So my biggest problem rolling was getting smashed in half guard. Every time I rolled I would end up getting cross faced for 2/3 the round. I spent every session for close to 6 weeks working half guard techniques including the lockdown and conventional sweeps. Now , as soon as I get half guard most people, blue belts included, bale instantly and let me get butterfly or stand up. I guess that if I want to use these techniques I need to develop some kind of open guard game or get snappier with closing the full guard if I'm going to scare them into trying to pass my half guard. I guess.
