Definition of In turn

"Pocket billiards," or a game in which balls are shot into pockets.

Skilled playing in which knowledge of ball speed, angles, post-impact trajectory, and other factors are used to gain position (i.e. a good leave) after the target ball is struck. The goals of position play are generally to ensure that the next shot is easy or at least makeable, and/or to play a safety in the advent of a miss (intentional or otherwise).

A rack in the form of an equilateral triangle. There are different sizes of triangles for racking different games (which use different ball sizes and numbers of balls), including the fifteen ball racks for snooker and various pool games such as eight-ball and blackball. A larger triangle is used for the twenty-one ball rack for baseball pocket billiards). The smallest triangle rack is employed in three-ball (see illustration at that article) but is not strictly necessary, as the front of a larger rack can be used, or the balls can be arranged by hand.
The object balls in triangular formation, before the break shot, after being racked. See also pyramid.

A form of nurse shot in English billiards, in which the red ball, which must be spotted to a specific location after every time it is potted before another shot is taken, is potted in such as way as to leave the cue ball in position to repeat the same shot, permitting a skilled player to rack up many points in a single break (series of shots in one visit).

A British term for a pot that requires very fine contact between cue ball and object ball. See also feather.

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.

Slang term for the cue ball.

A chiefly British term for a set of mechanical bridges. British-style rests differ from most American-style rake bridges in shape, and take several forms: the cross, the spider and the swan (or goose neck), as well as the rarer and often unsanctioned hook. When used unqualified, the word usually refers to the cross. Rests are used in snooker, English billiards, and blackball.
