What is it?
Running Side is a term used to describe the following:
- Side that WIDENS the throw off a ball.
- Side that RUNS the ball off a cushion i.e. accelerates the ball and narrows the angle with the cushion.
If you hit a ball before a cushion (or vice versa) the term becomes confusing as you can 'run' off a ball then 'check' off a cushion! In this case, use the FIRST point of contact to describe the shot. e.g. If you run off a ball and check off a cushion - this would be called running side.
However, it becomes confusing at very thin contacts with the object ball. If in doubt describe what you are referring to e.g. running off the object ball to check off the cushion.
