Lesson Part 3 of 3 -- Marcelo explains the importance and physical equity of initiating an attack from Seated/Butterfly Guard (Sit-Up Guard, Hooks-Guard, Inside-Hooks Guard, TK-Guard, V-Guard, et al.) with the "long" version of the Hook-Sweep (Wing-Sweep, Kuzure-Sumi-Gaeshi, Butterfly-Sweep, etc.): If your opponent floats on top of your single hook-lifting leg/foot, it is prudent to develop your ability to hold your opponent up off the ground with a taut kinetic-chain using the structure of your shin/instep connected with the opponent's inner thigh and your knee pointing upward/outward. Keeping your opponent elevated off the ground will buy you time to maneuver your free bottom-leg. If you have short legs, or even dexterous hip mobility, you can readily find a crunching transition into the "Short" Hook-Sweep; wherein, you place your free-foot on your opponent's posted-leg and kick out its base. However, if your legs are long, you will find it difficult sometimes to maneuver your bottom leg into a coiled position to deliver an accurate kick. Luckily, long-legged Butterfly-Guard players will rarely have to resort to the "Short" Hook-Sweep as an option from an elevated/floating opponent because their initial entry and extension with the Hook-Sweep entry will be more than sufficient for a successful reversal in position. Therefore, no matter what size legs you have when playing the Butterfly-Guard, you must practice entering into a strong/long Hook-Sweep as a primary sweeping attack from bottom.
