The WC I practice has long range bridging strategies. It is part of our Cheurn Kiu Sau engagement tools. This can be used to bridge with an opponent as a means of keeping them out of mid-to-close range striking. Of course, it also would keep me out of that same range, but in a general sense, it's intent is to intercept & engage with an opponent and fend them off to prior to closing the range into WC's short range striking. This may be done as a means to feel the guy out a little before commiting to striking. When introducing these ideas to students, I use the analogy 'touch the stone, cross the river'.
Of course, the opponent might have other ideas, so it doesn't always work out and the range may be lost before it's of any use.
