Re: aikido vs jiu-jitsu
Just to make things a little more messy...
As I understand it, jiu-jitsu (among other things, I'm sure) tends to emphasize grappling with a single attacker. Aikido tends (among other things) to emphasize movement among multiple attackers. I think it's reasonably clear that pure aikido training does not prepare one for well for grappling. My question is:
What would the jiu-jitsu response be to three or four attackers?
