This is a new type of competition called: True-to-Form Sparring in USA Chin Woo
I copy and paste their rule from
http://www.legendsofkungfu.com/rules.html#true TRU 2 FORM TRADITIONAL FIGHTING
General Overview
It is recommended that students have 1 year or more experience before participating in this event. This is the first time in years that an attempt is made to create a solid traditional-based fighting event. We will need the cooperation of all practitioners that see the merit of this event in order to make it a success. Individuals will be matched according to their level and experience. If you are an assistant instructor or intern at your school with more than 6 years experience, you will be placed in a category called "Tru Disciple". A practitioner of this level should be able to execute their system to a very high degree of skill. This is the very goal of 'Tru 2 Form'. Anyone who enters the Tru 2 Form category is a true patriot of Chinese Martial Arts (CMA). This division is not about who is the best. It’s about maintaining and further developing the spirit of CMA.
Basic Rules
1. STP- speed, timing and placement of your technique must be applied. The key is to attack your opponent with such skill, class and grace, that you are able to easily control the opponent by executing your attack with finesse and accuracy. This shows your ability and control.
2. You will be judged on your ability to stay in character of the system that you represent on its defense and offense.
3. There will be no points presented. You will be judged on your overall ability and reaction to your opponent within a 3 minute match.
4. If it's clear to the judges that after the first match that one individual clearly dominates, there will not be a second round.
5. It's up to the practitioner to demonstrate his/her ability to the highest level possible, with little to no injury.
6. As Tru 2 Form develops, so will the contact. (ex: reaction skills fighting -> light contact -> full contact)
7. Individuals will come together under the guidance of a center referee and 4 corner judges, salute, and take their fighting positions. Referee starts the action. The corner judges are watching each individuals’ every move, defense and offense, making a mental decision on which fighter was Tru 2 Form.
8. At the end of the match, judges and referee come together to declare the winner. Please note that this event is new and developing.
