First thing I wanted to cover was posture. Stay upright, with your head up. Curving your back slightly, arching it like a cat (so, convex rather than concave), can help too. Don't let them bend your arms: keep at least one of them stiff into their hip. It is important to control their hips, as they need to angle off to attack effectively (though there are other methods, like Christian Graugart's 'samurai sword' grip, where both arms are near the chest). Your other hand is ready to push them down if they attempt to raise their torso towards you, or more typically, gripping both collars and keeping their back on the mat.
Be aware that you don't want to extend that arm too far or they can break your posture: it's also likely that they will primarily be looking to dislodge your arm and gain control of it, so be ready to disengage and then quickly re-engage the grip. Having said that, there are numerous other ways of posturing up, so it's good to experiment.
For a strong base, widen your knees, sitting on your heels. Alternatively, you could try squeezing your knees to their hips to stop them moving, but that will result in a less sturdy base. Make sure you do not put your elbows on the outside of their legs: keep them inside, or they can start kicking up into your armpit for triangles, armbars, flower sweeps etc.
A key detail is to come up on your toes. This will feel uncomfortable at first, but it provides you with much better base than having your insteps flat on the floor. With your toes up, you can resist their attempts to pull you around. It also enables you to drive forward and improves your mobility.
Another way they'll be looking to disrupt your base is to angle their hips away. To prevent that, you can simply follow them, making sure you keep squaring back up so they don't have that attacking angle anymore. You could also try caging their hips by squeezing your knees together, but that can result in a less stable base.
In order to attack, they are going to want to disrupt your base and break your posture down. The first way they'll probably do that is to establish a strong grip, on your sleeve and collar. You don't want that, so try to strip any grips before beginning your pass. Not to say that it's impossible to pass if they've got grips, but you'll find it easier if they don't.
If they grab your collar, you can use both of your hands to grab either side of that sleeve or wrist. Push it forcefully away from you, while simultaneously leaning back slightly. Another option is to put both your hands on their gripping arm, trapping it to their torso. Posture up forcefully to break the grip. Alternatively, you could try simply re-establishing your grips on their collar and hip over the top of their arms, meaning you can press your arms into theirs. That way, it's possible to use arm pressure to loosen their grips to the point they become less effective.
The basic method of opening from the knees starts by setting up your own grips, grabbing both collars with one hand, by their chest, your other hand by their hip. Dónal has a handy tip about twisting up those two collars, rolling them over each other so that there is no slack when you grip, though that may sometimes be tough to secure.
Also try to jam your palm or fist into their sternum to lock it in place. Regarding your hand on the hip, measure your gripping position by bringing your elbow back to their knee. Once your elbow gets to their knee, grab whatever trouser material is then under your hand, pressing your weight through that hand into the mat to try and pin their hips.
From there, get your knee underneath their butt cheek, meaning they are slightly raised up onto your leg. Your other knee slides out to the side, so you're now making a right angle with your two knees. Still keeping your back curved, slowly wriggle backwards, shifting your sideways knee back and continuing to wriggle until you can pop open their ankles. As soon as you do, immediately shove their leg to the mat with your elbow and/or hand, then begin your pass.
Saulo's version, as per that earlier picture, has the knee off to the side with the leg stretched out, using a sort of dip rather than relying on scooting back. As ever in jiu jitsu, there are numerous variations: you can reach your destination following a multitude of paths. Tonight, I went with the knee cut, starting from a low position rather than the standing start I normally go from.
Teaching Notes: I should add that break as a drill, to get people more used to it. With the knee slide, I taught a very low one. I think it's best to pin with the leg first, in terms of the order. This also relates to what Neil Owen taught, in his sequence: I'll be teaching the rest of it too.
In sparring, when sweeping I also forget to nab the hand, probably because I don't like gripping sleeves. That means I need to get people at underhooking the arm. It was also great to spar with Tad, as it's been a long time. I tried to various grips, trying to be careful of my fingers, eventually getting caught in a triangle. I went for the triangle defence where you grab the knee and drive, which gave me enough space, but then got armbarred instead. Worth remembering about trailing arms. ;)
