Did that senior English dan grade of Ki Aikido lure & lead Uke's attack before physical contact is made?? Or was Uke's attack static??
I believe luring & leading put effortless Aiki into the equation, while static attacks put merely Nage's Ki extension into the equation.
In my opinion, based in my understanding of Aiki & Ki extension, we need both for our Aikido to work.
Just my 2-cents worth..
It's 2 cents worth.....
Go up against someone who doesn't give a dam about whether you lead or lure.... or even do ukemi. Your technique (if you have any) will not be pretty as you imagine to be when and if it ever happens to you..... believe it.....
