depending on calendars and sponsors.

[edit] Equipment

This section requires expansion with: a sentence or two about the balls & table; link to the main articles on these topics..

Chalk and cue.

Chalk

The tip of the cue is 'chalked' to ensure good contact between the cue and the cue-ball.

Cue

A stick, made of wood or fibreglass, the tip of which is used to strike the cue-ball.

Extension

A shorter baton that fits over, or screws into, the back end of the cue, effectively lengthening it. Is used for shots where the cue-ball is a long distance from the player.

Rest

A stick with an X-shaped head that is used to support the cue when the cue ball is out of reach at normal extension.

Rest head adaptor

An attachment that slips onto a conventional rest head to make a spider or just to give a slightly different bridge.

Hook rest

Identical to the normal rest, yet with a hooked metal end. It is used to set the rest around another ball. The hook rest is the most recent invention in snooker.

Spider

Similar to the rest but with an arch-shaped head; it is used to elevate and support the tip of the cue above the height of the cue-ball.

Swan (or swan-neck spider)

This equipment, consisting of a rest with a single extended neck and a fork-like prong at the end, is used to give extra cueing distance over a group of balls.

Triangle/Rack

The piece of equipment is used for gathering the red balls into the formation required for the break to start a frame.

Extended rest

Similar to the regular rest, but with a mechanism at the butt end which makes it possible to extend the rest by up to three feet.

Extended spider

A hybrid of the swan and the spider. Its purpose is to bridge over large packs of reds. Is less common these days in professional snooker but can be used in situations where the position of one or more balls prevents the spider being placed where the striker desires.

Half butt

Usually housed underneath the side of the table, the half butt is a combination of a table length rest and cue which is rarely used unless the cue ball needs to be struck in such a way that the entire length of the table is the actual obstacle.

Ball marker

A multi-purpose instrument with a 'D' shaped notch, which a referee can (1) place next to a ball, in order to mark the position of it. They can then remove the ball to clean it; (2) use to judge if a ball is preventing a colour from being placed on its spot; (3) use to judge if the cue ball can hit the extreme edge of a "ball on" when awarding a free ball (by placing it alongside the potentially intervening ball).

[edit] Notable players

In the professional era that began with Joe Davis in the 1930s and continues up until the present day, a relatively small number of players have succeeded at the top level.^[41] Reaching and maintaining a place amongst the snooker elite is a tough task, with the standards of the game being such that it requires many years of dedication and effort as well as natural ability.^[42]
Certain players have tended to dominate the sport through the decades. John Pulman is generally regarded as the principal player through the 1960s, Ray Reardon through the 1970s, Steve Davis through the 1980s and Stephen Hendry through the 1990s, winning 6 (1970, 1973–76 and 1978), 6 (1981, 1983, 1984 and 1987–89) and 7 (1990, 1992–96 and 1999) World Championships respectively. No one dominated in the 2000s, however Ronnie O'Sullivan winning the title on three occasions (2001, 2004 and 2008) and Mark Williams and John Higgins winning twice (2000, 2003 and 2007, 2009 respectively). Higgins has four world titles in total, having won his first title in 1998 and his fourth in 2011. Last successful title defence was in 1996 when Hendry won the sixth of his seven titles (and 5th in a row).^[43]
