This drill will introduce to what is known as Contact Throw. As stated in the lesson More about Throw, Contact Throw happens when the cue ball collides with the object ball. Note that Contact Throw is different from Spin or English Throw.
Ball placements:
Place the object ball about 2 1/2 diamonds from the bottom left corner pocket and about 1/2 diamond off the bottom long rail (as shown in the diagram). Next, place the cue ball 3 diamonds from the top right corner pocket and 1 1/2 diamonds from the top long rail (as shown in the diagram).
We will be doing this drill at different stroke speeds: soft, medium, and hard. Use only center ball hit on the cue ball (ie. no english should be applied on the cue ball).
First the soft speed shot; use center ball aim on the cue ball and aim the inside edge of the ferrule to the edge of the object ball. This should pocket the object ball.
Next is the medium speed shot; use center ball aim on the cue ball and aim the center of the cue tip to the edge of the object ball. This should pocket the object ball.
Next is the hard speed shot; use center ball aim on the cue ball and aim the outside of the ferrule to the edge of the object ball. This should pocket the object ball.
You will notice that there are slight adjustments in aiming with varying speeds. This is because of Contact Throw.
