Strategy in Movement one of Dafanche
In the Qixing Tanglangquan version of Dafanche we have the move:
撇 捶 右 單 鞭 - piē chuí yòu dān biān - Casting Strike, Right Single Whip
Tonight I touched on one strategy of this move in class. Though I may be "preaching to the choir", I thought someone might benefit from my explanation.
The casting strike is a long arm, outward swinging back-fist type motion. It is followed by a long range, inward swinging hook strike.
I explained to my students that the initial strike, if done as in the form, is a very easy to anticipate attack. I believe that this intentionally inspires (叫 - jiào - provoke) the opponent to extend his left arm to block and create an opening. The left casting strike converts to a grab (粘 - zhān - paste). The right leg steps in contacting and pressing against the opponent's left leg (貼 - tiē - lean), while the right hook punch strikes the opponent in the head. Alternately, the right forearm can contact the opponent's neck to uproot.
In this situation, the casting strike is a misdirection (虛 - xū - false), while the single whip is the intended strike (實 - shí - real).
Note: I often use the quanpu of Master Wong Hon Fan because it is very clear and concise. Yet, that does not mean his descendants will all necessarily agree with the interpretation.
