Single Leg from Butterfly Guard

Single Leg from Butterfly Guard is a transition between related positions built around a handful of repeatable controls. Bottom player is in butterfly guard with the opponent posted on both knees, hiding their legs and looking for an underhook or body lock. Another common starting shape: bottom player is in butterfly with one of the opponent's legs isolated or accessible to the inside. The ideas that hold it together are frames over grips when the opponent is kneeling, elevation creates the path to leg entanglements, and foot in hip and foot behind knee are non-negotiable.

The single leg chain is a sequence of small controls, not one athletic burst. Use butterfly hook to elevate rather than relying on grip strength. Frame on the shoulder or biceps to keep the opponent from collapsing forward. As the opponent lifts, slide the body underneath and thread the legs into single leg X. Isolate the target leg by clearing the opposite foot. Insert the inside foot in the hip and the outside foot behind the knee. Grip the foot or pant cuff with both hands. Off-balance forward by extending the legs and pulling the foot. Elevate one butterfly hook to lift top player onto a single leg. Bottom player has elevated the opponent and inserted a single leg X configuration, controlling one leg with both legs wrapped around it.

Later in the single leg, sLX is a leverage position, not a strength one, hook elevation, and leg entanglement entry tend to decide whether the position stays on track. Watch for these mistakes: Chasing an underhook that the opponent uses to body lock and flatten you. Lifting before the frame is established so the opponent settles back down. Entering SLX without securing both feet correctly. Leaving the trapped leg's foot loose. The high-percentage version of single leg from butterfly guard is the one you can still chain when the next position is contested.
