2 Part Technique - If you notice that one of your opponent's knees is far from the mat while he plays Butterfly Guard, take advantage of the position by knocking his legs for the Folding Pass. Immobilize his hips with Double Under Control, containing his escape routes by blocking his lateral movement. If he begins to build a frame for retracting his hips out from underneath your control, forgo the Double-Unders and clear his posts. If he is particularly insistent on escaping this way, latch onto his head as he escapes his hips away with a Guillotine Choke. Once on his neck, if he is defending against the choke, gain more control with the Front Headlock vs Half, and look to pass to either Side Control or Mount.
