Definition of Break and run

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".

A player skilled at very thin cut shots, and shots in which a ball must pass cleanly through a very narrow space (such as the cue ball between two of the opponent's object balls with barely enough room) to avoid a foul and/or to pocket a ball. Such shots may be referred to as "surgery", "surgical shots", "surgical cuts", etc. (chiefly US, colloquial). See also feather (US) or snick (UK).

This is a player who has the ability to make difficult shots in one pocket, because they are likely proficient at other pool games first.

This is a play where the shot of the cue ball is meant to end up in a certain place to loose your turn, but makes the next attempt difficult for your opponent. The shot is turned over, but will often times lead to a foul, giving you the ball back with a different view or ball in hand. This "safety" play is important if your shot isn't ideal, and you are likely to turn the ball over anyway.

See overcut.

This is to have control on the cue ball in your shots.

A defensive action taken when a player either has no "makeable" or "high percentage" shot or chooses to leave his opponent in a difficult situation. It is a legal shot and is not considered to be dirty pool. A safety must still conform with the rule concerning hitting the correct ball first and striking a rail afterwards. If a correct ball is accidentally pocketed while playing safe, the shooter must continue to shoot.

Also the hook. In snooker, a type of mechanical bridge that has only recently been endorsed by the WPBSA to allow its use in major tournament play. It is a normal rest with the head in line with the shaft, but the last foot or so of the shaft is curved. This allows players to position the curved end around an obstructing ball that would have otherwise left them hampered on the cue ball and in need of a spider or swan with extensions, which would have less control.

A pool cue designed for breaking. Along with sometimes having unusual weight or balance to build maximum speed for the cue ball, some break cues have stiffer shafts and special breaking cue tips to transfer energy more efficiently to the cue ball.

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.

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.

This is a tool that is used to shape a cue stick. It holds the cue in place while rotating it along a cutting edge. This tool can also be used to hold the cue in place while constructing or repairing other parts on the cue.

A shooter's body position and posture during a shot.

This is a shot where the cue ball contacts an object ball and moves it along a path, but because the cue ball is still in motion it re-contacts the object ball and pushes it in the pocket after it stops.

White talcum powder placed on a player's bridge hand to reduce moisture so that a cue's shaft can slide more easily. It is not provided in many establishments as many recreational players will use far more than is necessary and transfer it all over the table's surface. Venues that do provide it usually do so in the form of compress cones about 6-inches tall. Some serious players bring their own, in a bottle or a porous bag that can be patted on the bridge hand. Many players prefer a pool glove. Talc is frequently mistakenly referred to as "hand chalk", despite not being made of chalk.

A highly skilled hustler making money gambling while traveling. Fast Eddie Felson in The Hustler was a road player. One of the most notorious real-life road players is Keith McCready.

When the cue ball is tucked behind the corner of a pocket, therefore not allowing a direct shot at the object ball.

This is the ball that sits in the front, or apex, position in the rack.

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

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.

Same as back spin.

When the cue ball contacts three or more cushions in carom games.

Nine Ball is a rotation game so a player must hit the lowest numbered ball first.
The object of the game is pocket the 9-ball on any legal shot.
