In a modern fighting context one has to be prepared to defend against punches coming rapidly from multiple angles. This is true whether the opponent has an actual boxing/kickboxing background, or is just a street punk with some fighting experience. You can expect these punches to be coming fast enough and at all kinds of angles that make it difficult to nearly impossible to block or parry them all. These leaves you with two basic strategies: 1. Charge in with your own punches and hope you can parry some of his initial blows until you can overwhelm him with your own. From a Wing Chun perspective maybe you can trap him or otherwise prevent him from continue to throw punches. 2. Fight more defensively with "covers"....like a boxer does, and watch for openings in which to throw your counters. This is more "weathering the storm" and "returning fire." Strategy #1 can work, but typically does not defend the head well and one can easily take a shot on the way in. There is also a problem here if your opponent manages to avoid your initial onslaught or move away. Then you have to re-engage and risk taking a shot all over again. This really is an "ambush style" of fighting. You close in quick and hope to maintain control the whole time. It isn't very good for "face off"..."back and forth"....kinds of fighting. And you see this regularly when you watch clips of Wing Chun guys sparring....that is if they make an effort to actually stick to their Wing Chun! I saw a Wing Chun sparring clip recently where one guy just charged straight in throwing wide punches from the shoulders rapidly the whole fight. He didn't even try to throw nice straight Wing Chun punches. His opponent kept the typical forward guard thinking he was going to parry things. Well, he didn't stop a single punch because they just went around his guard faster than he could respond. And he had no idea how to cover his head. So he took multiple punches to the head and was knocked down about half a dozen times. He looked like he had no defense at all because his opponent was throwing wide punches rather than nice Wing Chun centerline punches. And neither of these guys were beginners to Wing Chun! Strategy #2 is safer, and ends up being what most people do when they spar. People will instinctively start to "cover up" when blows are coming at them fast and hard. 52 Blocks specializes in "covering up" in this kind of scenario, even more so than western boxing. But this strategy of "covering up" to "weather the storm" rather than blocking or parrying as your main defense is central to both. And this is what works best when someone is raining down fast punches from multiple angles. So the bottom line for me.......Wing Chun would do well to learn how to use these covers and the footwork from Boxing/52 Blocks in order to manage distance and close safely with an opponent. Then when in close, the Wing Chun can kick in with sticking skills and close-range striking and controlling.
