Definition of Pool room

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.

The situation arising in many pool games where a ball is spotted to the table's foot spot or some other specific location and the cue ball must be shot from the kitchen or the "D". There are diamond system aiming techniques for pocketing such shots without scratching the cue ball into a pocket.

Three Ball is a pocket billiards folk game played with three standard pool object balls and a cue ball. The goal is to pocket the three object balls in as few shots as possible.

This is when a mistake is made in the shot and the resulting contact between balls forces you to miss the shot.

Chiefly British: The cushion on the top rail. Compare foot cushion; contrast bottom cushion.

A shot where the cue ball must hit the object ball so as to make it travel out of a straight line, at a different angle, toward its destination.

The heavy, finely milled rock (slate) that forms the bed of the table, beneath the cloth. Major slate suppliers for the billiards industry are Italy, Brazil and China. Some cheaper tables, and novelty tables designed for outdoor use, do not use genuine slate beds, but artificial materials such as Slatrol.

A British term for someone with little experience or understanding of the game, who may be skilled at potting individual balls but does not consider tactics such as position or safety; "he's a potter not a player." See also banger.

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.

Describing a pot played at such a pace as to just reach the pocket and drop in without hitting the back.

This is to execute a shot where the cue ball is controlled perfectly and stops where you want it to exactly.

Also highs, high balls, high ones. In eight-ball and related games, to be shooting the striped suit (group) of balls (9 through 15); "you're high balls" or "I've got the highs" ("you're high" is rare, because of the "intoxication" ambiguity). Compare stripes, yellows, big ones, overs; contrast low.

This is missing the fact that you owe a ball in a game of one pocket after a scratch.

A pejorative term for an improper rack in which the balls are not properly in contact with their neighbors, often resulting in a poor spread on the break.

To intentionally lose a game, e.g. to disguise one's actual playing ability. An extreme form of sandbagging. See also hustle. See also Match fixing for the synonym "tank", used in sports more generally.

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.

This refers to a shot that is not banked, does not hit a rail and goes into the pocket without contacting any other balls on the table.

This shot refers to using heavy follow to push through an object ball on its way to its destination.

Descriptive of any game in which the object balls must be struck in numerical order. Billiard researcher Mike Shamos observes that it would be more intuitive to call such games "'series' or 'sequence'". The term actually derives from the set-up of the game Chicago, in which the balls are not racked, but placed numerically around the table along the cushions (and must to be shot in ascending order). Other common rotation games include pool (obviously), nine-ball, seven-ball, ten-ball.

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.

Also known as a Dead cushion. A cushion that has either lost a degree of elastic resiliency or is not firmly bolted to the frame, in both cases causing balls to rebound with less energy than is normal.

A common aiming method in which a phantom ball is imagined frozen to the object ball at the point where an imaginary line drawn between their centers is aimed at the desired target; the cue ball may then be shot at the center of the "ghost" ball and, ideally, impact the object ball at the proper aiming contact point. The ghost ball method of aiming results in misses where adjustment is not made for collision induced throw.

See overcut.

Also split shot. In pool, a type of shot in which two object balls are initially contacted by the cue ball simultaneously or so close to simultaneously as for the difference to be indistinguishable to the eye. In most sets of rules it is a foul if the split is one in which one of the object balls is a (or the only) legal target (ball-on) and the other is not; however, such a split is commonly considered a legal shot in informal bar pool in many areas if it is called as a split and does appear to strike the balls simultaneously).
