Definition of Single elimination

Any ball that may be legally struck by the cue ball.

Balls remain unmoved after a player's shot.

To "give someone weight" is to give them a handicap so the game is more even in skill level. If one player is significantly better than the other in a game, then you can add some weight, more or less balls for someone, to even the difficulty load between each player.

Inadvertent english placed on the cueball by a failure to hit it dead center on its horizontal axis. It is both a common source of missed shots and commonly overlooked when attempts are made to determine the reason for a miss. In UK parlance this is usually called 'unwanted side'.

In snooker, a phrase used to describe a situation where the player has an easy pot and in general the balls are in a position to go on to make a sizeable break.

In eight-ball and related games, describes the situation in which neither player has yet claimed a suit (group) of balls. Often shortened to simply open: "Is it still an open table?" "Yes, it's open."

Also spot-stroke, spot hazard. 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).

Nearly table-length distance between the cue ball and target object ball, or near cue and object balls and target pocket, i.e. a potentially difficult shot ("you sure left me a lot of green on that one").
The cloth covering the table.

This is a term to describe 100 break points in a game of snooker.

Also lady's aid or girly stick. A denigrating term for the mechanical bridge.

An imaginary line running horizontally across a billiards table from the second diamond (from the foot end of the table) on one long rail to the corresponding second diamond on the other long rail. The foot string intersects the long string at the foot spot. It is rarely drawn on the table.

In snooker, a pot into any of the corner pockets where the cue ball had started in the opposite lengthwise half of the table. In other words, a pot in which the cue ball or object ball crosses an imaginary line joining the middle pockets.

A joint type in which the butt and shaft screw together in a tight lock, resulting in a better shot with more hitting power.

A gentle tap of the cue ball with the intention of getting it as tight as possible behind another ball, in the hope of a snooker. It is most common in the game of snooker, and is illegal in many pool games, in which on every shot a ball must either be pocketed, or some ball must contact a cushion after the cue ball has contacted an object ball.

Same as solids, in New Zealand. Compare little, small, reds, low, spots, dots; contrast overs.

The United States Snooker Association (USSA) is the internationally recognized governing body of the sport of snooker in the United States.

Certain rules say you must designate your shot before taking it. Generally this is just calling the ball to be sunk in which pocket, and is not dependent on touching rails or other balls, but very well can be.

An abrasive tip tool used as a grinder to roughen the cue tip to better hold chalk after it has become hardened and smooth from repeated impacts with the cue ball. Tappers serve the same purpose, but are used differently. Similar to a shaper, but shallower and less rough.

A small clamping tip tool used to firmly hold and apply pressure to a replacement cue tip until the glue holding the tip to the ferrule has fully dried.

Also piquet. Either a massé shot with no english, or a shot in which the cue stick is steeply angled, but not held quite as vertical as it is in full massé.

Hitting the object ball with not enough of a cut angle; hitting the object ball too full or "fat". It is a well-known maxim that overcutting is preferable to undercutting. See also professional side of the pocket.
