Monday night Mamazinho showed us more moves out of what I've been calling "SWAT Team." SWAT Team basically involves doing a "hip split" (a neologism defined by a neologism, I admit ...) around the lead leg as the base of a number of different sweeps.
One of the main ones is the one that Rodrigo showed, out of a lying back Cobra guard. The guy comes up on a knee. You do a hip split and hook that lead leg with your leg (right on right, left on left). I need to ask him what the hand/arm work is, but it's a hip split move.
There's also the Marcelo Garcia single leg, where you use the opposite side arm (opposite of the leg that is forward in the hip split) and turn into them, taking them down from behind as you stand up.
Mamazinho showed more variations. The main one has you push off the hip with the other leg, and then swing the hooking leg out and back before dropping it forward in the hip split. You want to have the grip on the far sleeve with one hand and wrap the guy's lead leg with the other (your outside arm).
Once you drop into the hip split, the outside sleeve grip and the wrap, you can do a couple of things. You can turn into the guy and tackle him backwards. You can switch hands and use your inside hand to grab the collar and roll him forward. If he steps forward--for example, when you try to push out on the hip--you can duck under and under hook that "step forward" leg, using that grip and the wrap grip to sweep him face forward.
Mamazinho also showed us a choke from the top. You use your trapped side/wrapped side hand to get a cross collar grip, and your other hand to push the head through, almost like a guillotine.
From there, grab the free side pants at the knee. You're going to do a forward roll, using the guy's hip as your target. Think of putting your forehead about six to twelve inches beyond his hip behind him. Like a lot of jiu jitsu, it's easier than it seems if you do it right.
