Foundation Posture Drill

Begin in closed guard position and practice the foundational posture movement. The practitioner alternates postured positions from low to high, shifting weight side to side in a controlled, deliberate manner. This drill develops the base stability required for guard passing.

Hand and Elbow Placement

Maintain strict elbow positioning throughout the technique, keeping elbows on the outside of the body at all times. Avoid collapsing elbows inward, which creates vulnerability to arm attacks. Proper hand placement on the belt or pants provides control without compromising defensive structure.

Head Position and Postural Integrity

Keep the head high and eyes forward—never drop the chin to look down. Maintain an upright posture by looking over an imaginary fence rather than folding forward. This positioning protects against submission attacks while allowing visual awareness of opponent movement.

Breaking the Guard and Creating Space

Execute the guard break by postured up with the spine neutral and driving one knee toward center to create separation. This action generates a critical gap between the practitioner's hips and the opponent's legs. Either method—knee break or posture break—achieves the same result of opening guard control.

The Boogie Board Position

Transition to the low, wide stance known as boogie board position after breaking the guard. From this position, the practitioner prevents guard re-closure and controls the opponent's ability to execute advanced guard techniques. The low posture provides stability while limiting the opponent's attacking options.

Double Underhook Setup

Insert both arms underneath the opponent's legs with underhooks, positioning one arm over the lap and the other inside the legs. Maintain external elbow positioning to prevent arm attacks. This double underhook configuration creates mechanical advantage for the pass.

Waist Control and Drive

Secure both hands on the opponent's waist or belt, using the belt knot as a reference point for control. Drive the opponent toward the practitioner's body while maintaining knee pressure on the inside leg. This controlled drive initiates the final passing sequence.

Knee Support and Arm Protection

Keep the inside leg actively supporting the underhooking arm to prevent the opponent from pushing the elbow upward and recovering guard. The leg acts as a structural brace, allowing the practitioner to maintain pressure and control. This coordination prevents advanced guard players from escaping.

The Final Pass Pivot

Drive forward by pivoting on the big toe while keeping the heel grounded, shifting body weight to clear the opponent's legs. Drop the hip in a controlled sprawl motion to allow the legs to pass in front of the opponent's body. Complete the pass by establishing side control with full weight distribution.
