“Inside” and “outside” need a reference. A route around a group of balls is not the same thing as inside or outside side spin on a cut shot.
Name the reference
In common cut-shot terminology, inside side spin is on the side toward the cut; outside side spin is on the opposite side. Running and reverse spin refer instead to a particular cushion encounter. A named route therefore does not prescribe one spin setting for its entire journey.
Draw two candidates
This is our comparison worksheet, not a universal shot system. Label the cue ball C, first object ball A and final object ball B. Draw candidate 1 through the nearer corridor and candidate 2 around the farther corridor. For each, write the first event and every cushion before B. A shorter drawing is not automatically a legal or easier shot.
Check the moving obstruction
Follow A after the first collision, not just C. Mark where their paths cross and whether they could arrive together. Then compare the final approach to B: a route that clears A but approaches B through a narrow gap may be less usable. Neither distance nor a family name supplies a reliable success percentage.
Make a defensible choice
Save the same starting layout for both candidates. Keep table settings unchanged and vary one control at a time within each candidate; record clearance, cushion count and miss direction. In 3Ball these are model observations, not measurements of your stroke. Choose a physical-table reference only after testing it there. Do not translate this pair automatically into Korean 앞돌리기 and 옆돌리기: the diagram must establish the family.
