The Gracie challenge and their participation in countless free fighting events has led to a different emphasis in fighting strategy and the development of unique rules for BJJ sport competition. Even the rules of sport grappling matches are designed to ingrain the proper strategy to be applied in the street. For example in a sport BJJ match, points are awarded based on achieving superior positions, positions from which not only grappling techniques can be more readily applied, but also from which strikes may be applied or defended. Students naturally seek the positions that will garner them the most points, thereby constantly reinforcing the most efficient strategy for real life confrontations. This "position-submission" strategy has proven to be the most effective for real life confrontations.
