The omoplata armlock is a very interesting move to use or see used. It is in essence it is a kimura lock but instead of applying pressure with one’s hands the pressure is applied using the legs and body. This move is slightly more difficult to set up and complete than your average submission. However its effectiveness is almost unmatched if one can land it successfully.
In recent years more and more people have been using the omoplata and variations of it like the gogoplata and the monoplata. this move has grown and become very dynamic with multiple submissions stemming from its set up.
Submission or Sweep
One big aspect of the omoplata is its dual purpose use as a sweep or a submission. Since the move is most commonly used from the full guard it is a great way to sweep one’s opponent even if the move cannot be completed as a submission
One way that this move is commonly used as a sweep is in transition from a triangle choke. Durring a triangle choke a common defense is to wrap the trapped arm behind the attacker’s leg. Unluckily for him this then puts him in the perfect position for an omoplata.
If a submission is the desired endgame there are plenty that one can complete from the setup of the omoplata. This makes the omoplata a hard move to defend against because there is not one set way to perform the submission but many many variations
The most common way to end it is the kimura style lock. For this submission the opponents arm ends up being chicken winged via your legs. This puts incredible pressure on the shoulder to force the tap out
Another submission that can be completed is a wristlock. Once on top of the opponent, instead of using your body to put pressure on the shoulder, the opponent is held down easily from the position that is set up and a wristlock can be easily applied.Also a footlock can be completed from this position as well. Commonly an opponent will try and roll into you to relieve pressure from his shoulder. As he rolls his legs and feet become readily available for attack and a fotlock can be applied. In addition to this as the opponent rolls the arm is still entangled and an armbar can be used.
Defending the attack
There are a few ways to defend against this attack. One is a preemptive defense and as soon as you feel the arm being isolated for the omoplata you need to start rotating towards the isolated arm side. From there the opponent cannot complete their move and will have to change strategies
If the opponent has already isolated the arm and flipped on top of you there is the rolling defense. Although very cool looking and fun to do, if this defense needs to be used top position is given up and it means the opponent almost had you in the submission.
Or there is the Turtle Roll defense
