Why does the BAT emphasize only 3 types of cut shots?
A. Actually, this is not entirely true. Although the BAT does highlight the three main cut shots: 1/4, 1/2, 3/4, it will show variations of these cut shots by the fact that the player can see if the object ball is being cut more or less of these three standard cut shots. This is done by seeing the object through the BAT Window and also noting the degree and the contact point on the BAT Protractor. Once you are familiar with what constitutes a half ball cut, namely, a 30 degree angle and aiming directly at the edge of the object ball, then when you come across a shot that is slightly more or less of 30 degrees, you will know to aim slightly inside or outside of the edge of that ball. By making these three cut shots your reference points, it becomes easy to adjust accordingly when needed.
