“Before he died, he told me that “jeet kune” meant Pak sao in wing chun or intercepting an opponent’s punch before it landed on you.”
This is an excellent interview with Hawkins Cheung, an early Ip Man student and close friend and training partner of Bruce Lee. He was also a “Kung Fu Uncle” to my teacher Greg LeBlanc – he used to come by the Gary Lam house often and answer questions and help with the teaching. I am especially interested in his frequent references in this article and others to the importance of the”Jeet” concept and developing the timing to enter from outside to inside the fight. This has also been my experience. The big question mark is in those first seconds just before the fight kicks off. This is something also covered in a lot of detail by Geoff Thompson, who pretty much suggests that you learn how to preempt and sucker punch. A friend of mine who in many street fights also emphasized this point. His advice was basically to gauge your distance, decide when you would hit (if he steps over this line), and where you would hit, and then to preemptively attack. The Jeet concept really encompasses all of that but rather than sucker punching, its more like a old-fashioned gunfight. You get your hands up (a Thompson “fence,” aka hand just over the gun). As soon as the opponent starts to move (car out of the garage and into the driveway but before it gets on the street, in Greg LeBlanc’s terminology), you attack. If the line isn’t clear and you contact an arm on the way in (a bridge) you use the Chi Sao reflex to do the appropriate action (Pak, Lap, Tan, Bong) and either hit (best), block and hit simultaneously (second best), or block then hit (if you can’t do 1 or 2).
Bruce Lee learned fencing-type footwork to dart in and out of range to handle this conundrum. Once you develop Wing Chun skills, this becomes the main thin to learn. Some call it timing.
