Professor Edson Oliveira describes the transition from a cross collar choke attempt into a high-pressure S-mount armbar when the opponent successfully defends the neck. If the opponent frames to block the second hand, Edson shifts the weight forward and rotates the hips to slide one knee high behind the head while the other leg wedges tightly under the armpit. By leaning forward and basing the hands on the mat, Edson prevents the opponent from bridging or rolling backward. The sequence concludes by isolating the arm and working it across the mid line while maintaining a heavy chest to arm connection, eventually allowing the leg to pass over the face with the knees pinched tightly to secure the armbar submission.
