Also shake bottle, pea bottle, pill bottle, kelly bottle, tally bottle. The bottle used in various games to hold numbered peas, it is employed to assign random spots to players in a roster (such as in a tournament), or to assign random balls to players of a game.
Either of the balls on the lateral extremities of a racked set of balls in position for a break shot; the two balls at the outside of a 15-ball rack in the back row, or the balls to the left and right of the 9 ball in nine-ball's diamond rack-shaped opening set up position. In nine-ball It is seen as a reliable sign of a good break (which is normally taken from close to either cushion in the kitchen) if the opposite wing ball is pocketed.
The triangular device, generally plastic, used to group the balls in a pyramid form prior to the beginning of a game.
The imaginary line drawn perpendicular to the impact line between the cue ball and an object ball. The cue ball will travel along this line after impact with an object ball if it has no vertical spin on it (is sliding) at the moment of impact on a non-center-to-center collision. See also stun shot.
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.
Also known as a "Dirty Defense" or "Dirty Foul". 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.
In blackball, a penalty conceded by a player after a fault. The incoming opponent is then allowed to miss twice before the faulting player is allowed another visit. Many local rules state the in-hand from the "D" or baulk (or if the opponent potted the cue ball, from anywhere) nature of the second shot is lost if a ball is potted on the first shot, that it is lost if the ball potted in the first shot was that player's last coloured ball (object ball in their group), and/or that there is only ever one shot on the black after a fault.
An imaginary line dividing the table into two equal halves lengthwise. It intersects the head string, center string and foot string at the head spot, center spot and foot spot, respectively.
Pocket openings that are significantly wider than are typical and thus allow shots hit with a poor degree of accuracy to be made that would not be pocketed on a table with more exacting pocket dimensions.
This is a table that offers poor conditions for play; it is either dirty, wet, or overall poor quality.
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.
Describes lucky or unlucky "rolls" of the cue ball; "I had good rolls all night; "that was a bad roll." However, when said without an adjective ascribing good or bad characteristics to it, "roll" usually refers to a positive outcome such as in "he got a roll".
The roll: same as the lag.
When two or more object balls are frozen or nearly frozen, such that cue-ball contact with one object ball, without the necessity of great accuracy, will almost certainly pocket an intended object ball in the cluster. The most common form of dead arrangements are the dead combination or dead combo (a combination shot in which contact with the first object ball will pocket another one), and the dead kiss, in which contact with the first object ball will pocket it off of another one. See also wired.
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.
In snooker, a shot where a player fouls by missing the ball on altogether. The miss rule allows for his opponent to have the player play exactly the same shot again, or at least as accurately as the referee is able to reproduce the ball positions. A miss usually occurs when a player makes an unsuccessful attempt at escaping from a snooker. It is a controversial rule aimed at formally discouraging deliberate fouls. In professional snooker, a referee will almost always call a miss on any foul where the player misses the ball on altogether, regardless of how close the player comes to hitting it, however no miss can be called when either of the players requires snookers to win the frame. If a player is called for a miss three times in a single visit while not snookered, he forfeits the frame; to avoid this, players almost always play an easy hit on their third attempt, even if it is likely to leave a chance for the opponent.
Same as spot
A shot in which if the target is missed, the opponent is safe or will not have a desirable shot;
A shot in which there are two ways to score;
A shot in which a second ball is targeted to be pocketed, broken out of a cluster, repositioned or some other secondary goal is also intended.
The act of setting up the balls for a break shot. In tournament play this will be done by the referee, but in lower-level play, players either rack for themselves or for each other depending on convention.
To play a shot with the stroke and speed that makes it easiest to pocket the object ball, even at the expense of sacrificing position.
A game of pool played on a table shaped like a rectangle, with or without pockets.
Also topspin, top-spin, top. Same as follow. Contrast bottom spin, back spin.
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."
Side spin on the cue ball that causes it to unnaturally roll off a cushion (contacted at an angle) against rather than with the ball's momentum and direction of travel. If angling into a cushion that is on the right, then reverse english would be right english, and vice versa. The angle of deflection will be steeper (narrower) than if no english were applied. The opposite of running english, which has effects other than simply the opposites of those of reverse english.
A Baulk line is line drawn across the table 29 inches from the bottom cushion and parallel to that cushion.
