He won the master 1 lightweight division and finished second at the open class.
The main weapon he used in all of his matches was a sweep from the x-guard.
We found this video where he explains how he does it.
Here’s the translation to his instructions in Portuguese:
“Playing the sit up guard, I control his belt and his arm. As I try to sweep using my hooks, he steps forward. So I change my grip from his arm to his heel. At the same time, I push him back and make him get up as I place one hook behind his knee and the other on his groin area. I put his other leg close to my shoulder. As he tries to take my hook out, I’ll push his hip back and slide the other hook down as I trip his leg and make him fall backwards. I follow his movement and come on top for the two points.”
