2 Part Technique - The Hook Lift from Butterfly aided with Double Collar Control is a versatile way to engage your opponent and disrupt his base from underneath. Let him slip off of one of your hooks, and capture his leg with an overhook if you wish to play 1Leg X, or an underhook if you prefer X-Guard. If he counters your entry by squeezing your butterfly hooks together, knock him off to the side and forcefully pull his leg down as you split his counter open. Finish the position with the 1Leg X Guard Sweep, or respectively, the Unbalance Sweep from X-Guard.
