2 Part Technique - If your opponent counters your Knee Slide Pass with Collar & Elbow Control, by blocking your knee with his hands, remove the impedance by concentrating on his near hand rather than his far; The nearside hand is the one that is stopping your knee from passing through. Switch from the Collar & Elbow to a 2on1 Control on the arm that is in the way and stretch it across his chest. Cut your knee through, drop your hip to the mat, and immediately look to pummel for the farside underhook before he has a chance to foil your pass. If you meet strong resistance to stretch the 2on1 across his body, abandon the Knee Slide for the Leg Over Pass vs Half Guard instead. Cut your knee to the opposite side and kick your free leg over his head, hence the name. Land your hip onto the mat and pummel for the underhook. All that is left is for you to free your foot from his half guard and establish the Side Control with Underhook & Head Control.
