I think you misunderstood my question. I'd like you describe me how to make waza work with very small committed, but correct attacks. Good attacker will not commit too much, do you agree?
Too generalized a question. When you talk about small committed, correct attacks, are you referring to in-close striking and grappling? Waza is simply the end point of a number of processes. My invitation to you was sincere and I think that you can easily understand how to enter, without colliding in order to execute techniques after spending a weekend playing with Ushiro Sensei. I look at waza as kata. Proper practice which emphasizes the development of underlying principles enables a person to be able to become increasingly capable of managing ones' self amidst conflict. When you get too caught up in trying to make your waza work, you are already behind.
