Here’s the technique we went over in BJJ Class 93. I’ve been doing this sweep for a while now, but have missed a few key details…
Nogi starts with Boarder in his closed guard.
Nogi hipscapes backward and rotates a little to the side. He positions his left leg flat on the mat against Boarders leg. Nogi’s right knee is by Boarder’s chest, with his leg pressed against Boarder’s upper body. Note that Nogi hooks his right foot on Boarder’s body. Let’s call this part Step 3.
Nogi sits up, bringing his upper body closer to Boarder. This is the step I always forget. Against lighter guys, it doesn’t matter. Against heavier or more skilled guys, this is crucial to getting the sweep.
Keeping his arms tight, Nogi leans back thus bringing Boarder with him – this upsets Boarder’s base, and makes the rest of the sweep much easier to perform.
With Boarder off-base, Nogi does the rest of the sweep as usual. He pulls Boarder with his arms, scissors his legs together, kicking his right leg up and over.
… and push down on it, sliding Boarder’s leg back and removing his base. This can also be combined with the little sit-up, so as to help with the sweep better (arms moved out of the way so you can see the foot/knee).
