Thanks for the response fellas,
Chris,
You've put me on the spot now!
The book you cited did make mention of it yes, but I'm sure I remember one of my teachers, who had studied with Rose Lee in London, telling me that as a child she had met practitioners such as Sun Lu Tang and tried using her Hsing Yi to attack him but always found him behind her.
This of course is anecdotal, and comes third hand so I can understand your skepticism. I could also except that the concept of getting behind the opponent is the equivalent of an old wives tale; if it wasn't for the fact that the training lends itself to developing this skill, what with the footwork and all. There is also the argument that because out flanking an opponent is a such a large part of the bagua gameplan, that getting behind is only (forgive the pun) a small step to make.
I get your point about people flailing around if they are caught with someone behind them, but I have also witnessed people in a state of momentary paralyzed confusion when this strategy is used; and just for the sake of argument (its a slow day at work
), I don't agree that this definitely wouldn't work in a "real fight". A fully committed attack has an aspect to it that (if timed correctly) is perfect for this type of thing, and also spinning, body sticking and tying up opponents. Are they easy to pull off? not really, but they can be very effective when you do.
The down side as I see it is that as a technique, it must be used sparingly. If your opponent has any type of savvy, it will become predictable very quickly. But that could be said for a great many things.
As a side note, switching tact is a large part of the appeal that bagua holds for me. Sometimes straight sometimes squirly! Getting behind someone is quite rewarding IME because it opens a lot of avenues that otherwise wouldn't be there.
