So, in ne waza randori, I've been working a lot on submissions from guard. As a result I have been pulling guard from the knees. Problem is, half the time I get passed on the way in, because I've been thinking of the guard pull as merely setting up the randori, whereas my partners, understandably, see it as an opportunity to pin me.
Any tips on this combat-useless and totally auxiliary skill? I'd rather just pull it than tell them I'm going to start in guard.
