Absolutely. But then that would not be chi sao would it?
What? Free fighting? Of course not. Or do you mean not using sensitivity to fight people throwing punches at us? You mean you try to chi-sau a guy as he's punching at you? How's that going?
Ok, but that is also a byproduct of the training it isn't that one does so without practicing in contact with another.
It's a byproduct, says you. I don't think you understand what byproduct means. It's often an unintended or incidental product. What I've been describing are the actual purpose of our training; to condition these automatic behaviors for fighting.
When WSL said sensitivity is a byproduct of the training, but not the goal, he meant that it's an unintended and incidental result of mutual contact training in chi-sau drills, but we don't focus on developing it to use in a free fighting strategy where there is no pre- or prolonged arm contact. People who base their system on this type of thing often look for connection in sparring / fighting and end up eating punches.
Ok and most striking type fighting has only short instances of contact. Again not chi sao and can be taught without chi sao training.
Other striking systems don't use our methods. Chi-sau is a stage used in the development of our striking methods. And if you think there will be long instances of contact when punches are being thrown at you at lightning speed, it's likely to be you in contact with the floor...
Ok.
I agreed with everything here and when one is in a position where your one arm is trapping or controlling the opponent's two arms you telling me you don't feel that? And when the opponent moves an arm or changes angles you don't feel that either?
I think you are oversimplifying your concept of "feeling" to just mean physical sensation, as in a faculty of a normal human being, so that I'll concede that I use your methods too. But what you really mean by feeling, in the context of your system, is some sort of ting-lik, "listening to energy" skill that is developed through your chi-sau training, isn't it? You do not simply mean the faculty of any normal sentient human being having awareness of physical contact, as that would not require chi-sau training to develop either.
I don't know why you want me to agree with you. Would that validate your method? We do different things. I don't over-trap by sticking to an opponent's arm to feel or "listen" to their energy and attempt to manipulate it in some fashion or choose my next move based on what I sense.
I displace and strike with a single limb in a single action. Even when using a helping hand to displace and open the line for striking with pak / jat / bong, etc., the displacing limb immediately recycles to become the next striking hand in order to continue the flow of attack. The centerline is controlled by spatial domination, not by sticking and over-trapping.
It's hard to wrap your head around if you aren't familiar with the method, but hopefully I've explained enough for you to drop the idea that I must be using feeling like you. What would make your Wing Chun different from any other martial art, since any normal human being also feels when contact is made?
