Aiming Technique #2
Another technique for aiming is by the use of your cue stick. Refer to the illustrations below. First, you need to determine the line of path of your object ball to the pocket (illustrated by the red arrow line in the illustration below) and point your cue stick in that direction.

- Measure the width of the object ball.
- Place the tip of your cue stick at 1/2 width from the object ball. This is your aim point.

The last thing you need to do is simply point your cue stick aim at the "aim" point and stroke. See illustration below.

Margin for Error
Depending on the size of the pocket opening (which varies between different types of tables), you normally have an allowed margin for error. Just remember that the closer the object ball is to the pocket, the larger is your margin for error and the farther away the object ball is from the pocket, the smaller your margin for error will be. However, it is always a good idea to strive for a perfect shot right in the middle of the pocket so you won't have to worry about your margin for error regardless of the size of the pocket opening.
