Ok, here’s the techniques that were drilled waaay back in BJJ Class 94. Hope I still remember the details…
Nogi starts off in guard, pulling on Boarder’s sleeves, his knees controlling Boarder’s elbows, and his feet on Boarder’s hips.
Nogi brings his left arm up and out to have Boarder’s arm betweeen his legs and hooks his right leg against Boarder’s body near the armpit.
Nogi brings up his right leg tight against Boarder’s body under Boarder’s arm. Nogi pivots on his back, with the help of his left leg pushing off of Boarder’s hip, but (strangely) Nogi’s right leg helps a great deal with the pivoting…
… and the pivoting gets Nogi to position his left leg to position for the armbar…
…but it the technique is loose and Boarder is able to pull his arm out. Boarder thinks he’s safe, but he left his other arm between Nogi’s legs, leaving him vulnerable to an omoplata or …. (let’s call this point B)
Nogi puts on the finishing touches and taps Boarder with a triangle.
