Entering Leg Weave from half guard threads an arm through the leg gap to control the lower thigh or knee and fold the knee shield toward the other leg.
The top passer begins in Half Guard, facing a knee shield or linked leg frame. The weaving limb is the arm. Securing that control is the entry checkpoint; a pass is complete only after the hips and remaining leg hooks are cleared.
Thread the arm through the available leg gap and connect to the lower thigh or knee. Use aligned shoulder pressure and chest pressure to bring the knees together without twisting the knee joint. Avoid leaving the weaving arm extended where the bottom player can sit up into a kimura.
Move through available space with a stable base. Stop and release any trapped neck, shoulder or knee before changing direction; do not force a roll or stack to preserve the route.

Playing as Attacker
Key Principles
-
Weave the arm: Thread the arm through the available leg gap and connect to the lower thigh or knee.
-
Manage the knee shield: Use aligned shoulder pressure and chest pressure to bring the knees together without twisting the knee joint.
-
Keep the elbow protected: Avoid leaving the weaving arm extended where the bottom player can sit up into a kimura.
-
Maintain an outside base: Move the hips and feet without collapsing all weight over the woven arm.
-
Clear the legs before settling: Remove the remaining foot or half-guard hook before establishing side control.
-
Follow the hips: If the bottom player turns or inserts a frame, keep control of distance and reset the pass rather than forcing a fixed angle.

Common Mistakes
-
Skipping the checkpoint: weave the arm
- Consequence: The intended control is not established before the next movement; the missing requirement is: Thread the arm through the available leg gap and connect to the lower thigh or knee.

Playing as Defender
Key Principles
-
Recognize the arm weave: The passer’s arm connecting your legs is the relevant control, not a leg threaded across your hip.
-
Keep the shield supported: Maintain a useful knee angle and upper-body frame before the passer folds the legs together.
-
Recover inside space: Move the hips and pummel the knee back between the bodies while the weave is still loose.
-
Deny upper-body collapse: Prevent the passer from flattening your shoulders while controlling the legs.
-
Use an available underhook: An underhook can help you face the passer and rebuild half guard when the shoulder line is not already pinned.
-
Move the whole leg: Do not wrench a knee out of a fixed weave; create room with the hips and frames first.
Recognition Cues
-
The top passer begins in Half Guard, facing a knee shield or linked leg frame.
-
Use aligned shoulder pressure and chest pressure to bring the knees together without twisting the knee joint.
-
Move the hips and feet without collapsing all weight over the woven arm.
Defensive Options
-
The passer’s arm connecting your legs is the relevant control, not a leg threaded across your hip. - When: Before the next connection or finishing pressure is established; stop if the neck or limb is already loaded.
-
Maintain a useful knee angle and upper-body frame before the passer folds the legs together. - When: Before the next connection or finishing pressure is established; stop if the neck or limb is already loaded.

Position Integration
The top passer begins in Half Guard, facing a knee shield or linked leg frame. The weaving limb is the arm. Securing that control is the entry checkpoint; a pass is complete only after the hips and remaining leg hooks are cleared. A destination is established by its actual body configuration, not by completing an isolated grip or by the name of the route.
