If you decide to shoot the 15 ball with hard draw and don't compensate for object ball deflection the 15 ball will deflect and hit the long rail up a few inches away from the pocket as in the diagram below.
Diagram 2
If you adjust your aim about 1/8" or slightly more (depending on the amount of power you use) to the right on the 15 ball which would aim it to the short rail on the left of the pocket your shot will deflect dead into the pocket. In the diagram below the yellow represents the normal line of aim while the grey represents the adjusted aim.

Now when you shoot the ball hard without using english you don't have to miss.
*If you don't understand cue ball deflection read the lesson on "Predator Blues" then finish reading this lesson.
