Professor Frederico Silva teaches how to defend from a triangle choke attempt. Frederico is in the opponent's closed guard and the opponent brings his leg over to try and set up the triangle. Frederico immediately keeps his elbow pointing out and grips the same side collar to prevent the opponent from crossing the arm. He now stands up and brings his knee to the same side he had the collar grip. The knee is then used to push on the opponent as Frederico then postures up and escapes. From here, Frederico then transitions to the side control position.
