From back control, if the subject tucks the hands tightly underneath the body, which technique is used?

• A. Arm crank from back control
• B. Kimura from mount
• C. Guillotine from back
• D. Sweep to mount

Answer: (A)

In back control, when the opponent tucks the hands under the body, you shift from neck-focused finishes to an arm-based leverage: the arm crank. This finish targets the captured arm, using it as the fulcrum to twist and apply pressure at the elbow and shoulder. With the hands tucked, the neck is harder to attack, so securing the arm and creating torque on the elbow joint becomes the most reliable high-percentage finish. You position yourself to isolate one arm, control the wrist, and apply a bending/twisting motion that forces the joint to give way. The tucked hands cut off effective defenses against neck chokes, making the arm crank from back control an especially natural choice in this situation. The other options rely on neck access or top-position transitions, which aren’t feasible or as effective when the arms are tightly pressed under the body.
