The problem with techniques is orthodoxy.
A self defence situation calls upon you to adapt and change relative to the opponents behaviour.
This requires a dynamic relationship.
There is no fixity.
You cannot make any assumptions concerning your opponent.
Every encounter is fresh, alive and changeable.
The variables are considerable, and you must move with them, flowing and fluid.
Your appropriate response is akin to building your own technique, tailored specifically for the attacker and discarded when you break contact.
It lives only as long as the attack does and is not the product of conscious thought.
