Re: Escape from ikkyo ??
Sorry, read it a bit more clearly. The zig zag, and the downward trajectory is probably needing some refinement that I cannot picture. If they are being projected away and forward, then the roll is easier.
I am assuming you're a nice guy - for uke to be rolling, their head is going to lead the motion but you are not smashing their skull into the mat. The zig zag can be a part of a leg sweep or a knee to the ribs, then a knee drop on the back of the shoulder.
What happens when you do hanmihandachi ikkyo? Specifically the variation with no large body movement.
When standing, are you having uke' decide to roll or are they already in flight and rolling?
