Re: aikido vs jiu-jitsu
I would agree that the ultimate solution is to do that. I try to do it everytime I can. The problem is unless you can "out run" your opponent, or if you stand and fight, as in practice, that distance is taken away either by you or your opponent. Do it right with aikido principles and it works well. However the speed of a real fight does not allow for perfect technique and we end up on the ground more often than not. It is good to know what to do from there until you can regain control.
Aikido is a wonderful art, but as practiced by most, does not answer all questions of fighting with irmi and tenkan. Nor should it, as it is a DO art meant to convey principles of dynamic movement.
Be careful not to confuse aikido with real fighting!
