Double-Baulk - English Billiards
Double Baulk Describes the position where both the red and the non-striker's cue-ball are behind the baulk-line, and the striker is 'In-Hand'. When playing from this position, the striker must cause the cue-ball to contact a cushion that is out of the baulk area before it makes contact with either object-ball.
See:-  Baulk · Baulk-Line · In-Hand · Line-Ball

Describes the cue-ball striking the same object-ball twice, and the reaction caused by the cue-ball striking an object-ball that is close to or touching a cushion, and then being forced away when the object-ball rebounds from the cushion.
Dump Shot See:-  Kiss

A stroke in which the cue-ball is struck sharply below centre, with little or no follow-through of the cue. This causes the cue-ball to slide, or skid through the early part of its run. Friction on the cloth gradually slows the cue-ball until the drag effect is diminished enough to let it roll naturally. Side, if used with drag, does not begin to function until the cue-ball has lost the drag effect.
See:-  Back-Spin · Screw · Stun

Dump Shot - Snooker
A safety stroke played when there is no easy way to return the cue-ball to the baulk area. Usually played with a fairly thick contact on the object-ball to send that towards baulk, while the cue-ball comes to rest close to the top cushion.
See:-  Attacking Safety · Containing Safety · Safety

English Billiards
The correct name given to the form of Billiards as it is played in the UK. Three balls are used:- one plain white, one spot white (or yellow), and one red. The three methods of scoring are:-

   A Cannon:-
   by causing the cue-ball to contact both object-balls, value - 2 points.

   A Losing Hazard:-
   by going 'In-Off' either object-ball, value - white (or yellow) 2 points, red 3 points.

   A Winning Hazard:-
   by potting either object-ball, value - white (or yellow) 2 points, red 3 points.

To start the game the red is placed on the 'Spot' and the first player must play his cue-ball at it from the 'D'. His opponent's cue-ball is not on the table until his first visit, when he too must play from the 'D'. The winner is the first player to reach a predetermined number of points, or the player with the highest score at the end of a specified period of time.
The full rules can be found on the website of the World Snooker Association.
