Definition of anchor nurse

A type of nurse used in carom billiards games. With one object ball frozen to a cushion and the second object ball just slightly away from the rail, the cue ball is gently rebounded across the face of both balls, freezing the away ball to the rail and moving the frozen ball away the same distance its partner was previously, resulting in an identical but reversed configuration, in position to be struck again by the cue ball from the opposite side.

24 Random Essential Billiards Terms

A three cushion billiards shot in which the cue ball first strikes two cushions before hitting the first object ball then hits a third cushion before hitting the second object ball. So called because the shot opens up like an umbrella after hitting the third rail. Umbrella shots may be classified as inside or outside depending on which side of the first object ball the cue ball contacts.
This shot is a minimally calculated distressed shot which makes it evident to the opponent you no longer have any hope to winning the game.
This is to step up to the table and successfully execute a difficult shot.
This is missing the fact that you owe a ball in a game of one pocket after a scratch.
An imaginary line dividing the table into two equal halves lengthwise. It intersects the head string, center string and foot string at the head spot, center spot and foot spot, respectively.
A cue dedicated to jumping balls; usually shorter and lighter than a playing cue and having a wider, hard tip. Also referred to as a jump stick.
Two or more object balls that are touching or are close together.
The ACS Canadian affiliate organization, the Canadian Cue Sport Association.
You can cheat the pocket by angling your shot to go in at the right or left of the pocket opening when sinking a shot. This permits the cue ball to strike the object ball at a different contact point than the most obvious one.
Five-pin billiards is a today usually a carom but sometimes still a pocket form of cue sport, popular especially in Italy and Argentina but also in some other parts of Latin America and Europe, with international, televised professional tournaments. The game is sometimes referred to as Italian five-pins or Italian billiards.
When an opponent either purposely successfully executes a defensive shot or misses their shot resulting in a bad leave for the next player.
Example: "I was left bad every time he missed his shot".
The effect of shooting regulation-weight object balls with an old-fashioned over-weight bar table cue ball, such that the cue ball moves forward to occupy (sometimes only temporarily), or go beyond, the original position of the object ball, even on a draw or stop shot, because the mass of the cue ball exceeds that of the object ball. Players who understand smash-through well can use it intentionally for position play, such as to nudge other object balls nearby the target ball. Smash-through also makes it dangerous in bar pool (when equipped with such a cue ball) to pocket straight-on ducks with a stop shot instead of by cheating the pocket because of the likelihood of scratching the cue ball.
A Carom game with lines drawn to form rectangles that restrict play and reduce the potential for high runs.
Australian: Defeated with all seven of one's object balls (in blackball or eight-ball) remaining on the table.
To take one's two-piece cue stick apart. When done before a game's conclusion, it often indicates that the game is conceded.

1- Pocketing of the cue ball in pocket billiards. In most games, a scratch is a type of foul. "Scratch" is sometimes used to refer to all types of fouls.

2- British term/slang for Draw

A shot that only a novice or fool would take. Usually because it is a guaranteed scratch or other foul, or because it has a low percentage of being pocketed and is likely to leave the opponent in good position.
In blackball, a situation where the player cannot see any of the balls she/he wants to hit due to obstruction by other balls or the knuckle of a pocket. The player must call "total snooker" to the referee, which allows a dispensation to the player from having to hit a cushion after contacting the object ball, which is otherwise a foul.
A highly abrasive tip tool used to shape an unreasonably flat new cue tip, or misshapen old one, into a more usable, consistently curved profile, most commonly the curvature of a nickel or dime (or equivalently sized non-US/Canadian coin) for larger and smaller pool tips, respectively. Similar to a scuffer, but deeper and rougher.
A players skill level, ball advantage or match advantage when using a handicapping system.
The overall competition between two players, two pairs of players or two teams of players, usually consisting of a predetermined number of frames or games (sometimes organized into rounds).
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.
Named after Chicagoan J. E. Parker, it is a 3½ × 7 inch box drawn on a balkline table from the termination of a balkline with the cushion, thus defining a restricted space in which only a set number of points may be scored before one ball must be driven from the area. Now supplanted by anchor spaces, it was developed to curtail the effectiveness of the anchor nurse, which in turn had been invented to exploit a loophole in balkline rules: so long as both object balls straddled a balkline, there was no restriction on counts, as each ball lay in a separate balk space.
Similar to run out, but more specific to making all required shots from the start of a rack. Also known as also break and run or break and dish.
