So, I am trying to go back to basics. I have been playing with the rubber guard a lot and I like it, but when I can't break down someone's posture, I go back to standard guard positions. I have neglected my butterfly guard for a long time, and I miss the options available from it. So, I started working on it again this past week, and damn it, I can't keep ANYONE in it. I instantly get passed to side mount. Even if I have a single butterfly hook in and a tight open guard, my knee gets popped down and I get passed. I love my guard, so I don't want to immediately go back to neglecting butterfly just because I'm stuck. So, how do you keep someone in your butterfly guard (particularly someone larger/stronger as I am a little guy). What is your favorite sweep from butterfly? Thanks.
