Is a simple motion (punch or kick) which moves with no effort to conceal it, directly to the target on the most economical route.
It can also be indirect, beginning on one line and ending on another.
Such as a punch that starts to the stomach (mid line) and ends on the chin (high line).
SAA is an attack that is launched from an unanticipated angle that is achieved by moving in such a way as to create an open line into which to strike.
- Attack By Combinations (ABC). This is using multiple rapid attacks, with volume of attack as a means of overcoming the opponent.
- Progressive Indirect Attack (PIA). Simulating an attack to one part of the opponent's body, followed by attacking another part, as a means of creating an opening.
- Hand Immobilization Attack (HIA) and its counterpart Foot Immobilization attack, which make use of trapping/parrying to limit the opponent's function with that appendage.
- Attack By Drawing (ABD). The goal when using attack by draw is to "draw" the opponent into a committed attack by baiting him into what looks like an exposed target, then intercepting his/her motion. One can execute a motion that invites a counter, then counter attack them as he takes the bait.
Centerline
The Wing Chun centerline.
Punching from the Wing Chun centerline.
The centerline can be expressed as the height of a triangle.
An animation of mechanical linkage to the shoulders of our triangle illustrates the importance of guarding our centerline.
The centerline is an imaginary line drawn vertically along the center of a standing human body; and also refers to the space directly in front of that body.
If we draw an isosceles triangle on the floor, for which our body forms the base, and our arms form the equal legs of the triangle, then h (height of the triangle) is that same centerline.
The Wing Chun concept is to exploit, control and dominate an opponent's centerline.
All attacks, defenses, and footwork are designed to guard your own centerline while entering your opponent's centerline space. Lee incorporated this theory into JKD from Wing Chun.
The three guidelines for centerline are :
- The one who controls the centerline will control the fight.
- Protect and maintain your own centerline while you control and exploit your opponent's.
- Control the centerline by occupying it.
This notion is closely related to maintaining control of the center squares in the strategic game chess.
The concept is obviously present in Xiangqi (Chinese chess), where an "X" is drawn on the game board, in front of both players' general and advisors.
