The basis of jiu jitsu – Take away an opponents freedom of movement: An opponent who is free to move as they please is a dangerous opponent. One of the cornerstones of jiu jitsu is the idea that you must be able to control an opponents movement in order to control the outcome of a fight or match. Control of movement comes in degrees. It starts with something as mild as a wrist grip and builds up to control of the hips and core, becomes still more powerful when you go to the ground and can use the combination of floor, gravity and your body forming blocks and wedges to make movement very difficult for an opponent. It culminates in situations where you have your legs controlling your opponents upper body preferably on top of him so that he finds any kind of movement extremely difficult. Learning to progressively gain greater and greater control over your opponents movement is close to the very soul of jiu jitsu and is the element of the art that allows you not only to win – BUT TO CHOOSE HOW YOU WIN AND WITH WHATEVER DEGREE OF VIOLENCE, RANGING FROM VERY MILD TO EXTREME, YOU CHOOSE. Don't accept situations where an opponent stands unfettered in front of you – make contact early and progress rapidly to greater and greater contact until you have complete control. This is the spirit of jiu jitsu
