A controversial opinion from Saul Goodman/Nobody Important/dlcox on Martial Talk:

Understanding how other, similar methods are used and deployed allows us to enhance our understanding of the strengths and weaknesses other methods and what we can do to improve ours.
Is chi sau a method of pummeling? If so then what is it developing and why?

Opinions welcome.
