I too need another option for breaking the guard. The knee in butt turn hip isn't working for me, it leaves out to much space. What I am starting to do is just reach back to the ankle and put one arm in, they always go for the triagnle and open the guard. I am pretty good at passes after the guard is open.
One more thing that I need help on is butterfly guard. When I go for the classic double overhook sweep I am always getting passed. As soon as I go to my side to sweep he jumps to the other side.
Please help, if there are any video's that you have they would greatly help. I learn better seeing something
