In three-cushion billiards, we have the same kiss. But, since we are not trying to bank the red ball into a pocket, we have more choices of how to avoid the kiss. The diagram shows that situation. You will have to use your judgment to determine if you can get to the side rail or not. It is fairly easy to prove that the kiss zone will be wedge shaped, as the angles are what are important here.
Distances are relatively unimportant.
It is also easy to show that the wedge goes near a line between the pocket and the object ball. It is more difficult to find the exact edges of the wedge. A person should probably experiment to become comfortable with all this.
