How you can fell an opponent even when both your hands have been locked

How would you lock your opponent’s both arms? You can achieve this with the "Bottom Capture Hand" technique. And if he locks your both arms and attempts to fell you, how would you counter? You can fell him instead, even when both your arms have been locked! How would you strike your opponents without fear of being counter-struck by them? "Outward Grip" and "Top Contain Hand" are two of such techniques, which are excellent against fast opponents, like Boxers.
