Simultaneous Attack and Defence in Chi Sau

Following on from the last post, do we use or can we find Simultaneous Attack and Defence in our Chi Sau practice? Lately we have been having a closer look at Chi Sau and Chum Kiu especially focusing on the Concept of the "Spinning Ball" for defensive duties and the "Spinning Cone", or "Witches Hat" for attacking duties, but what about Simultaneous A & D? Sometimes we forget that Chi Sau is nothing more than a Drill, a dynamic environment in which we can explore and try out the things that the various Forms show us, and that it is up to us to look for our training in Chi Sau and not just be shown "Moves". If the "Spinning Ball is defensive and the "Spinning Cone" is attacking then Simultaneous A&D must contain both. In Chi Sau the first part of the Taan Sau / Bong Sau rotation is the Man Sau or  Searching Hand, when intercepted this redirects the force away by turning into Bong Sau, but if it is not intercepted it continues forwards to strike, while this is happening we are applying pressure through our Fook Sau to our Partners attempt to roll from Bong to a striking position, at this point we are utilising the concept of "Simultaneous Attack and Defence", if we think the situation is open to perform the Basic Fook Sau Latch it is usually here, and of course any other Gwoh Sau application is also using Simultaneous A&D. Often advances in understanding come from simply looking closely at what you are doing, observing your actions and reactions to the dynamic exchanges that make up Chi Sau and then doing them deliberately when the chance allows.
