Definition of Shape

Chiefly British. This is a shot in a snooker game where the first object ball hit contacts another object ball and the second one is pocketed. If both of the balls are red, or if the second ball would be on if the first ball had not been deemed free then it is an allowed shot.

Technique using different wood inlays to create picture designs on the butt of the cue.

The World Pool-Billiard Association (WPA) is the international governing body for pocket billiards (and also sactions rules and events for carom billiards games as well, in cooperation with other bodies). The group was formed in 1987, and was initially headed by a provisional board of directors consisting of representatives from the United States, Japan, Sweden, and Germany.

To intentionally hide one's "speed"; "he's on the stall."
To intentionally play slowly so as to irritate one's opponent. This form of sharking has been eliminated from many tournaments with a shot clock, and from many leagues with time-limit rules.

Slang term for the cue ball.

This is a player that will regularly loose money to a particular player that is obviously a better player.

Also called a rake. A special stick with a grooved, slotted or otherwise supportive end attachment that helps guide the cue stick - a stand-in for the bridge hand. It is usually used only when the shot cannot be comfortably reached with a hand bridge. Often shortened to bridge or called a bridge stick. An entire class of different mechanical bridges exist for snooker, called rests (see that entry for details), also commonly used in blackball and English billiards.

Same as cheating the pocket. Principally used in snooker.

In snooker, the pocket nearest the yellow spot.

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.

This term refers to a foul in snooker golf.

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 specific way of holding the shaft in your hand. The closed hand bridge is a hand bridge where the index finger wraps over the cue stick for control.

Successive games won without the opponent getting to the table; a five-pack would be a package of five games.

Literally, a pocket, but generally used in the phrases losing hazard - potting (pocketing the cue ball off another ball - and winning hazard - using the cue ball to pot another ball - the two types of legal shots that pocket balls in games in which the term is used at all, which is very few today. The term principally survives in English billiards, in which both types of shots are point-scoring. Formerly, a large number of different games made use of the two types of hazards as point scorers or losers in various different ways (thus their suggestive names). The term ultimately derives from holes or pockets in the table to be avoided, in very early forms of billiards. While the terms are disused in pocket billiards today, their lingering effect is obvious, as the vast bulk of such games focus on making winning hazards and avoiding losing hazards (a notable exception being Russian pyramid in which both are legal shots).
In golf billiards, an area of the table (sometimes marked) that a player will be penalized for entering if their ball does not leave. Derives from the use of the term in the outdoor game of golf.

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 three-foul rule describes a situation in which a player is assessed a defined penalty after committing a third successive foul. The exact penalty, its prerequisites and whether it is in place at all, vary depending on the games. In nine-ball and straight pool, a player must be the told he is on two fouls in order to transgress the rule, and if violated, results in a loss of game for the former and a special point penalty of a loss of fifteen points (plus one for the foul itself) in the latter together with the ability to require the violator to rerack and rebreak. In Irish standard pool and English billiards, it is a loss of game if a player commits a third foul while shooting at the black. In snooker, three successive fouls from an unsnookered position result in forfeiting the frame. Repeat fouls from a snookered position are quite common - Dave Harold holds the record in a competitive match, missing the same shot 14 successive times.

The act of playing a devastating safety which leaves the opponent in a situation where it is very difficult or near impossible to make a legal hit on an object ball

This is English that turns into reverse English after contact with the object ball. This will close up the angle on a bank.

This playing to a number less than eight in a game of one pocket.

This is the white ball in carom games which is separated from the clear ball by a marking (usually a dot or spot).

Also shortstop, short-stop. This is a player that is excellent at pool, but tends to fall short of number one. A shortstop is the best player relative to a particular scene. A second-tier professional who is not (yet) ready for World Championship competition. It can also be applied by extension to a player who is one of the best in a region but not quite good enough to consistently beat serious road players and tournament pros. The term was borrowed from baseball.

Describing a shot which requires one or more balls to be played off several cushions, such as an elaborate escape or a positional shot; "he'll have to send the cue ball round the angles to get good position."

One of the two pockets one either side of a pool table halfway up the long rails. They are cut shallower than corner pockets because they have a 180 degree aperture, instead of 90 degrees. In the UK the term centre pocket or middle pocket are preferred.
