Re: What technique would you apply to neutralize Brazilian Jujitsu attacker
I think the ultimate unstoppable technique that should have been used since the beginning of this thread is the Aikiweb Search Engine. Use words such as BJJ, shoot defense or any other BJJ specific terminology and you'lll find a host of very long threads dealing with almost everything to do with a BJJ/Aikido encounter.
For those of us here for some time, like Michael Fooks etc. this concept has been beaten to death, literally. Imho folks who compare style vs style instead of person vs person probably do not have very extensive experience/knowledge in fighting or sparring.
