Newish blue belt here. We have been drilling different sweeps and subs from DLR for the past month or so. I feel like I understand what's being taught and enjoy drilling the moves. When we spar, however, I'm unable to do anything more than get my hook on one leg and my other foot on the other hip. After that my opponents somehow manage to free the hook or just seem able to disregard my set up. I have no opportunity to think about an offensive move because I'm never really able to set up guard effectively. Anyone have any tips? I know to stretch opponents out by pulling the sleeves and pushing on the hip. I know to use my hook to control the close leg. None of this seems to help. I'm going to ask my coach tonight, but am interested to hear what others have to say too.
