Thank you dear Ostad! Having a backup move is a brand new concept for me.
You said that in this form we practice to have balance and to fight in two different directions. This makes me think about the name of the mummay, atado, that should be "union of two things". Maybe it is also about directions?
Anyway, you said that most backups are plus directions. Could you please explain a little more? Are you talking about techniques in which I do something like attack or difence in one direction and than do another one at 90 degrees to the side?
If it is like this, for example when we do double mato vertical and Oranto with left hand, the following techniques at 90 degree Orato with right hand and left mato could these be backups? We had already done a previous attack on that side by grabbing and doing Mato punch, so could this have been a situation in which nothing happened? Or not?
I hope not to have messed up everything!
