Professor Teco Shinzato and Leandro Silvestre (who I have never heard of before but don't care) put a series of short videos of his half guard game up on youtube. They've been around for a while but I never paid much attention since I wasn't working on half guard, much less the super deep kind he shows. But now that I've gotten a taste, I can see how it'd work.
I'm reposting the videos here for reference. I'm writing short descriptions because that's how I learn best from video: breaking it down and explaining what I see. I'll spot new details as I rewatch it over and over and try to figure out how to explain it.
- Starts with an underhook and grabbing the belt with his left hand. Ankles crossed on the outside of the leg.
- With his left arm, he reach through their legs and under their thigh, up by the hips instead of by the knee.
- Opens his legs, keeping his right foot on the back of their calf. Left leg steps out on the mat.
- Left hand moves from the belt down to grab the pants at the knee.
- Swings his legs and rocks his hips to the opposite side, carrying their leg on himself.
- Right arm comes down and hugs the trapped leg to his chest.
- Grabs their arm with both hands and traps it against their own thigh.
- Steps on the mat and rocks his hips back the other way.
- Rolls up on top and comes to his knees.
- From this angle, I see he's starting from a framing or double paw position, to keep the crossface off before he gets the underhook.
- Same sequence as before to get deep under the single leg. Traps the arm the same way.
- He doesn't explain it, but from looking, I think he rocks like he wants to go for the first sweep but they don't have their weight going that way. So he rock back and keeps trying to come out the other way and knocks them over.
- From this angle, I can see several things more clearly. He is putting his knee into their hip at the start to keep space. He does have a double paw. He takes the knee off the hip and his leg to give him momentum to sit up and bury his head against their chest as he gets the underhook. He gets his elbow high.
- Same entry to deep half guard under the single leg.
- He reaches down with his left hand and grabs their ankle and pulls it to him.
- He switches and underhooks the leg and keeps pulling it to him.
- His left calf goes on top of their thigh.
- He swings his legs down and pulls their leg to knock them back and rock up to get on top.
- Same starting position, same entry to deep half guard.
- Only this time, instead of hugging the trapped leg, he keeps his right hand reaching up through the legs and grabs the fabric on their back.
- His left hand swims under their knee as he opens his legs.
- With both arms under their legs, he turns into them as he comes to his knees and immediately passes guard.
- Same standard beginning and entry.
- Reaches behind his left knee with his left hand and grabs their pants.
- Opens his legs and lifts the knee in the air.
- Turn his hips to the front and swivels his knee under their leg.
- Keeps pressure on their shin with his left calf.
- Left hand grabs the fabric around their upper arm.
- Right leg lifts them, left leg knocks out their leg, right hand punches them up and left hands pulls their arm. Big circular motion with every limb.
- Comes on top and immediate gets out of half guard to pass.
- The usual.
- Once in deep, he brings his right hook under their ankle. His left ankle stays on top of their foot.
- He takes his left foot off theirs and puts it on the ground.
- He lifts their leg with his butterfly hook and passes it to the front.
- He drops them away from himself as he twists out to his knees.
- He keeps a wide base and hugs their leg to secure a top position.
What I find most interesting about these clips is how they're using the rocking motion of their hips to rotate the leg so they can get deep. They aren't trying to pull the guy on top of themselves. He naturally comes on top as they go deep and swing underneath him.
