I recently posted several instructional videos for the barataplata. Since then, I have been using the technique with some success (and from various positions). Indeed, I am convinced that despite the attention the innovative shoulder lock by Freitas has received, people have underestimated just how effective the technique can be. I already think it is a better submission from open or closed guard than more traditional submissions like the arm bar, triangle, and omoplata. Once you figure out the basic concepts and principles involved and what I am calling the "base camp" position--which enables you to transition to the barataplata, wrist lock, straight arm lock, modified omoplata, bicep slicer, and arm bar--it is a wickedly versatile technique. I hope to make my first instructional video soon (which will surely be dismissed because I am a lowly purple belt...but I digress). For now, I wanted to share some videos that shed additional light on not just the barataplata, but shoulder locks more generally.
First up, a video by Kesting wherein he explains the key differences between the barataplata, the monoplata, and the omoplata. Second, there are two videos about the reverse omoplata (AKA the samboplata). Third, a former coach of mine from Gracie Barra (Carlisle, PA) shows how to transition from the barataplata "base camp" position to a bicep slicer. Finally, the folks over at Great Grappling show a nice transition from the traditional arm bar position to a shoulder lock. Needless to say, I am excited to add these techniques and details to my grappling tool kit! Hopefully, you find success using these techniques as well.
