There are a lot of times when the two object balls are located in a half-table area. One of the more common shots is to play the cue ball in a half table circle. It comes off the first object ball, into the long rail, short rail, and opposite long rail and then connect with the second object ball.
This is a large selection of these types of shots. For each shot, there are two table layouts. The first is the ball positions on the table. The second is how the pro player made the point.
There are two ways you can use these examples. First - as a mental exercise. Study the ball layout and the ball paths to determine how the shot was played.
Second - as a table exercise. Set the balls up in the positions. Try to duplicate the shot. It may take only a few attempts, or a lot before you learn how to consistently score the point. You will do a lot of experimentation with different speeds and spins.
The result will be a better understanding on how to play similar shots during your competitions. Enjoy the learning process and good luck!!
