Single Leg from Single-Leg X Guard

Single Leg from Single-Leg X Guard is a sweep that puts the bottom player on top built around a handful of repeatable controls. Single leg X with the trapped leg pinned to the chest and one foot in the hip, the other shin behind the standing knee. Another common starting shape: the bottom player is engaging from open guard or butterfly and the opponent posts on a knee or steps in within reach. It is worth attempting once comfortable with: Butterfly to single leg X transition. The ideas that hold it together are off-balance first, then thread the legs, ankle grip closes the trap, and grip retention.

The single leg chain is a sequence of small controls, not one athletic burst. Extend the foot in the hip while pulling the trapped foot down toward the mat. Use the shin behind the knee to kick the standing leg off line. Come up to the knee and finish a single leg or pass. Slide the bottom leg behind the opponent's knee while loading the top hook. Secure the ankle grip before extending the legs. Tuck the head and shoulders under the opponent's hip to anchor the entry. Use the collar pull and sleeve grip to keep the partner posted high. Switch the trapped leg out and replace it under the partner's hamstring. Top player has been collapsed backward; bottom player rises to a stable top position with the leg still controlled.

Later in the single leg, leg entry, standing leg is light and attackable, and catch timing during weight transitions tend to decide whether the position stays on track. Watch for these mistakes: Trying to enter without first elevating or off-balancing the opponent. Sliding under without ankle control, allowing easy escape. Releasing the collar grip during the leg switch and losing posture control. Failing to off-balance forward so the partner just walks the leg out. The high-percentage version of single leg from single-leg x guard is the one you can still chain when the top player posts or re-bases.
