Brazilian Jiu-Jitsu is a martial art, combat sport, and a self defense system that focuses on grappling and especially ground fighting. The art was derived from the Japanese martial art of Kodokan judo in the early 20th century.
It teaches that a smaller, weaker person can successfully defend against a bigger, stronger assailant by using leverage and proper technique—most notably by applying joint-locks and chokeholds to defeat the other person. BJJ training can be used for sport grappling tournaments (gi and no-gi) and mixed martial arts (MMA) competition or self defense. Sparring (commonly referred to as 'rolling') and live drilling play a major role in training, and a premium is placed on performance, especially in competition, in relation to progress and ascension through its ranking system.
BJJ is most strongly differentiated by its greater emphasis on groundwork than other martial arts. Commonly, striking-based styles spend almost no time on groundwork. Even other grappling martial arts tend to spend much more time on the standing phase. It is helpful to contrast its rules with judo's greater emphasis on throws, due to both its radically different point-scoring system, and the absence of most of the judo rules that cause the competitors to have to recommence in a standing position. This has led to greater time dedicated to training on the ground, resulting in enhancement and new research of groundwork techniques by BJJ practitioners.
Along with BJJ's great strengths on the ground comes its relative underemphasis of standing techniques, such as striking. To remedy this comparative lack, there is an increasing amount of cross-training between the sports of BJJ and wrestling, Judo, or Sambo, as well as striking based arts such as Muay Thai, kickboxing, and boxing.
Sport Brazilian Jiu-Jitsu's focus on submissions without the use of strikes while training allows practitioners to practice at full speed and with full power, resembling the effort used in a real competition. Training methods include technique drills in which techniques are practiced against a non-resisting partner; isolation sparring, commonly referred to as positional drilling, where only a certain technique or sets of techniques are used, and full sparring in which each opponent tries to submit their opponent using any legal technique. Physical conditioning is also an important part of training at many clubs.
Style of fighting
Brazilian Jiu-Jitsu emphasizes getting an opponent to the ground in order to utilize ground fighting techniques and submission holds involving joint-locks and chokeholds. The premise is that most of the advantage of a larger, stronger opponent comes from superior reach and more powerful strikes, both of which are somewhat negated when grappling on the ground.
BJJ permits a wide variety of techniques to take the fight to the ground after taking a grip. Once the opponent is on the ground, a number of maneuvers (and counter-maneuvers) are available to manipulate the opponent into a suitable position for the application of a submission technique. Achieving a dominant position on the ground is one of the hallmarks of the BJJ style, and includes effective use of the guard position to defend oneself from bottom, and passing the guard to dominate from top position with side control, mount, and back mount positions. This system of maneuvering and manipulation can be likened to a form of kinetic chess when utilized by two experienced practitioners. A submission hold is the equivalent of checkmate in the sport, reflecting a disadvantage which would be extremely difficult to overcome in a fight (such as a dislocated joint or unconsciousness).
Renzo Gracie wrote in his book Mastering Jiu-jitsu:
'The classical jujutsu of old Japan appeared to have no common strategy to guide a combatant over the course of a fight. Indeed, this was one of Kano's most fundamental and perceptive criticisms of the classical program.' Maeda not only taught the art of judo to Carlos Gracie, but also taught a particular philosophy about the nature of combat developed by Kano, and further refined by Maeda based on his worldwide travels competing against fighters skilled in a wide variety of martial arts.
The book details Maeda's theory as arguing that physical combat could be broken down into distinct phases, such as the striking phase, the grappling phase, the ground phase, etc. Thus, it was a smart fighter's task to keep the fight located in the phase of combat that best suited to his own strengths. Renzo Gracie stated that this was a fundamental influence on the Gracie approach to combat, these strategies were further developed over time by the Gracies and others, and became prominent in contemporary MMA.

Side Control
In side control, the practitioner pins their opponent to the ground from the side of their body. The dominant grappler lays across the opponent with weight applied to the opponent's chest. The opponent may be further controlled by pressure on either side of their shoulders and hips from the practitioner's elbows, shoulders, and knees. A wide variety of submissions are initiated from side control.
Full Mount
In the mount position the practitioner sits astride the opponent's chest, controlling the opponent with their bodyweight and hips. In the strongest form of this position the practitioner works their knees up under into the arm pits to reduce arm movements, limiting their ability to move or counter the submission attempts. Full Mount is can be used to attack the arms (with arm and shoulder locks), apply choke holds, or to utilize the triangle.
Back Mount
When utilizing the back mount (often known in Brazilian Jiu-Jitsu as the back grab or rear mount), the practitioner attaches to the back of the opponent by wrapping their legs around and hooking the opponent's thighs with their heels.Simultaneously, the upper body is controlled by wrapping the arms around the chest or neck of the opponent. Commonly the opponent will be pulled up on top of the attackers chest to execute this technique. This position is often used to apply chokeholds, and counters much of the benefit an opponent may have from greater size or strength.
Guard
In the Guard, the practitioner is on their back controlling an opponent with their legs. The practitioner pushes and pulls with the legs or feet to upset the balance and limit the movements of their opponent. This position comes into play often when an opponent manages to place the practitioner upon his or her back and the practitioner seeks the best position possible to launch counter-attacks. This is a very versatile position from which the BJJ practitioner can attempt to sweep (reverse) the opponent, get back to the feet, or apply a variety of joint-locks as well as various chokes.
The three main types of guard are Open, Closed, and Half. In closed guard, the bottom grappler has their legs around the opponent's trunk and has their ankles closed together to provide control and a barrier to escaping the position. In the open guard, the legs are not hooked together and the bottom grappler uses their legs or feet to push or pull in a more dynamic fashion. In the half guard, one of the top grappler's legs is being controlled by the bottom grappler's legs.
