Professor Lucas Lepri teaches how to prevent the opponent from reaching the deep half guard. Lucas is in the opponent’s half guard and is getting ready to pass. The opponent attempts to go for the deep half guard but Lucas defends. Lucas moves his top leg up and slightly turns his hips as he raises and points out his other knee. He uses his top hand to block the opponent on the pants or on the hip. He now under hooks the opponent and changes his base with his legs. From here, Lucas now cross faces the opponent and passes to the side control.
