Re: Aikido does not work at all in a fight.
Following up I suggest you either Google Ueshiba Sensei or go to You-Tube to watch some excellent footage of his seamless and quite powerful techniques. If Rickson Gracie is aware of these films he should realize that BJJ would have little effect on forceful Aikido. The videos unmistakably demonstrate the proactive side of Aikido. Sensei Ueshiba moves to and disables opponents. He doesn't just wait around for an attack. Watch and marvel.
