Re: Aikido in MMA and Street Fight
Real fight (ie. fights over something non-trivial): Pick up something heavy or sharp, use it. If anyone grabs your wrist or the heavy/sharp thing, to try and stop you from using "it", Aikido techniques offer many ways to escape the grab, make the attacker let go, or hurt their hand/wrist if they hold on. Once your weapon (hand) is free, go back to using your heavy/sharp thing.
Sparring: Sparring has structure. If that structure is boxing, then Aikido will not work well; Aikido isn't boxing. If that structure is wrestling, Aikido won't work well; Aikido isn't wrestling. If you know how to create the right sparring structure for Aikido, you will no longer need to ask this question.
