Re: Aikido does not work at all in a fight.
I'm only a sixth kyu, so take my opinion for what its worth. That said, from reading and watching others, it seems that technique is less important than reading your opponent. If you know what your opponent is doing and going to do, the response, regardless of the technique, will work, as long as your opponent does not counter-read you or is not significantly more skilled. I would think this applies to any martial art, but Aikido certainly spends a great deal of time on blending with the opponent. While I've not studied bjj or any mma styles, if they spend time on the same thing, they would also be effective. Which one is better? Who cares. The goal is always to neutralize aggression, whether it be redirecting the energy harmlessly (for both attacker and attackee) or beating the crap out of the other guy. It really seems to be a question of personal belief. I appreciate all of the different viewpoints; its what makes this forum so informative!
