Arm Triangle from Side Control

Arm Triangle from Side Control is a finishing attack built around a handful of repeatable controls. The top athlete is established in chest-to-chest side control with cross-face and underhook on the bottom player. Another common starting shape: the top player has isolated the bottom player's near arm with movement and slid into a shin-mount with the bottom player's head and arm on one side. It is worth attempting once comfortable with: Stabilize side control with cross-face and underhook frames and comfortable with: Stabilizing position after passing the guard. The ideas that hold it together are position before submission, weight distribution from the hips, not the arms, and shin mount.

The arm triangle chain is a sequence of small controls, not one athletic burst. Drive the hips low and forward to remove space and prevent the bottom player from turning in. Isolate the target limb or neck before committing to the finishing leverage. Slide into shin-mount once the knee comes out and the arm is trapped. Step over the body to thread the leg through, lock the triangle, and rotate to hantai-sankaku for the finish. Overhook the near arm and trap it against the head. Use the trapped head and arm as a steering wheel to rotate the opponent. Ride the rotation onto the back and seal the seatbelt. Threaten the kimura first to force the elbow to bend. The submission is finished with the opponent tapping or clear mechanical leverage achieved on the joint or neck.

Later in the arm triangle, head-and-arm trap, rotational steering, and seatbelt timing tend to decide whether the position stays on track. Watch for these mistakes: Lifting the hips or coming up onto the knees, which surrenders the pin. Trying to triangle without first isolating the arm with the shin-mount. Releasing the head before the seatbelt is in. Rotating without enough chest pressure and getting reversed. The high-percentage version of arm triangle from side control is the one you can still chain when the first squeeze is defended.
