Re: techniquies in street fights
I was wandering through a side alley on my way to the ATM during the middle of the day in a far northern NSW (Oz) town called Lismore a couple of months back. Not quite sure what was going on, but one guy hassling another in front of crowd of people seated outside a cafe - the receiver looking more like a street drunk than not. After much provoking, the reciever finally took a swing at the provoker in pretty much a perfect Yokomen strike, complete with some sort of glass bottle in hand. I'll leave the rest to your imagination, suffice to say that the provoker then proved that he was one of those people that should never have received martial arts training in the first place.
The basic point is that the attacks used in Aikido are reflected in what one could expect in the real world.
