To be able to find what you need to know, you need to know how to look for it. All advanced grapplers test their technique and brainstorm for new ones. Most do it intuatively, but some have a systematic method. One method is from Grapplers Guide Jason Scully and I use it, because I am a member.
Just to outline the method it has nine steps:
1. Starting position
2. Goal (with very many sub-steps)
4. Own body - their body
6. Alive testing
I will try to use these subtitles in my future posts to learn the brainstorming process better and make it an automated way of working a problem in my Jits.
