Thanks Huw. I've never heard the name and never tried it, although I suppose i've done variations.
Paul & I have been meeting up with some SKIF (Kanazawa) guys recently for a bit of extra practice. It's informal - not a class, we just train together, but we do their style of karate.
It's Shotokan, but there are some significant differences. There is more emphasis on circular movements, controlling your opponents enter of gravity, etc. Closer to bunkai type movements. The semi-free kumite that they do for gradings is very different too, and a much better progression towards free style. In fact, quite possibly a better progression towards self-defence style kumite too.
Each attack is done 5 times (5 oi-zuki jodan, 5 oi-zuki chudan, 5 mai-geri, 5 yoko-geri, 5 mawashi-geri and 5 ushiro-geri). There are 5 different defences for each attack. Starting with our basic defences (but with a little more body use/mowement), and building up to some quite complex defences with much more emphasis on evasion or controlling the opponent rather than simply blocking and striking.
It's great practice for us as it builds upon the basics practice that we've done for years. I think the downside to their approach for beginners is that there is less time to focus on the simple stuff. I think their body movement is better (although hard to say for sure because they've practiced these combinations a lot - we haven't), but they lack speed and power and their individual techniques are less polished than typical ITKF people. Although I have to admit their goals do seem to be different from ours. For instance, speed isn't so important - there is more emphasis on moving with your opponent.
In summary, I would say ITKF basics isn't enough if you want to be good at anything other than ITKF basics. But if you've only got time to train 3 or 4 times a week, then focusing on the ITKF grading syllabus is a good use of that limited time.
I don't think Kawasoe (or anyone else) has ever said that all you need is basics - just that until our basics are half decent it's a waste of time doing anything else. And he's got a point.
