Definition of Ibsf

A shot in which the cue ball is driven first to one or more rails, then hits an object ball and kisses back to the last rail contacted. It is a common shot in carom games, but can be applied to such an instance in any relevant cue sport.

These are fouls made in one turn and then on the next by the same player each time. Some games have a rule that a player will lose the rack or match with three succesive fouls.

To fail to make a legal shot.

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.

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.

Also in the zone. Describes an extended period of functioning in dead stroke ("She's in the zone").

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.

On a shot, the extension of the cue stick through the cue ball position during the end of a player's stroke in the direction originally aimed.

When the object balls in straight rail pool are lined up close to each other, but extending out from the cushion, and you choose to bounce off the first object ball at the cushion and then come back to graze the second object ball. This technique can be used to continue scoring points as long as you are efficient with the shot.

In three cushion billiards, the most standard shot where the third ball is advantageously placed in a corner.

The desired angle that must be created between the path of the cue ball and the path of the object ball upon contact to pot the object ball. It is usually measured to the center of the pocket. See also aiming line.

In snooker, the abandonment of a frame upon agreement between the players, so that the balls can be set up again and the frame restarted with no change to the score since the last completed frame. This is the result of situations, such as trading of containing safeties, where there is no foreseeable change to the pattern of shots being played, so the frame could go on indefinitely.
In pool, placing of the object balls back in the rack, after a foul break.

A shot in which the cue ball is potted after caroming off another ball. In snooker and most pool games doing this would be a fault (foul), but the move will score points in many games in which hazards (as such) apply, such as English billiards, or in the final or game point in Cowboy pool. The term derives from this hazard costing the player points in early forms of billiards.

This is a simple method of gambling where bets are determined between each game instead of playing matches.

1- Shortened phrase of "ball-in-hand".

2 - In snooker, the ability to place the cue ball anywhere inside the boundaries of the D. This occurs at the start of a frame, and after the cue ball has been potted or forced off the table.
Also a short form of "Ball In Hand".

The number of balls pocketed in an inning in pool (e.g., a run of five balls), or points scored in a row in carom billiards (e.g., a run of five points). Compare British break (sense 2), which is applied to pool as well as snooker in British English.

Any shot in which the cue ball or an object ball has to squeeze by (just miss with almost no margin for error) another ball or balls in order to reach its intended target.

When the cue ball contacts three or more cushions in carom games.

The normal phenomenon where the object ball is pushed in a direction very slightly off the pure contact angle between the two balls. Caused by the friction imparted by the first ball sliding past or rotating against the other ball.

This word is used as slang to define a player as amateur or recreational.

This game is played on a smaller octagonal table filled with bumpers in the middle and two more bumpers surrounding a hole on each side of the table. The game is played by trying to sink the balls into the opposite pocket by hitting the object ball directly instead of using a cue ball.

In snooker, any of the three colour balls that get spotted on the baulk line: the yellow, green or brown ball.

Anything that causes a foul according to the rules of a game.

Also bar box, pub table, tavern table. Distinctive pool tables found in bars/pubs/taverns, and often in various other venues such as family entertainment centers and arcade rooms at bowling alleys. They are almost always coin-operated and smaller than tables found in pool halls. Typical bar boxes are 3.5 ft (1.1 m) × 7 ft (2.1 m).
