I have a decent top game with decent take downs so I don't play on my back that much. If I do I am trying to sweep them from butterfly and half guard. Lately I have been trying to develop a deadly closed guard game but I feel like its just a matter of time before I open it up and they try to pass and then I have to stand up or get on my knees and shoot for a take down. I have been struggling with closed guard for a while and I know all the basics to it; wrist control, sleeve control, neck control, posture, using my legs in unison with my abs. However I always seem to just get passed. Does anyone pull closed guard and succeed with sweeps and submissions? I feel as if everyone now a days plays butterfly, half and open guard for sweep and submissions. Just getting frustrated with my bottom game any tips/suggestions videos would be much appreciated.
