Re: Fingers spread or together?
If good kokyu is applied the feeling of spreading the fingers comes out naturally but by keeping fingers together changes that feeling in my opinion. When training we emphasize the kokyu feeling to make sure that you feel it all the way from the centre to your fingers. In a fighting situation, I would clench my fists firmly and use Kokyu in a different way i.e. finishing the technique quicker by applying strike. So the open hand don't get 'in the way' but again it is hard to explain as they are so many various techniques with their variations to each one of them! But ultimately, I would keep the fingers spread for all kokyu exercise feelings...
