Re: real world aikido
MMA is a sport. Aikido is a way of higher consciousness.
Real fighting should not adopt either of these strategies.
I train one way and apply aiki to it. I assume in my doctrine of battle that it will be a dark, cold, wet night where more than one person will attack me. They will likely have edged, blunt or percussive weapons in their hands.
All strategy must follow these assumptions. Tactics and techniques follow strategy. it cannot be the other way around or you will assume poorly about the hidden knife or gun. And In the U.S., this Gracie mano a mano stuff just doesn't cut it. In the U.S., you get ganged up on. There is no promise of a one-on-one fight.
