This video was filmed in Stuttgart, Germany in June 2012. It covers some general bunkai concepts and primarily looks at an arm-lock and associated escapes found within Heian Shodan (Pinan Nidan). The second part of the video also shows how a flow drill can be created by getting your partner to counter the counter, which is in turn countered using a motion found in Heian Yodan (Pinan Yodan). This is just a short impromptu clip taken from a full weekend of teaching. I nevertheless hope you find the information presented in the clip interesting and useful to you.
All the best,
