Went over to a friends house after work and he showed me a few submissions :
Triangle
* From guard, get one leg inside their arms
* Throw that leg up over their shoulder
* Use other leg to push on their hip, to move across into position
- If I'm looking at their ear, I'm in the right spot
* Bring other leg up over instep of foot
* Close that leg up to apply pressure
- Can pull down on the leg, or their head in order to help complete the choke
RNC
* One arm goes around neck, similiar to a headlock, with hand gripping the back of opposite shoulder
* Second arm should come in elbow first so that they can't grab arm
* Transition from hand on their shoulder to your own bicep
* Squeeze arm and pull shoulders back to complete the choke.
