Artemis BJJ (MYGYM Bristol), Can Sönmez, Bristol, UK - 30/10/2016
Starting from the side ride, dig your near knee next to their hip. You're aiming to shove that as deep as you can behind their arm. Once it is in deep, flare the knee out towards you, which should make their arm available for your other heel to hook. Drag it back over your other leg and use your legs to lock that arm in place. At this point, you've already got a bunch of attacks available to you, but we want to get them face-up.
You'll probably be grabbing their wrist, their bicep, their sleeve or something else with your arm on the near side. With your other arm, reach under their far armpit and grab their shoulder. They could trap your elbow and try to roll you at this point, but that puts you where you want to be anyway. In the likely event they aren't foolish enough to do that, you have a few entries to the face-up crucifix available to you.
The one I prefer is from that Jacobs seminar. Walk your feet back towards their bum, staying low and tight. Keep walking until you roll over their leg, putting them face-up. As you move into that position, make sure that your far arm is hooking back behind your head: otherwise, they can wriggle their arm free without too much trouble, enabling them to turn and escape. Alternatively, thread your arm inside theirs and grab the meat of their hand, twisting it outwards. That grip makes it hard for them to wriggle their hand free.
You don't want their weight too far on top of you, as again that can help them escape: if that happens, shrimp your hips slightly to bring them down again. However, you don't want them to slip too far down to the mat, as there's another escape they can do in that situation. So, if they're too far down, scoop under them to prevent that escape.
You're now ready for the choke, which is nice and simple. With your free arm, reach around their neck, aligning your elbow with their chin. Grab their shoulder-blade with the hand of that arm. Put your head tightly next to theirs, then squeeze your arm slightly and drive the shoulder of that arm into their head, as if you were trying to push through it. That should make them tap.
Teaching Notes: I am not a fan of nogi so don't teach it often, but with this technique I'm relatively confident. Aesopian has added some extra bits to his Mastering the Crucifix instructional, meaning I could watch a bonus nogi seminar: very useful for today. I started off with some basics on the side ride, the back take (noting not to go too horizontal), then the crucifix entry. Again, I highlighted that needed to be diagonal.
The main thing I added from Aesopian was grabbing the meat of the hand. That fits in well with what Kev had been telling me in the private lesson earlier, from guard. The same thing applies here, gripping that way makes it tough for them to get grips. It also transfers the strain from your wrist to theirs, discouraging them from trying to power out.
I'll be teaching a load more crucifix in Backvember, so will continue to draw on both Matt 'Aesopian' Kirtley and the handy material from Dave Jacobs.
