Another technique from Eduardo de Lima. This time it's a throw.
If my crude knowledge of wrestling terminology doesn't fail me, this is a gi version of the flying mare, at least in the initial grip and spin. A wrestler friend has now told me that the real flying mare is done more like seoi nage though.
If my memory serves me, Lucas Ezell, a brown belt from my school, used this takedown successfully several times in the 2005 Pan Am on his way to winning the purple belt division.
It's going to be hard to understand the speed and momentum of this move from pictures alone, so just try to understand that you need to use a lot of both to get your opponent to flip over like shown. This a fast move and you don't stop moving until it's done.
You need to start by getting this grip from standing. When he grabs your lapel with his right hand, cross grip his sleeve and reach under it with your left hand to grab his lapel.
Drop down and spin under their arm, like you're doing a barrel roll.
Keep spinning and rolling on your back, trying to do a full rotation. The momentum and grip on their arm and lapel will force them to flip forward.
Keep spinning and rolling as they flip over.
You should be rolling belly down as they land on their back.
Come to your knees. You've still got control of his arm and lapel from the start of the move. From here you'll need to drive into him and establish side control.
I hope that I've given you enough to spin about today.
