3 Part Technique - Keep your feet strong and controlled against the opponent's body, because playing Open Guard with loose feet exposes yourself to foot locks. Place your foot against the opponent's hip to keep distance and attack with the Tripod Sweep. If the opponent drives forward with poster against your Open Guard, while preventing any upper body controls from being established, offset his balance with De La Riva. The opponent will commonly Back Step or attack your leg with a knee bar. Swim your free foot inside, protecting your legs, while exposing the opponent's back.
