I understand the 2 body dynamics very well, but I can't see how the professionals apply their chalked cue and hit the way they do.
As a few for instances:
- How much does the chalk come into play in terms of friction?
- How off center is it possible to play?
- How do they aim the off center?
Also in a situation like this http://www.youtube.com/watch?v=McThDshEgU0 Ronnie O'Sullivan's fantastic play. What useful measurements are there to grade his skill?
