Cue-ball ⅝ left, object-ball ⅝ left; stroke, “ordinary.”
If the cue is delivered below the centre of the cue-ball, with the object-ball 1 touching the cushion, the cue-ball will rebound at an acute angle that generally fails to effect the carom. The objective point is the cushion at b, which insures the stroke, and if the angle be always calculated from a point on the second cushion with the cue-ball so delivered as to reach that spot, the remainder of the stroke is assured and will take care of itself. That is to say, draw the angle required from the object-ball to the first cushion, then from that point to the second cushion.

Illustrating a peculiar two-cushion stroke with the application of twist and draw.
Cue-ball ¼ left, ⅝ below, object-ball ½ right; stroke, “medium.”
The purpose in striking cue-ball ⅝ below is to reach cushion at a by making no more than ½ on object-ball, driving it to c. The ¼ left is given the cue-ball that it may perform the angle a to b, which accomplishes the carom. Greater twist would perform a more obtuse angle to side cushion, striking at e.
