Definition of Tournament card

In snooker, the colour ball that is worth three points, being the second-least valuable colour behind the yellow. It is one of the baulk colours.

To intentionally miss a shot (that results in a foul) in order to create a position for the cue ball that makes it hard for the other player to execute their shot. Not to be confused with a "Safety", since a safety is a legal hit.

This is a timing device for monitoring and restricting shot times for a player.

The person in charge of the game whose primary role is to ensure adherence by both players to the appropriate rules of the game being played. Other duties of the referee include racking each frame, re-spotting balls during the course of a game, maintaining the equipment associated with the table (e.g. keeping the balls clean), controlling the crowd and, if necessary, controlling the players. Formerly sometimes referred to as the umpire.

A pocket; usually used in disgust when describing a scratch (e.g., "the cue ball's gone down the sewer").

Same as suit, predominantly in British terminology, i.e., in eight-ball either of the set of seven balls (reds or yellows) that must be cleared before potting the black. Generally used in the generic, especially in rulesets or articles, rather than colloquially by players.

A line, sometimes imaginary (especially in American pool), sometimes drawn on the cloth, that runs horizontally across the table from the second diamond (from the head rail) on one long rail to the corresponding second diamond on the other long rail. In most pool games, the opening break shot must be performed with the center (base) of the cue ball behind the head string (i.e. between the head string and head rail). The head string intersects the long string at the head spot, and delimits the kitchen (and, in European nine-ball, the outer boundary of the break box). The head string's position is always determined by the diamonds, in contrast to the similar but different baulk line, the position of which is determined by measurement from the bottom cushion (head cushion).

Nine Ball is a rotation game so a player must hit the lowest numbered ball first.
The object of the game is pocket the 9-ball on any legal shot.

The horizontal plane directly in the center of the cue ball, which when hit exactly by the cue tip should impart no follow or draw.

This is an object sometimes placed underneath the cue tip.

A term applied especially in snooker for a type of double off three cushions, e.g. around the baulk colours and into a centre pocket. Such a shot is very difficult to make and would not normally be played as anything more than a shot for nothing.

In snooker and other British usages, a break of 50-99 points (100 points or more being called a century), which involves potting at least 12 consecutive balls (i.e. the last 3 reds with at least 2 blacks and a pink, followed by all the colours).

Short for top spin, i.e. same as follow.
Chiefly British: The half of the table in which the object balls are racked (in games in which racked balls are used). This usage is conceptually opposite that in North America, where this end of the table is called the foot. In snooker, this is where the reds are racked, nearest the black spot; this is the area in which most of the game is usually played.
Chiefly American: Exactly the opposite of the above - the head end of the table. No longer in common usage.

An intentionally amateurish stroke to disguise one's ability to play.

This term is used to refer to a player missing a shot.
A widespread term in US parlance describing missing a relatively easy shot—often in the face of pressure. Can be used in many forms: "I dogged the shot"; "I hope he dogs it"; "I'm such a dog."

A common way to keep track of games won when playing for small money is to use a coin that is placed under the rail next to the diamonds on the rail. The center diamond at the head of the table is taken as zero, and each diamond from that is considered to be one game. To go 'around the world' is to beat your opponent so badly that the coin travels all the way around the diamonds on the table.

A defensive action taken when a player either has no "makeable" or "high percentage" shot or chooses to leave his opponent in a difficult situation. It is a legal shot and is not considered to be dirty pool. A safety must still conform with the rule concerning hitting the correct ball first and striking a rail afterwards. If a correct ball is accidentally pocketed while playing safe, the shooter must continue to shoot.

In the UK, one of the two pockets one either side of a pool, snooker or English billiards table halfway up the long rails.

A semicircle with an 11½ inch (291 mm) radius, drawn behind a snooker table's baulk line, centred on the middle of the line, and resembling the upper case letter "D" in shape. The "D" is also used in English billiards and sometimes also in blackball and other pool games played on British-style tables.

Also known as "Break and Dish". In pool games, when a player breaks the racked object balls, pockets at least one ball on the break, and commences to run out the remaining object balls without the opponent getting a visit at the table.

One of two sharp, jutting curves of the cushions either side of a pocket at the points where cushion and pocket meet, forming the jaws of the pockets. Also known as a point, a tittie or a horn.

Named after their innovator, legendary cuemaker George Balabushka, Bushka rings are decorative bands of material incorporated into pool cues, commonly just above the wrap area, in the form of ebony and ivory blocks, or sometimes other materials, alternating in a checked pattern.

The triangular device, generally plastic, used to group the balls in a pyramid form prior to the beginning of a game.
