2 Part Technique - If you want to transition into the 1-Leg X-Guard from your Butterfly Guard while your opponent stands, you have to keep your hook flush against his shin, following his foot and leaving no gaps. If he keeps your hands busy and crosses his knee for a pass, lift his leg up off the mat with your hook to stop his progress. Shoot your hips underneath his base and wrap around the 1Leg X, finishing him with either the 1-2-3 sweep or the Ankle Pick Sweep.
