This is yet another technique I've been trying out from the Paul Schreiner Precise Pressure Passing app I'm reviewing. The idea is essentially to sit on their legs: Schreiner sits right on the ankles. You also grab their collars, staying low and moving with them if they try to free a leg. That collar grip is important, as it keeps you tight, preventing them getting the space to free a leg and recover guard. Your goal is to gradually bring one of their knees past the centre line of your chest (e.g., guiding it across with your elbow). Once it drifts over there, you can collapse their knees to the ground with all your weight on top.
Sprawl over their legs, pressing your chest into the middle of their thigh to pin their legs to the mat. Moving around behind, using your hand to maintain the pin on the legs, then switch to side control. Alternatively, you can swipe your leg over their pinned leg, pressing your shin into the lower part of their leg. That again traps their legs in place, giving you the opportunity to move around behind them to side control with relative impunity.
Teaching Notes: Again, main thing is grab those collars and pull them in tight. When you push the legs across, you're getting those knees past your chest, not lower down (though I guess that could work, not something I've tried yet ;D). In terms of pinning the legs, I went mainly with the hands, but it would be worth emphasising the shin trap too. Some people had difficulty spreading their knees far enough to sit comfortably on the shins. If you have flexibility issues in that area, a good alternative could be sitting more on their insteps, with their knees higher in the air. You can then do more of a kneeling crouch type position, making sure you don't actually kneel on the ground (as that takes all the weight off them and onto the mats instead).
