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.
The tip of your cue is the smallest but most important piece on all of the stick. Ranging between 12 mm and 14 mm depending on the taper of you shaft, the average and most common tip size is 13 mm. The tip is usually made from treated and compressed leather and is attached at the top of your cue by screw or glue to the ferrule. There are variances in cue tip resistance from soft to hard. The softer offering more chalk retention, and the harder offering more longevity and power transferred through your shot (the hardest, phenolic tips are often used on the break). Because the surface of the tip is beveled it offers you control on the spin and direction of the cue ball in your shot. To keep this control, it is important to scuff up the surface of your cue a little so as to enhance the chalk retention potential. In addition to keeping you tip chalked, you want avoid it mushrooming over the ends of the ferrule after too many impacts without refinement. To much use, and not enough care with proper tools can hinder your ability to master the control from your cue tip to your shot.
Feel generally refers to that elusive quality that makes one cue feel special or superior to another. In essence, it is the cumulative effect of all of a cues characteristics, including weight, shaft diameter, balance, grip material, length, etc. It can vary greatly from one player to another. A cue that feels great to one player does not necessarily fell good to another.
In snooker, the abandonment of a frame upon agreement between the players, so that the balls can be set up again and the frame restarted with no change to the score since the last completed frame. This is the result of situations, such as trading of containing safeties, where there is no foreseeable change to the pattern of shots being played, so the frame could go on indefinitely.
In pool, placing of the object balls back in the rack, after a foul break.

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).

When a ball goes into a pocket then pops back out. It really is not witchcraft, but is usually because the pocketed ball was traveling to fast and either ricocheted off the back or sides of the pocket opening. Sometimes,on tables with plastic inserts, the object ball can bounce out from the bottom of the pocket.
This is the final object ball you need to pocket in order to win a game of one pocket.
(Chiefly U.S.) Side spin (english) placed on a same side of the cue ball as the direction in which the object ball is being cut (left-hand english when cutting a ball to the left, and vice versa). In addition to affecting cue ball position, inside english can increase throw.
This is the apex ball in the triangle, racked on the foot spot in a normal game.
Also string off. Chiefly British; Obsolete: Same as string or lag.

When playing 9 Ball, a dead ball is an object ball the falls into a pocket when a foul has been committed (for example, the shooter scratches or does not hit the lowest ball first). If keeping score by counting balls fallen, neither player gets the point for that ball.
A soft joint-like plastic or linen base material. It lets the cue whip, putting more English on the cue ball.

This describes a shot in snooker where the cue contacts more than one object ball.
Also pro side of the pocket and missing on the professional (or pro) side of the pocket. Sometimes "of the pocket" is left off the phrase. To err on the side of overcutting a difficult corner pocket cut shot rather than undercutting in nine ball; "missing on the professional side of the pocket." So called because experienced players understand that on a thin cut, overcutting the object ball to a corner pocket will far more often leave the object ball in an unfavorable position for the incoming opponent than will an undercut, which often leaves the object ball sitting in front of or nearby the pocket it had been intended for on a miss. By contrast, in eight-ball, except when both players are shooting at the 8 ball, the incoming player after a miss is shooting for different object balls, so this maxim does not apply, and the opposite may be good strategy as, if the object ball stays near the pocket through an undercut, it is advantageously positioned for a subsequent turn and may block the opponent's use of the pocket.
This is a tip tool for cleaning the edges of you tip after mushrooming occurs.
Describes a player who needs only one more game win to be victorious in the match.
