Freeze the two balls at diamond no. 7 as shown.
Position the cue ball so that you are shooting between diamonds
no. 7 and 8. Hit the ball with top left using a moderate stroke.
Aim the 3 ball in the direction of the dotted arrow.
If the 3 ball kisses across the table toward
diamond no. 1, hit less ball. If it kisses toward diamond no. 8,
hit more ball.
