24 Random Essential Billiards Terms

The profile of the shaft of the cue as it as it increases in diameter from the tip to the joint. A "fast" or "slow" taper refers to how quickly the diameter increases. A "pro" taper describes a shaft that tapers rapidly from the joint size to the tip size so as to provide a long, untapered stroking area.
Linen made from flax and produced in Ireland which is often used to wrap the gripping area of the butt of a cue.
Also pro side of the pocket and missing on the professional (or pro) side of the pocket. Sometimes "of the pocket" is left off the phrase. To err on the side of overcutting a difficult corner pocket cut shot rather than undercutting in nine ball; "missing on the professional side of the pocket." So called because experienced players understand that on a thin cut, overcutting the object ball to a corner pocket will far more often leave the object ball in an unfavorable position for the incoming opponent than will an undercut, which often leaves the object ball sitting in front of or nearby the pocket it had been intended for on a miss. By contrast, in eight-ball, except when both players are shooting at the 8 ball, the incoming player after a miss is shooting for different object balls, so this maxim does not apply, and the opposite may be good strategy as, if the object ball stays near the pocket through an undercut, it is advantageously positioned for a subsequent turn and may block the opponent's use of the pocket.
This is to miss your shot but either luckily or on purpose leave your opponent with nothing to shoot at.
A slang term for a cue, usually used with "piece", as in "that's a nice piece of wood".
This is the final object ball you need to pocket in order to win a game of one pocket.
A game that basically cannot be lost based on disparity of skill levels; "this game is a lock for him."
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 first shot in a game - aimed at a set of racked balls.
To execute the first shot in a new game.
In snooker this term can be use to indicate a series of successive shots completed by a single player.
This is the imaginary line that a ball would need to follow in order for it to result in an effective bank shot.
When a player is playing flawlessly, just "cannot miss" and the game seems effortless.
This can be a shot where the best option for you is to sink a ball in you opponents pocket in the game of one pocket. This can also refer to the act of offering an opponent a ball adjustment to even the playing field.
The World Confederation of Billiard Sports (WCBS, sometimes called the World Confederation of Billiards Sports) is the international umbrella organization encompassing the major cue sports (billiards-type games), including carom billiards, pool games of several varieties, and snooker. The primary aim of WCBS is to establish billiard-type sports as medal events in as many multiple-sports competitions as possible, on both regional and world levels. The ultimate goal of WCBS is to have billiard sports included in the Olympic Games.
A cluster of balls. In snooker, the bunch of reds that are typically left below the pink spot in the early stages of a frame, not including those reds that have been released into pottable positions.
This is a shot where the cue ball follows directly behind the sunk object ball into the pocket right after it falls.
This describes a shot where you bank the object ball off of a rail and then sink it in a corner pocket.
Also last pocket. A common rule in informal bar pool, especially bar/pub eight-ball, in which the money ball must be pocketed (potted) in the same pocket as the shooter's last object ball (each player may be said to eventually "own" a pocket, for the duration of the game, in which their 8 ball shot must be played if they have already run out their suit). The variant is not extremely common in the United States or the UK, but is near-universal in much of Latin America (where two cue ball scratches are permitted when attempting the 8 ball shot and count as simple fouls, with only a third scratch constituting a loss of game). Last pocket is also common in North Africa. Last-pocket rules require careful position play, and frequently result in bank and kick shots at the 8 ball.
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.
Sometimes called a snake shot. A carom billiards shot, common in three-cushion billiards, where the cue ball is shot with reverse english at a relatively shallow angle down the rail, and spins backwards off the adjacent rail back into the first rail.
Sometimes interchangeable with scratch, though the latter is often used only to refer to the foul of pocketing the cue ball. A violation of a particular game's rules for which a set penalty is imposed.
Same as back spin.
"Pocket billiards," or a game in which balls are shot into pockets.
When a player is on the receiving end of a devastating safety where it is very difficult or near impossible to make a legal hit on an object ball.
When the object ball lies behind another ball which makes it impossible to be struck by the cue with a direct hit.
