Introduction to the Z-Lock
The Z-lock is a submission technique accessible from the diagonal ashi position. Unlike most leg locks that require both hands to execute the submission, the Z-lock uses only one arm, leaving the other free to control the opponent's secondary leg.
Why the Z-Lock is Effective
The Z-lock's primary advantage lies in its one-handed submission mechanism, which preserves one arm for secondary leg control. By controlling both of the opponent's legs simultaneously, the instructor creates an inescapable position that makes submission nearly inevitable.
Understanding Cross-Ashi Position
The cross-ashi is a foundational control position where both feet are placed inside the opponent's legs, with the primary leg positioned across the instructor's centerline. From this position, the instructor can transition to the diagonal ashi by adjusting the placement of the primary leg outside the hips.
The Over-Under Grip Transition
The over-under grip sequence transitions the instructor from cross-ashi to diagonal ashi through a systematic re-gripping pattern. The instructor controls the secondary leg by placing their forearm over the opponent's thigh while gripping the shin, positioning their shoulder and chest as an obstacle to knee retraction.
Executing the Grip Sequence
The transition involves securing the initial grip, tying everything up by gripping the far shoulder, then systematically re-gripping and rotating to establish the diagonal ashi position. Maintaining tightness throughout prevents escape opportunities and ensures control before advancing to the submission.
Key Positioning Differences
The critical distinction between cross-ashi and diagonal ashi is the location of the primary leg relative to the hips: inside for cross-ashi and outside for diagonal ashi. This positional adjustment grants access to the Z-lock submission while maintaining superior control of both legs.
Control Before Submission
Maintaining patience and maximizing positional control before executing the submission is essential, similar to prioritizing control in mount position. If the opponent weakens the instructor's control during the transition, returning to the dominant control position should take priority over advancing to the submission.

I stole this technique from Bobby Sandhu who stole it from Pierre Olivier Leclerc who apparently stole it from a blue belt at Tristar. It's easily my favorite way to get into the diagonal ashi which is usually called the Z lock position.
