Definition of Collar

This is an imaginary player that you can attempt to run a rack against when playing a practice or training game.

A 7 inch (17.8 cm) square box drawn on a balkline table from the termination of a balkline with the rail, thus defining a restricted space in which only 3 points may be scored before one ball must be driven from the area. It developed to curtail the effectiveness of the chuck nurse, which in turn had been invented to thwart the effectiveness of the Parker's box in stopping long, repetitive runs using the anchor nurse.

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).

This shot is a minimally calculated distressed shot which makes it evident to the opponent you no longer have any hope to winning the game.

This a shot that hits the object ball at the nine ball to see if you can get lucky by sinking the nine ball in any pocket. (also see Cheese the Nine and Rolling the Cheese).

Same as foot spot. Chiefly British today, but also an American usage ca. World War I.

Slang term for the cue ball.

Shooting at an object ball that is already in motion at the moment of shooting and cue ball impact; illegal in most games and usually only seen in exhibition/trick shots.

A bridge formed by the hand where no finger loops over the shaft of the cue. Typically, the cue stick is channeled by a "v"-shaped groove formed by the thumb and the base of the index finger.

Australian: Defeated with all seven of one's object balls (in blackball or eight-ball) remaining on the table.

Principally British: In snooker, if a player wins a match without the need for the final session to be played (for example, if a player wins a best-of-25-frames match split into three sessions - two sessions of eight frames and one of nine - by a margin of say, 13 frames to 3), then they are said to have won the match "with a session to spare".

Same as position. "She got good shape for the next shot". See also position play, leave.

A cue made specificaly for an individual player. The term may also describe a quality product of a low volume yielding cue maker who puts more time and effort into both the design and structural integrity of the cue stick, as opposed to a cue manufacturer that builds their cues in a more assembly line fashion.

Deviation of a ball from its initial direction of travel. Often the result of a poor-quality table and may be an artifact of the cloth, the bed, a ball with uneven weight distribution, or simply the floor the table stands on being uneven.

One-on-one game play.

A deliberate foul that leaves the balls in a safe position, reducing the risk of giving a frame-winning chance to the opponent. The miss rule in snooker was implemented primarily to discourage the professional fouls.

A type of safety shot in the middle of a safety exchange that is not intended to put the opponent in a difficult situation regarding their next safety, but rather played so as to not leave an easy pot on. A typical example in snooker, which sees the most shots of this kind, is a slow roll-up into the pack.

The 'Lady Jane Grey' is a rarely used term to describe a shot in the game of snooker. The cue ball is baulk side of the spotted black after potting a red ball. The black is powerfully potted into a top corner pocket and the cue ball bounces off the top cushion into the red balls, moving them into space, thus allowing the continuation of a break. Named after Lady Jane Grey, the 16th Century Queen of England, possibly because the speed the cue ball must be hit matches the speed with which she was deposed from the throne.

Used in snooker in reference to the position of the cue ball. It is above the object ball if it is off-straight on the baulk cushion side of the imaginary line for a straight pot (e.g. "he'll want to finish above the blue in order to go into the pink and reds"). It is also common to use the term high instead.

This is a relatively simple machine that is used to duplicate inlay cuts within a cue so that the sizing will be accurate. When compared to the technical CNC machines, this is more like a tape measure, but when this effective tool is used to inlay a cue stick, you are getting a cue with genuine handcrafted inlays.

This is a style of playing a pool game with a partner playing on your team. You can either take turns or play in a tag team style. This works well when there are a lot of people around that want to play.
A form of team play in which two players compete against another team of two players in any given frame or match. In a doubles game, the first player from the breaking team is the only one who shoots during the opening inning, with control of the table passing to a member of the opposing team at the end of that inning, then upon the end of the opponent's inning to the doubles partner of the original player, and next to the second opponent, play proceeding in this doubly alternating manner until concluded. Contrast Scotch doubles.

In snooker, the pocket nearest the yellow spot.

This refers to a shot that is not banked, does not hit a rail and goes into the pocket without contacting any other balls on the table.

A geometric form, usually aluminum, wooden or plastic, used to assist in setting up balls in games like eight-ball, nine-ball, and snooker. The rack allows for more consistently tight grouping of balls, which is necessary for a successful break shot. In most games a triangle-shaped rack capable of holding fifteen balls can be employed, even if the game calls for racking less than a full ball set, such as in the game of nine-ball. For further information, see the Rack (billiards) main article.
In some games, refers to a single frame.
