Is there a difference in the way "pins" (any of the variety of chest on chest hold down such as side control, north-south, some versions of the mount, etc.) are performed in BJJ that are different than Judo?
I understand that in Judo a pin is often times seen as an end, since one can win by pin/hold-down in Judo, wheras in BJJ it is seen as an important "means" to an end (the submission), so my question is not necessarily about which practitioner's arts are able to exert the most pressure of have the greatest a bility to keep a person down in a pin (a chest on chest type pin is what I am referring to). But my question is about as to whether or not they use different types of grips, have different theories about hip placement, or where to exert pressure, etc.
Anyone who has dabbled in, or grappled with practitioners of, both arts, please provide some insight.
