my two favs ill try to explain. my first one is pretty standard breaks just about all guards.
after you "sweep your hair" then posture up, i control the hips by pressing my right elbow and forearm inside their left thigh while either grabbing their belt or just controlling their hips with my palm, fingers bent mr miyagi style. after you are postured and hips are controlled, their attacks are pretty much stuffed. if you feel them open guard, you should be able to force their left thigh to the matt and pass to side control. if not, then put your right knee in their butt cracks and with your left leg, stretch it straight back. that will break most guards and you can like i said earlier force their thigh to the matt to transition to side.
another fav of mine is def a hollywood move. i do it more for fun or when i have someone with an impossible guard. i trap one arm while posturing up. then i start to rock back and forth. when im ready, with a burst of power, i will step over the shoulder of the trapped arm. so their right arm trapped, rock, and with my right leg, burst over their right shoulders.
you can sometimes get an achilles crush out of the ensuing scramble, a knee bar or a heel hook. ill do that same technique to get out of triangles too.
