The Omoplata is a shoulder lock submission in Brazilian Jiu-Jitsu (BJJ) that leverages the attacker's legs and hips to hyper-rotate the opponent's shoulder joint, producing a similar effect to the Kimura lock. The term "Omoplata" derives from the Portuguese word meaning "shoulder blade," accurately reflecting the targeted joint. Historically, variations of the Omoplata existed in Judo as "ashi sankaku garami" (leg triangle entanglement) and in catch wrestling, where practitioners referred to it as a coil lock. Initially underestimated, the Omoplata gained prominence in BJJ during the 1990s, largely due to innovations by renowned competitor Nino Schembri.

The Omoplata submission targets the opponent's shoulder by forcing internal rotation of the humerus. The attacker uses their leg to entangle the opponent's arm and shoulder, driving the opponent's hand behind their lower back. Proper hip positioning is crucial; the attacker pivots approximately 90–180 degrees from their initial alignment, shifting onto one hip rather than remaining flat on their back. This angle allows the attacker to clamp their leg securely over the opponent's shoulder, creating leverage to push the joint beyond its natural range of motion.

Breaking the opponent's posture is essential, typically achieved through collar grips, overhooks, or sleeve control. Key control points include securing the opponent's arm above the elbow and managing their hips or torso to prevent escapes. To finalize the submission, the attacker sits upright, scoots their hips slightly away, and drives forward and downward with their hips, applying intense pressure to the opponent's shoulder joint.

1. Begin by breaking your opponent's posture using collar grips, overhooks, or sleeve control.
2. Pivot your hips to create an angle, swinging your leg over your opponent's shoulder and trapping their arm bent at approximately 90 degrees behind their back.
3. Immediately secure control of your opponent's hips or waist to prevent rolling or escaping.
4. Sit up promptly, scooting your hips slightly away from your opponent to increase torque.
5. Finish the submission by driving your hips forward and downward, forcing internal rotation of your opponent's shoulder joint and compelling the tap.

Practitioners frequently encounter several common errors when attempting the Omoplata:

• Remaining flat on their back without creating the necessary angle, significantly reducing leverage.
• Poor arm control, allowing the opponent's elbow to slip free and enabling escapes.
• Failing to break the opponent's posture before initiating the technique, making it easier for them to posture up or stack.
• Incorrectly controlling the opponent's leg instead of their waist or hips, compromising posture and control.
• Delaying the sit-up motion, giving the opponent space to regain posture or initiate defenses.

Effective defense against the Omoplata requires early recognition and posture management. Key defensive strategies include:

• Maintaining strong posture and quickly withdrawing the threatened arm before the lock is fully secured.
• Executing a forward roll escape, rolling in the direction of the trapped arm to relieve shoulder pressure and regain a neutral position.
• Performing a step-over or cartwheel escape by rotating toward the opponent's head and kicking the free leg over their body, potentially gaining a dominant position.
• Keeping the elbow tight and gripping your own thigh or knee to prevent the attacker from fully securing the lock.

The Omoplata is highly versatile, serving effectively as a submission, sweep, or transitional position:

• It integrates seamlessly into the triangle-armbar-omoplata submission chain, allowing fluid transitions based on the opponent's defensive reactions.
• Even if the submission attempt fails, the Omoplata frequently leads to sweeps, as opponents often roll forward to escape, enabling the attacker to follow and secure top position.
• Practitioners can transition from the Omoplata to dominant positions or alternative submissions, such as back control or armbars, when opponents defend aggressively.
• Beyond submission, the Omoplata is valued as a positional control tool, effectively managing the opponent's posture and movement.

The Omoplata's effectiveness varies between gi and no-gi grappling contexts:

Gi Grappling

In gi grappling, practitioners benefit from additional grip options such as collar, sleeve, and belt grips, significantly enhancing posture control and submission finishing. The friction provided by the gi fabric makes it more difficult for opponents to slip out.

No-Gi Grappling

In no-gi grappling, the absence of fabric grips necessitates tighter leg control, wrist or triceps grips, and active posture breaking. Due to reduced friction, opponents can escape more easily, making the Omoplata commonly utilized as a sweep or transitional position rather than a direct submission.

Despite these differences, the core mechanics remain consistent, and the Omoplata remains a viable attack in both gi and no-gi scenarios.

The Omoplata rose to prominence in Brazilian Jiu-Jitsu largely due to the innovative contributions of Nino Schembri in the 1990s. Schembri demonstrated the technique's effectiveness as both a submission and positional control tool. In modern gi competition, Clark Gracie is widely recognized for his exceptional proficiency and innovative application of the Omoplata, showcasing its continued relevance and effectiveness at the highest levels of competition.
