Last Saturday, Strikeforce champion Ronda Rousey again stunned the crowd with an indefensible armbar, this time over Sarah Kaufman.

For two of Ronda’s training partners, black belts Eddie Bravo and Alan Belcher, one of the finest aspects of the move was the streamlined transition to armbar when the mounted opponent gave up her back.

“There are guys who are really good at defending the back … When you’re on someone’s back they have their hands and their chin to defend with,” says Bravo, explaining why he prefers being positioned sideways in what he calls the “spider web”, the armbar setup Ronda Rousey went to rather than sinking hooks for back control.
