The object-ball must be struck but ⅛ in order to carry the cue-ball to cushion at a and to give proper direction to the former ball.
The quick movement of the cue insures speed to the cue-ball.
In order to reach the point a with the cue-ball, which also gives direction to ball 1, it is absolutely necessary to strike very fine on the latter.
