Artemis BJJ (MYGYM Bristol), Can Sönmez, Bristol, UK - 28/10/2015
I went with the bump and frame to butterfly, a relatively basic technique tonight. This isn't an option I often go for, but I do regularly use some of the principles, as quite often I'll end up trying to dig my knee through.
First of all you need to get their hips in range. It is more difficult to land this escape if they're still upright, although in that case you would probably go for something else. Knock them forward with a bump, pressing your knee into their back. As soon as they're horizontal, frame your arms into their hips and do a powerful bridge (heels as close to your bum as possible, pushing high, on your toes).
Stiff arm into both their hips, so that when you drop your hips back down, the space you created from your bridge is still there. Bring both your knees through that gap: having been balanced on your arms, they are now balanced on your shins. You can then kick forward with both legs, using the momentum to also sit up. This should put you directly into butterfly guard, where you can immediately sweep them.
If they are still upright, you can still do it sloppily by jamming as much of your knees as you can into the space you create. It ends up being one or one and a half knees, knocking them off to the side at best. Still, that can work too, and will almost certainly be better than staying stuck under mount. It can also potentially give you a chance at moving into x-guard or something like that, circling your outside around to press your foot into their hip. A double-shin sweep could work from here too.
Teaching Notes: This technique does allegedly work with much bigger opponents too, but I played it safe anyway, being careful to pair people up based on size. The idea is to brace their weight with your arms, then transferring it to your shins/knees, then kick forward into butterfly. Most likely it's perfectly safe once people get experienced with the technique: starting out, it seems sensible to avoid any big weight discrepancies!
I put in a butterfly sweep too, given that the basic bump to butterfly is mechanically very simple. I'm not sure if that meant there was too much, but I'll check on feedback. Previously I've combined the bump with a technical mount escape, so that might work better. I can just go with the simple shoving your knee in option from under technical mount, as that fits in well with the principle of the bump to butterfly. It's how I did it last time, so worth giving another go (unless the feedback I get is that they love combining the bump to butterfly with a sweep).
