24 Random Essential Billiards Terms

A rule in blackball whereby after an opponent has faulted and thus yielded two shots, if the incoming shooter pots a ball on the first shot, (s)he is still allowed to miss in a later shot and take a second shot in-hand (from the "D" or from baulk, or if the opponent potted the cue ball, from anywhere)—even on the black, in most variants. Also called the "two visits" rule; i.e., the two penalty shots are considered independent visits to the table, and the limiting variants discussed at two shots below cannot logically apply.
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.
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'.
To indicate where something is to be done. To "mark the pocket" means to indicate which pocket you intend to sink an object ball.

The placement of the balls, especially the cue ball, relative to the next planned shot. Also known as shape.
To intentionally rebound the cue ball off both of the pocket points to achieve position.
Also nurse shot, nursery shot. In carom games such as straight rail, balkline and cushion caroms, where all the balls are kept near each other and a cushion, and with very soft shots, can be "nursed" down a rail on multiple successful shots that effectively replicate the same ball setup so that the nurse shot can be repeated again (and again, etc.). Excessive use of nurse shots by players skilled enough to set them up and pull them off repeatedly at will is what led to the development of the balkline carom billiards game variations, and repetitive shot limitation rules in English billiards. A clear example of why: In 1907, Tom Reece scored a record break of 499,135 consecutive points over a period of five weeks, without a miss, using the cradle cannon nurse shot.
