More good judo to start the week off. I arrived a little late (again), but I was able to catch some nice trips off of a blocked seoinage type throw. The first trip was just an inside step where you hook your forward foot behind the guy's ankle after turning your body to attempt the hip/shoulder throw. The second trip was specifically off a blocked ippon seoinage, and resembled the ko uchi gari throw.
Actually both trips were ko ouchi gari, I think, with the second being a variation where you grab the leg with the ippon/hooking arm, step behind that leg, and use your shoulder pressure and body weight to drive the guy to the mat.
Both takedown ended up inside the guard, which Prof. Carlos showed us how to step out of and then, switching base and getting a grip under the head, move into half guard or even directly to the pass.
On the ground, we worked on side control transitions to mount, including a knee on belly option. Prof. Carlos likes the Renzo-style, tight side control, with the over/under gable grip, the "shoulder of justice", and both knees in tight against the guy's body. One check to see if you are tight enough is whether your north knee and your north elbow are connecting. If they are, then your side control is solid and ready to go.
The main ideas here were strategies to open up the guy's body for the knee. Specifically, we use the north knee to open up the near-side elbow, which opens up the body for the south knee to slide in. To get from knee on belly to full mount, open up the elbow with your under/over body gable grip and bring your knee to the mat.
Trained with Jessee and Glen to finish things up. Jesse continues to expose my vulnerabilities with the deep half, especially the same triangle that Sauleh, Rodrigo and Prof. Christiano have all attacked me with successfully. I'm going to e-mail Jeff Glover tonight and see if he has any tips on how to avoid the triangle when attacking with his #1 sweeep. But right now I'm thinking of shelving it since it is just leading to trouble whenever I train with someone my level or better. For now, a better option may be to use the deep half as a transition opportunity to switch back to the more familiar and time-tested ground of the regular half.
