Breaking OFF

The break takes place at the start of each frame, with the basic premise that the player breaking off must strike one of the red balls. A good break will the cue ball hitting a red  ball with minimum disruption to the pack of reds and then coming back up the table to rest as close to the baulk cushion as possible. This will then put pressuere on the opposing player.

Snookered

The cue-ball is said to be snookered when a direct stroke in a straight line to every ball on is wholly or partially obstructed by a ball or balls not on.

•  If one or more balls on can be struck at both extreme edges free of obstruction by any ball not on, the cue-ball is not snookered.
• If in-hand, the cue-ball is snookered if it is obstructed as described above from all possible positions on or within the lines of the "D".
• If the cue-ball is so obstructed from hitting a ball on by more than one ball not on the ball nearest to the cue-ball is considered to be the effective snookering ball, and should more than one obstructing ball be equidistant from the cue-ball, all such balls will be considered to be effective snookering balls.
• When Red is the ball on, if the cue-ball is obstructed from hitting different Reds by different balls not on, there is no effective snookering ball.
• The cue-ball cannot be snookered by a cushion. If the curved face of a cushion obstructs the cue-ball and is closer to the cue-ball than any obstructing ball not on, the cue-ball is not snookered.
