This is technique number two in our Cross Guard series. Please make sure to checkout the "Cross Guard Sweep to Armbar" technique before proceeding.
About the Cross Guard:
The Cross Guard is an awesome position to setup several sweeps and submissions from depending on what move your opponent makes. The top of my right foot along with my shin, block my partner/opponent from passing to his right, while the leg over his head prevents him from attempting to pass to the left and also keeps him from posturing up.
Here I am making sure that I have control of both my partner's sleeves while I shoulder walk out and put both feet on his hips.
Using the space I've just created I move my hips out to the left slightly, and put my right shin across my partner's stomach. The top of my foot is now on his right hip and I begin to swing my left leg to the outside and lift my hips.
I continue to swing my left leg all the way around my partner's head. As I do this, I'm lifting my hips and pulling his right sleeve towards my left hip.
This will pull your partner/opponent forward and will help you get your leg around your partner’s head.
We are now in the Cross Guard.
At this point, take the time to make sure the back of your left knee is snug against your partner's neck. Also make sure that you're pulling your left heel towards the floor and pulling hard on his right sleeve.
When stuck in the Cross Guard, 9 times out of 10 your partner will try to pull his arm free (his right in this case). What he doesn't know is that is exactly what I want him to do, and at the moment he pulls back hard I release my grip on his sleeve.
I immediately lift my hips high and start to move my left leg to the other side of his head (right side).
I contour the back of my left knee to the side of his neck, simultaneously I begin stretching my head/body to the left and start to feed his left sleeve across to my left hand.
After creating the proper angle by stretching my head/body out to my left, I reach up and grab my shin with my right hand. Make sure you pull down on your shin to keep your partner/opponent from posturing up before you can secure the triangle.
While continuing to hold my shin, I lift my hips and lock the triangle (no pic of this step, sorry). I've also made sure to pull my partner's left arm across my body. There are many different ways to finish the triangle, I can pull my partner's head down with both hands, I can hug my knee, etc. Whichever you choose, make sure to pinch your knees together and lift your hips!
