The two faces of jiu jitsu: Every aspect of jiu jitsu has two sides – a positive side where my intention is to enforce my game upon my opponent, and a negative side where I attempt to prevent my opponent doing the same to me. So for example, in a grip fighting exchange, I try to impose my grips upon my opponent, whilst simultaneously negating his attempts to impose his grips upon me. When I pin someone and look to transition from one pin to another, I aim to position and hold myself in a way that maximizes my ability to move freely around my opponent, whilst at the same time doing my utmost to inhibit movement in my opponent. This dual nature of enhancing my aims while undercutting and negating those of my opponent is a key element of victory. Note that one without the other is without value. If I only care to impose my game without shutting down my opponents, he can move as freely as me and the result will be uncontrolled scrambles leading nowhere. If I only seek to negate what my opponent does without any positive movement and attacks of my own. I will never amount to anything more than an annoyance to my opponent by slowing him down without ever actually presenting any danger to him Here, eddie cummings exhibits a fine example of this duality. He has attained a position where he can readily move his body in the appropriate directions to apply crushing force to the leg of 10th planet black belt champion, Nathan Orchard, while at the same time completely eliminating Mr Orchard's ability to move in a way that would allow escape. This creates a huge imbalance in movement potential that leads to decisive victory.
