In this week's Master's Class, our Brazilian Jiu-Jitsu blue and white belts worked on fundamental skills, as well as a new method for the infamous triangle choke. Grandmaster John Taube demonstrated his approach towards a successful triangle choke by clearing the arm in a way that prevents the opponent from escaping the move. "When you make an effort to move the arm, trap it instead of moving it," he says, showing his students how clamping down on the arm with both legs makes the transition much easier. "There's no space for them to get their arm through." With a shift resembling the popular scissor sweep, Taube manages to prevent the usual space seen in the transition and moves freely to the next step, as though effortless.
