Re: What technique would you apply to neutralize Brazilian Jujitsu attacker
The real problem is that you ask a question to which very few Aikidoka's can answer.
You will see the usual defensive answers like "why you wanna know? Aikido is..." or "when a BJJer will attack you?". But this is to hide the fact that someone who does only Aikido has not a clue on what to do on the ground. In dojo's it is never practiced and so no way to tell you.
One thing I agree with what I read, if a BBJer wants to take the fight to the ground in the long run it wil happen. So if you wanna know what to do the only thing is taking your Sensei and train in dojo with him on avoiding being taken down. But most likely go to a BJJ gym and learn some ground work which won't hurt you to know.
