Attack him and try to breach his guard

You step forward, trying to take you brother's head between your arms and hip toss him on the ground. Unfortunately for you though your opponent is bare chested and you are used to make throws using the Gi as leverage, so your move is not so effective. Your brother can easily slips his head away from your grip and take you from behind. You have just a moment to brace yourself, as he masterly connects his hands around your waist and body slams you backward. You fall hardly on the grass, your back aching in pain. Many whistles come from the crowd that has gathered around you. Your brother jumps on you immediately, landing on your abs, and in no time hooks his feet on your tights, putting you in a painful gravepin. Josh tries also to push your arms on the ground but, being stronger, you can hold his weight. He is painfully spreading your legs and you wonder how longer you can resist.
