As an addemdum to my last post, here are my 10 BASIC rules of a good uke. The operative word here is BASIC.
1. Present a committed, continual, focused attack
2. Do not retreat, go limp, be stiff, or plant yourself; that is not an attack
3. When working with beginners do not try to regain your balance
4. When working with senior students try to regain your balance but don’t fight
5. Intensity and resistance should be appropriate for your partner’s current level
6. For beginners be a constant
7. For senior students be a variable
8. Protect yourself at all times
9. Make sure both left and right sides of your body are capable of attacking and receiving
10. Always feel for openings and opportunities to counter but do not exploit those unless it is part of the current practice
This is not meant to be a comprehensive or definitive list but it is a good general policy that we in my dojo operate under.
