I found these series of videos while looking for some alternative bunkai for the pinan kata. I found this gentleman's interpretations elegant. The videos for Shodan and on can be found on the side bar. The only thing I disagree with, and maybe someone can shed light on this and perhaps I can see some light is defence against wrist grabs. I've always been taught that if someone is stupid enough to get close enough to grab your wrist your only response should be to punch them in the face, or other vunerable target rather than attempt any of the more complex, and I use that word loosely, movements. The only reason that I can think of is that it puts their head in a predictable location, rather than aiming a punch towards someones head you can do some sort of wrist/arm lock and by using the wonderful tool of pain, put their head in a location that it will stay until you can deliver a blow. Anyway, I digress, enjoy the video.
