To me, if you are in a pin and exposed to being genuinely hurt and you insist on thrashing about, Uncle Darwin is smiling down upon you..... The pin is a pause for both sides to take note of the current situation and respond accordingly. The graciousness of the pause should not be mistaken for weakness or strength.
Nor with delusion about what one can really do if the pinned fights back.
Do you remember Amdur's story about what he thougt he could do with his vital points striking against his judo friend?
Sometimes Darwin is smiling but sometimes Pavlov is the one who is smiling.
