Check out the half-guard pass at the end of this short video sample from Marcelo Garcia. The full piece is a spider guard pass, which is certainly worthwhile. But because I'm working against a lot of half-guards in class, I'm especially interested in half-guard passes.
Here are the relevant steps:
Underhook with the same side as the trapped leg.
Overhook the other arm and bring it to the side.
--This will keep him from blocking your pass.
Keep your hip as low as possible.
--This will bring his knee down.
Put your free foot on his knee.
--His knee should be on the ground.
Push your foot against his knee as you pull your other leg free.
Slide the trapped leg under your body.
Switch your hips from down to up.
Sit up into a scarf hold.
--You will have the overhooked arm trapped.
By the way, best of luck to Gracie Barra brown belt Cindy Hales, who is competing at Grapplers Quest this weekend in Las Vegas. She's part of an eight-woman lightweight tournament and is scheduled to face off against Jean Jacques Machado fighter, Jeanette Portocarrero.
According to this preview from On the Mat Portocarrero is also a "relative newcomer" to Grapplers Quest. Jeanette competed as a purple belt in 2004.
Anyway, may any of the numerous submissions Cindy has inflicted upon her sparring partners at Gracie Barra Seattle (my elbow and ankle included) find the limbs and necks of her opponents this weekend in Sin City!
