Definition of Road player

This refers to how a player is playing on a particular occasion (a player's skill level). If their game is good, then they are at a high speed, but if they are not playing up to their potential, then they are playing at a lower speed.

When complete focus allows you to execute quality billiards play with simplicity and seeming ease.

To maneuver a ball on a shot so that it will be favorably positioned for later play into a particular pocket, even at the expense of sacrificing position or the inning to achieve that result.

A deliberate foul that leaves the balls in a safe position, reducing the risk of giving a frame-winning chance to the opponent. The miss rule in snooker was implemented primarily to discourage the professional fouls.

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

This is a very easy and safe shot to execute in the game of one pocket.

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 on the lemon. Disguising the level of one's ability to play.

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.

When the object ball banked of a rail goes directly in a pocket without kissing or touching any other object balls.

A break shot in which the rack (pack) is disturbed as little as possible within the bounds of a legal shot, in order to force the opponent to have to break it up further. A soft break is desirable in some games, such as straight pool, in which breaking is a disadvantage; and forbidden by the open break rules of other games such as nine-ball and eight-ball.

Describing a shot which requires one or more balls to be played off several cushions, such as an elaborate escape or a positional shot; "he'll have to send the cue ball round the angles to get good position."

In a tournament, to place high enough to receive a payout. E.g., in a tournament that pays from 1st down to 5th places, to be at least 5th place is to be in the money.

A shot aimed so that the center of the cue ball is in line with the edge of the object ball, eclipsing half of the ball. "Hit it just a little thinner than half-ball." Assuming a cling does not occur, the shot will impart post-contact momentum on the object ball in a direction 30° (which is arcsin(1 - x), where x is the fraction of object ball eclipsed: ½ in this case) off the direction of the cue-ball's pre-contact momentum. Also notable because the carom angle the cue ball takes is more consistent than at other contact points.

This is a version of double elimination tournament play that splits the field of competitors into two brackets that come together for a single elimination championship game.

In snooker, the highest-value colour ball on the table, being worth seven points. In some (especially American) snooker ball sets it is numbered "7" on its surface.
The black ball (usually numbered "8") in the eight-ball variant game blackball (and its variants); also the common British term for the slightly larger but otherwise identical 8 ball in a kelly pool set (a.k.a. American or WPA pool set).

Three Cushion is a form of carom billiards.
The object of the game is to carom the cue ball off both object balls and contact the rail cushions at least 3 times before the last object ball. A point is scored for each successful carom.

A set of paired balls in the game of cribbage pool that have a number value which combined equal 15. For example, the 8 ball and the 7 ball added together equal 15 and thus constitute one cribbage if pocketed in succession.

This is what is brought to the table if you are playing at your best potential.

Principally British: In snooker, if a player wins a match without the need for the final session to be played (for example, if a player wins a best-of-25-frames match split into three sessions - two sessions of eight frames and one of nine - by a margin of say, 13 frames to 3), then they are said to have won the match "with a session to spare".

Describes the propensity of a player losing small sums of money at gambling to suddenly sharply increase the stakes; often continuing to lose until broke. Compare Chasing one's money.

This describes balls that are not able to be made in a pocket, either because they are high up on the table, in a different pocket, or in a cluster that makes the shot difficult. This condition of being out of play obviously exists on different difficulty levels.

Also dead ball shot. A shot intended to slow down or "kill" the cue ball's speed as much as possible after contact with an object ball; usually a shot with draw, often combined with inside english. It is often shortened to kill.

Chiefly British: Same as shark (senses 1, 2). The term appears in lyrics from The Mikado (1884) in relation to billiards, and developed from sharper (in use by at least 1681, but now obsolete) meaning "hustler" but not specific to billiards.
