B.J. Penn calls this sweep "De La Riva Sweep While Opponent’s One Knee is in the Middle." I call it "no gi Flipside," after the move that Mamazinho showed us this spring, a move I incorporated in my Scissorhands suite.
The steps: The guy’s knee goes up. So many higher level guys start sparring this way—from Rodrigo to Stefan to Tommy and Casey. You want to put your opposite foot in the hip/abdomen. Let’s say their left knee goes up in the middle. You want to put your left foot in their hip/abdomen.
Slide your other foot (right) behind their knee that is in the middle. It’s a sort of DLR hook. What you are trying to do is trap the shin of that knee-in-the-middle leg (the position I call “Jayhawk”). The foot on your DLR hook should be close to the foot of your other leg.
Reach and get a collar tie with your left hand (the same side that has the foot in the hip/abdomen). With your right hand (the same side that has the DLR hook), reach and control either the elbow (preferable) or the wrist.
Pull the guy on you as you rock back. Once his weight is on top of you, extend your DLR hook leg and flip the guy over to the side. Follow him over to secure dominant position.
I think I almost hit this move on Wednesday night—or some variation of it. One of the things I’m trying to do is to understand the essence of sweeps, to break them down into their elementary particles, as it were. What do I need to block? What do I need to control? Where will I need to put the pressure? For example, in this sweep, you want to block the leg (DLR hook) and control the head and arm. The pressure comes from extending the leg. I feel that being able to answer these questions on the fly is key to being able to sweep with impunity—and creativity. The "unplugged" series helps me see how the some of the same key steps can be found in sweeps that otherwise look very, very different.
