Happoken no Kata

I published a post on my The School of Jan de Jong blog which uses the theory presented in my The Science Behind All Fighting Techniques to analyse the Happoken no Kata taught by Jan de Jong jujutsu, Yoseikan Budo, and Yoseikan Aikido.

The post is an example of the use of theory to gain understanding and insights into practice. It is also an example of the necessity to always question your teacher's instruction, but only when you understand the theory and the instruction does not stack up to the theory.
