When you're being pinned, at what point should you turn your face, so that you can't see tori/nage, and expose the back of your head?
I'd say: when tori has you secured...? - So that you stay 'live' until that point, and can take advantage of any openings that are presented...?
Am I wrong?
What are the opinions on this?
I think you should turn your head at the beginning of the pin. Better to get punched in the back of the head than in the face. You don't need to physically see an opening to take advantage of it.
