Definition of Object ball

This is when a ball is spotted because of a foul or a handicap.

See two-shot carry.

This is a shot where the cue ball contacts an object ball and moves it along a path, but because the cue ball is still in motion it re-contacts the object ball and pushes it in the pocket after it stops.

One-pocket (often spelled one pocket) is a two-player (or -team) pocket billiards (pool) game. The object of the game is to score points by pocketing (potting) pool balls into specific pockets. A point is made when a player makes any object ball into that player's designated pocket. The winner is the first to score an agreed-upon number of points (most commonly 8). The player making the break shot (typically after winning the lag) chooses a foot corner pocket for the rest of the game; all of that shooter's balls must be shot into that pocket. All of the opponent's balls must be made in the other foot corner pocket.

Principally British: In snooker, if a player wins all of the required frames in a match without conceding a frame to their opponent - for example, if a player wins a best-of-nine-frame match with a score of 5-0 - this is referred to as a "whitewash". This term is based on a similar term used in the card game of "patience" in the UK. However, it is not used in the context of a 1-0 winning scoreline in a match consisting of a single frame.

To determine the order of play, players (representing only themselves, or teams) each simultaneously shoot a ball from the kitchen (or in British games, from the baulk line) to the end rail and back toward the bottom rail. Whichever shooter's ball comes to rest closest to the bottom rail gets to choose who breaks the rack. It is permissible but not required for the lagged ball to touch or rebound from the bottom rail, but not to touch the side rails. Lagging is usually a two-party activity, though there are games such as cutthroat in which three players might lag. In the case of a tie, the tying shooters re-lag. The lag is most often used in tournament play or other competitions. In hard-break games like nine-ball and eight-ball the winner of the lag would normally take the break, while in soft-break games like straight pool would likely require the loser of the lag to break, since breaking would be a disadvantage.

The sides of a table's frame upon which the elastic cushions are mounted. May also be used interchangeably with cushion.

This is a method of handicapping that designates a wild ball for a lesser player to be able to pocket at any point during a game in order to win.

Same as centre pocket.

This is placed on a ball by hitting it slightly below center. This action makes the ball travel in a motion against its originally hit direction.

Same as gapper

Actual wire or string with multiple beads strung (like an abacus) used for keeping score. Points "on the wire" are a type of handicap used, where a weaker player will be given a certain number of points before the start of the game.

This is any game of pool played with money on the line. You can "put some action" on the game.

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".

The deciding match between two tied opponents. Compare hill, hill.

An outgrowth of the training template concept, a racking template is a racking tool used in place of a traditional rigid ball rack for pool or snooker balls, consisting of a very thin, e.g. 0.14 mm (0.0055 in), sheet of material such as paper or plastic with holes into which object balls settle snugly against one another to form a tight rack (pack). The template is placed, stencil-like, in racking position, with the lead ball's hole directly over the center of the foot spot. The balls are then placed onto the template and arranged to settle into their holes, forming a tight rack. Unlike with a training template, the balls are not tapped to create divots, and instead the template is left in place until after the break shot at which time it can be removed (unless balls are still sitting on top of it). Manufacturers such as Magic Ball Rack insist that racking templates are designed "to affect the balls to a minimum", and while pro player Mike Immonen has endorsed that particular brand as a retail product, as of September 2010, no professional tours nor amateur leagues have adopted that or any other racking template. Although Magic Ball Rack implies development work since 2006, other evidence suggests invention, by Magic Ball Rack's founder, in mid 2009, with product announcement taking place in September of that year.

Describes a cue ball sliding on the cloth without any top spin or back spin on it.

Also shot to nothing. A British term for a shot in which a player attempts a difficult pot but with safety in mind, so that in the event of missing the pot it is likely that the opponent will not make a meaningful contribution, and will probably have to reply with a safety. The meaning refers to lack of risk, i.e. at no cost to the player ("for nothing" or coming "to nothing"). Compare two-way shot.

A tournament format in which each contestant plays each of the other contestants at least once. In typical league team play, round robin format means that each member of the home team plays each member of the visiting team once. This format is used by BCAPL, VNEA and many other leagues.

In team match play when playing one-on-one matches, if one team is short a player, a player on that team is called back to play a second match.
For example: Team A has 6 players, Team B has 4 players. There will be five individual matches played. For the fifth match Team A can pick a player from Team B to play a second match against their fifth match player.

This refers to the cluster of balls remaining in a similar position to where they were within the break.

A unit of scoring, in games such as snooker and straight pool with numerical scoring.
A unit of scoring, in team matches in leagues that use numerical scoring instead of simple game/frame win vs. loss ratios.
Another term for knuckle / tittie.

Asian Pocket Billiard Union. The APBU is a member of the WPA.

Also massé shot. A steep curve or complete reversal of cue ball direction without the necessity of any rail or object ball being struck, due to extreme spin imparted to the cue ball by a steeply elevated cue. For Example: shooting with extreme english by holding the cue at a position of 30-90 degrees while applying left or right spin.
