The Cross-Sides Bottom equivalent of making an opponent wear all your weight is having as little of yourself on the mat as possible. I call this principle ‘Invisiblility,’ because when we’re flat, we’re easy to find by providing a level surface area for the top player. By contrast, shifting our hips even just a little changes everything, because:
A) We’re a less stable landing surface.
B) Can move more freely even though you’re carrying the same amount of weight.
C) Have a pivot point with which you can reverse top player.
D) There’s more space to recover Guard and/or go to your knees.
E) Can breathe easier! ;o)
Pedro Sauer creating a Cross-Sides Bottom scenario where only his feet and side of his core are on the mat:
Having written this post over a couple of days, I guess my overall idea of posture has evolved over the past couple years moving from:
Arms positions for survival>
Arm positions to set up escapes and reversals>
Arm positions AND hip/core positions that facilitate multiple possibilities depending on energy your partner gives you…
In accordance with the above video, Sauer is set-up to either reverse his opponent, recover Guard, OR go to his knees. Now that’s posture pal!
Back to the ‘invisibility’ idea, Henry Akins breaking down shrimp movement in terms of minimizing mat contact:
Half Guard application of this principle with Kron Gracie staying in game by keeping an angle against arguably the tightest Half-Guard Passer in Jiu-Jitsu, Marcelo Garcia @ 1:58-3:51:
