I re-watched a couple of times and the communication between Chiba Sensei and Nour Sensei indeed seems a bit more complex than I had picked up on initially. Nour always looks like he is already toast as soon as he commits to a cut. That's very high level Aiki.
As I stated in my earlir blog its not always east to discernn what is going on in the encounter between Chiba Sensei /Juba Nour Sensei. As you said Nour Sensei ihas not much room to manouvre.Chiba Sensei is dictating the situation. .Cheers, Joe.
