Hi Andrew,

smaller/weaker- ‘weaker’ is a disingenuous term. In reality, one wishes to maximize one’s strengths. If a set of body mechanics can allow someone 80-90lbs lighter than another person to throw the larger person around like a rag doll, they’re stronger, no matter who has the higher bench/squat/deadlift numbers.
Hmmm. This is only a metaphor for us. We don’t surgically alter our physical selves to achieve some puny, weak ideal. Another way we express our ideal of Wing Chun is that if a small woman cannot do it, it isn’t really Wing Chun, but if a small woman can use it to control a stronger person (with higher bench/squat/deadlift numbers), that is the ideal. Sandy Wong, Ben Der’s longest student, along with Ben himself, exemplify what Wing Chun can do for us.

inside hands- there are a couple of places I disagree with you here. It is of great advantage to be very close in, at the point your strength is maximized (again, if you hurl someone across the room, I consider you strong, whether you are a powerlifter, Wing Chun player, taiji man, or Bob Sapp).
[/B]
Strong is not in our lexicon.

The ‘sweet spot’ for your power probably exists at each point along the body, with some mobility, compensatable by some torso stuff, so for purposes of this discussion, lets assume we’re primarily thinking about expressing power through the hand/wrist parallel to the sagitally plane. With these restrictions in mind, here is the obvious logical flaw to your argument- if one person has longer reach, is larger, they will not be operating at optimum position if they try to work inside the optimum position of a smaller person/ person with shorter reach.
[/B]
This conclusion comes from the awkwardness of expression in this medium. Of course, for every individual, there is a different distance, but for the smaller person to work inside the ideal distance of the larger is an advantage. Obviously, the larger person will want to work at their own distance. So, if you’re picturing yourself against a larger person, where would your ideal position be? I might work inside or outside in this case, depending on the opponent or partner’s relative skill and style, but I train to be comfortable inside, which you won’t see much in other Wing Chun in my experience, although or because working inside requires the most skill and confidence in one’s hands. Fundamentally, we want to be in control and working at our distance.
[B]
Good structure/ good mechanics/ relaxed body usage, all these can still operate on the outside,
[/B]
No argument on that.
[B]
but I would argue that on someone smaller than you trying to force yourself to work inside can prove to be a disadvantage, especially when you now bring into consideration not only reach with arm length providing the hypotenueus of the triangle being used to wedge in, but the breadth, the distance from shoulder to shoulder, the base of a wedging triangle. While there are many other factors involved, looking solely at the upper body (not implying that this is the primary source of strength), the optimum angle for force delivery at a given limb length, probably changes with increasing broadness of the shoulders- as the base of the triangle gets wider. A more obtuse angle of arm to body seems to support force transmission better (I think this may be generalizable), hence the superiority of the elbow in position. At the same limb length and increasing shoulder breadth, two people will have different mechanical advantages at the same range and it will be to one person’s advantage to be closer (and I need to go dig out my Feynman’s and check the chapter on levers to figure out who this is).
[/B]
Don’t bother with Feynman for my sake.
I agree that wider shoulders may give the larger person a better angle for working outside. I haven’t thought about whether it precludes working inside. I don’t envision it doing so in my mental chi sao. Another difference between Ken Chung’s teaching and some others, we don’t think in terms of triangles, but I see the utility in this analogy.

Uh, long rambling on one of my present problems aside- the bottom line is that ‘inside’ is not the best place to be for every person at every instant. Unless you are Yip Man’s size, you will wind up treating larger and smaller opponents differently because of differing points of contact and mechanical advantage on contact (i.e. if you’re taller, you will tend to make contact on the outside, ‘fishing’ to get inside seem rather silly if you can crush them from where you are).
[/B]
I’ll have to work this out on some likely victim when I return to class. I don’t agree that I/we are fishing for the inside; we just go there when it’s the thing to do. If I can crush my opponent from where I am, then that’s the most direct response. We don’t add movements or technique complications. We’re always looking the simplest response.
[B]
Closing the gap- yes, I have no problem saying that in WT we perceive that as a major issue, and handling problems during that is one thing for which we train chi sao. Once in, the ideal is to be **** close (elbow a fist-length or off the ribs, front leg pressing and active), but ideally not to be there unless the other person’s ability to strike back has been drastically curtailed.
[/B]
We don’t consider closing the gap to be a problem. We expect our opponent to do it for us in most cases, but once engaged, which can be from across a room, we work to find our ideal position. We step to bring our weapons close in. We don’t use so-called long-range weapons such as lunges or high kicks. The elbow position you describe is for us too, but we don’t have a front leg—both are legs are in a neutral side-to-side stance unless there is an opening to fill. A leading leg is a liability IMO, because one cannot defend equally on either side. Finally, we are comfortable close-in because we assume that we will be able to shut down an opponent’s offense before they can launch it.
[B]
Staying close and controlling- perhaps I’d view that more as a tertiary goal, focused on at a later phase of training. In an ideal world- someone thinks to attack, I hit first and attack until they’re incapacitated. In a less ideal world, they attack, I move and hit them, never contacting the attack or being in their line of fire. Less ideal, I must deal with the attack by bridging, and hitting, again destroying their ability to reply. Less ideal yet, I bridge, get close, and they can still reply, then I control and hit, until I can attack unanswered.
[/B]
I guess I consider the last to be the ideal. Not that I’d be doing chi sao on the street, but by controlling them and then striking, I’m not being greedy or afraid. Sometimes the urge to strike is based on fear of not being in control of the situation. Absorbing the opponent’s force and defusing their attacks, eating their hands—as Ken says—gives us the maximum security and the maximum offensive opportunity.
[B]
This last one, dealing with another Wing Chun player, is pretty low on my priority list, and I work this more against a covering boxer, kicker trying to break distance, or grappler closing for a tie-up (often off a punch or kick).
[/B]
This is another difference between us. Since Wing Chun has the best angle on the centerline and the most control, matching against Wing Chun gives me the biggest challenge.
[B]
Through this I always wish to preserve the ability to move out should someone else come along.

What has your dating life got to do with it?
