This is part one of the fight between Mestre Ricardo De la Riva's and Royler Gracie for the “Cantão Cup.” De la Riva won by sweeping the Royler with his trademark guard. This was Royler Gracie’s first competitive defeat as a Black Belt. After beating Royler, De la Riva's highly effective guard techniques were simply called the "De la Riva Guard," which is currently used by the top fighters in the world to this day. This is truly an amazing fight and its great to watch each fighter attack and counter.
