From a seminar yesterday I picked up an interesting perspective on one small aspect of training and my mind started expanding on the thought.
To provide context it was a grappling seminar. The technique in question was the combative stand up, initially as a solo exercise but quickly put into practice as an escape from closed guard to regain the feet. The instructor taught that the closed guard is essentially a neutral position so movement in either direction is appropriate. On that basis make the stand up specifically to end up in your dominant guard for the next aspect of the fight. I'm a southpaw so I deliberately stood such to end up right foot forwards ready to grapple, strike or escape depending on context (pragmatism vs sport,) personal preference, the actions of my training partner and so on.
To do what degree is ambidexterity necessary?
We know that kata often teach the same motion to both sides depending on the attack. We also know that sometimes the motion may be performed on both sides but actually it's responding to different attacks. Often the transitions that matter not the final position. Often things are performed one sided.
Years ago whilst training in Karate I was taught a view erroneously attributed to Funakoshi which went to effect of train your good side ten times and your bad side twenty. Alternative one of the Gracies (Hickson I think) maintains that you only need to be able to work off one side, but you must be able to make that one side work against attacks from either side.
So how important is it to be able to use both sides? Or is it important at all?
