It is essentially open combat with controlled attacks using all available means and methods. In order to prevent injury, protective equipment is worn.
The evaluation of free sparring is based on accuracy, speed, timing, distance, and quality of technique executed. Balance, blocking and dodging skills, and attitude are also very important.
Because each of the participants is free to move and attack, free sparring encourages the development of strategies for attack and defense, while improving speed and timing. Since free sparring is practiced as a non-stop fight that may consist of one, two or three rounds, being in top physical condition is very important.
