I generally can break people down and keep breaking them down if they posture. I also do pretty well attacking arm bars and triangles, just being annoying in guard lol. Some people who are just stronger or have strong posture say Bicep control ( hands on the arm pits) can give me a hard time isolating an arm or doing anything really. If someone is shutting down your guard game with strong posture but isn't trying to pass what is the next move?
