Thought I'd finally add to this..
Very good points about classifying the objective and level of force as Rory had illustrated.. I think that's an important factor to consider when training in any system or style.
Here are some core WCK attacking concepts. WCK attack in a nutshell is about filling the space that exists between the core of your body and the core of the opponent with "stuff."
Once a new student asked my Sifu, "How does WCK protect itself?" And Sifu replied, "How do you keep people from getting into a room?" "Lock the door?" Asked the student.. "A lock can be picked or broken," Sifu said, he added, "A door can be kicked down or removed," "This kind of defense is weak." The student gave up, "So how do you stop someone from going into a room then?" "Sifu would always smile and laugh when giving the answer, "If you don't want anyone to get into a room, you fill it up with junk, bricks will work, then no one can get in the room."
In order for students to feel confident in and learning how to use a WCK attack they must be given some "way" of learning how to use and see the attack as a way of "defense", to use the centerline attack to protect themselves, against attacks that are coming or may come in just a moment. At first, students are shy, timid, they will hesitate to act and engage because they see engaging as dangerous or "risky." What must be taught to students one way or another is that, it is not attacking that is risky, rather it is NOT attacking that is risky..
So to protect the "room" and stay "safe" it is said one must fill the room up with junk, which in this case means a stream of unending attack. In the case of WCK the attacks fill up this center space with energy and leveraged body parts and continuous attacking moves, like striking, stepping, wedging, pressing, jamming, pulling, attaching, etc. These offensive elements actually fill the space that is directly between combatants providing a window of forward attacking energy that students are taught is there to protect them, a kind of offensive shield that must exist in order to remain "safe." This "safe" area of attack also creates a space to move through in order to continue with each movement and grind the opponent into hamburger ASAP.
WCK does not use fakes, nor does it teach to look for openings or ripe targets because of the time lag. The only “target” in the system is the center of the opponent and perhaps the opponent’s state of mind. Attacks to the opponent’s center generaly start from our center and move to their center. This ensures that power generated has the whole body behind it and always "attacks" the center of gravity of the opponent in order to break structure, provide an entry path and limit his ability to counter with any real power.
Since there is no attempt to disguise the attacks and since the attacks use the shortest fastest line they have a very good chance at making contact and also a good chance at surprising the opponent into a defensive mode <see flinch
>for just a moment. This is very important when WCK attacks because if you can get the opponent to “defend” a passive action, it allows the WCK attacker’s timing to move ahead of the opponent’s, as in attack > defend, attack > defend, once this advantage is gained the end is near.
Once this timing trap has been set the attacker is only reacting to our attacks and at this point the engagement will normally be at close quarters with lots of contact as the opponent struggles to maintain his degrading defense.
Now in contact WCK can fully express itself in all its nuances and take advantage of the special “conditions” that exist at this close range as the misuse of the line can be exploited much more so. As this stage a student will rely on his hundreds of hours of sensitivity training to go into an autopilot mode where he is able to accelerate his timing without use of thought or sight beyond that of most opponents. At this range the centerline is completely controlled using the opponent’s resistance. This allows transition into the last phase of the attack, where, having gained control of a clear and free line of attack all the nastiest finishing moves, strikes, kicks, breaks, cranks, etc., may be employed without further interference and with full power at point blank range.
That’s WCK attack in a nutshell.
