Dear Ostad Jalilzadeh thank you!!!Great, true! Your words makes me search to match them like two pieces of a puzzle!
Indeed Suto is very low, and in Atado there are some low techniques, and my mind goes to the low Mato before Haida, or at the beginning, Waimaduma left and two Matos down closing the knees as a defence from a...Haney Keyeto!!
But then...well I hope with this question you really won't get upset (Chinno affair...I know! Only for divide the energy and for balance because ratos are big so chinno is big too! I know it....I asked you too much about it and you have been so patient with me!!)
Chinno fisted in Suto may possibly be a technique to defend from the double matos to the chest in atado? those we make while turning the head 45 and eyes 90. Could it be that I try to come inside the opponent's defence, hit with the back of the fists and open the 2 matos aimed to the chest?
