I started this thread based on one of LFJ's post. Many WCK practioners rely solely on chi-sau as their sole method of sparring because they feel it's a safe environment to build skills while minimizing injuries. but unfortunately Chi sao does not address moving through different ranges, how to get it, or the stress inoculation involved. I use a system of angular footwork to "cut off the ring"which I refer to as chi sao without touching . What are some training methods you employ to address these aspects of fighting?
