Keep him from being able to get his hips under yours, and keep your head up. If he shoots you sprawl. Work pummeling drills and learn to tie him up so he can't set up his takedown.
Your hips should be lower then his, but make sure your head stays up, and if you can get his down. If you look down you will get snapped down and land in a front headlock get a few knees and end up on your back
