Yakusoku Kumite

Here is a video of Higaonna Sensei demonstrating applications of technique in the yakusoku kumite style. Yakusoku kumite is one of the forms of ippon kumite, where one practitioner attacks using a single, predetermined technique, such as chudan oitsuki or chudan maegeri, and the other karateka blocks and counters accordingly. For beginners, the counter attack usually takes the form of a single strike, but as the practitioner's level advances, the responses become more complex and varied, ideally incorporating applications from the higher-level kata. This should be the approach of all yudansha or black belts.  In the video, the techniques are demonstrated once slowly and then again naturally and swiftly.
