This footage was taken at a residential course in June 2014. At the course, all participants were asked what topics they would like to cover. One suggestion was the bunkai for Shotokan’s Tekki-Nidan (Naihanchi-Nidan). I’m not a Shotokan stylist and the school I originate from only practises one version of Naihanchi. Tekki-Nidan is therefore not a kata I practise or have spent much time analysing. In preparation for the course, I familiarised myself with the kata and had some initial thoughts.
