We've been working some moves to pass the knees in the last few classes. This is something for after a takedown, or maybe even after breaking open a closed guard. We worked a pass where you gripped the pants inside the knees, then stepped with your left leg so as to block his right leg with your shin. At the same time, you went into a backstep with your right leg, then switched to side control.
We also worked moving to the other side in case the guy rolls into your legs when you try to block with the shin. In this case, you step over with your right leg and do a backstep with your left leg. Slide into south-facing side control, locking the hips.
Last class (Wednesday, February 1st) we worked a pair of knee passes. One was very basic and just involved pushing the knee down and stepping through with your inside leg. Rodrigo highlighted the idea of twisting your hips as you planted the step-through foot, sort of opening your hips up to the north, to make it easier to then slip into side control.
The other technique we learned is something that really might come in handy. It's a way of passing the knees on the ground. From between the knees, you want to swim in: head into his hip, your left arm over and between his knee and his body to grab the pant cuff, your right hand under the other leg to grab the belt. Lock in this position. Then tripod up, working your left leg as close to his near leg as possible. Then backstep with your right leg--keeping your weight on his hips and your grips tight--and slide into side control.
