Professor Andre Gois teaches how to escape from the 50/50 guard using the berimbolo. The opponent has Andre in the 50/50 guard and Andre starts to defend by under hooking the opponents legs gripping the top of the knee. He comes up and uses his arms to push the opponents legs away so he can slide his knee out. Andre now switches the grips to the ankle and reaches for the pants on the side. He then goes for the berimbolo to escape from the 50/50. From here, depending on the opponent's reaction, he can go to the site control position or take the back control.
