Check out the sweep that worked on Fernando Margarida and the half-guard sweep that came in handy to Xande Ribeiro at the 2005 Jiu-Jitsu World Championship, in Rio de Janeiro. All with the Roger Gracie seal of approval. The Gracie will be seeing action at the July 14 Strikeforce show, where he’ll be facing Keith Jardine. Enjoy your studies and training!
