Sean Roberts (Team Ralph Gracie)

Here is a video of one of my sons' jujitsu instructors in a competition. Sean is the one with the blue gi and short hair. You may notice that he often begins by getting his opponent in a "full guard", which means the legs are locked around the opponent's waist. From there he is able to do all sorts of things. My favorite move was toward the end, around 4:43 in, where he jumps up like a cobra, wraps his opponent around the neck with his legs, and performs a triangle choke from on top. Not something we see in the kid's class. I was surprised to learn his age. Feel free to take a guess at how old he is.
