Jujitsu is a combination of thousands of locking and throwing movements that work a lot like a chess game where both opponents have to plan each and every move using a lot of strategy to get the right edge, because once one opponent has the other in a neck or arm lock the other is at his mercy and it’s the dominating opponent’s decision to either let the other free or break his arm, leg or choke him altogether.
There are several later forms of Jujitsu, the most popular one of which is Brazilian Jujitsu. In this form of Jujitsu, many new moves have been added and the fighting form has thus gone through somewhat of an evolution. This fighting form is presently known as the best form of unarmed combat in the world.
