The 3-6-9 System

You have two key lines from which you'll make adjustments: your strike-line and your corner-pin line.

Different players may have a different "line" but can still use this system, based off their own lines. The strike line will be different from the corner-pin line, too. For simplicity the diagrams here show the two starting lines (in yellow) using the 2nd or 3rd arrows.

To use the 3-6-9 you keep the same target and move your feet more to the left or the right. The lines drawn clearly show how moving more to the right results in the ball hitting pins left of your original line. Similarly, moving left with your feet makes your ball end up further to the right.
