Dang! I am so sorry Ubaldo has gone from us so soon.
For the few years I have posted on this bulletin board I have come to know Ubaldo as a sharp but gentle critic, but more especially as a good friend. I was so much looking forward to meeting him in person next year.
Alas, this is not to be. However, I am sure, Renato, that your father has taught you all you need to continue training in you dojo in the best possible way.
In the meantime, please accept my deepest sympathy.
