I’ve seen this so many time in aiki “sparring” - just two people who ought to know better reaching and grabbing for wrist and arm control.Some (not you) may think one can just initially go for head control or joint lock, but we know it's seldom that easy. Chin Na master, Zhao Da Yuan wrote, "...in a fight it is impossible to grab an opponent and apply Chin Na directly..." Some initial "tenderizing" is normally required. Just thought this point worth stressing.
