Master Rickson Gracie demonstrating
his open guard on me
The open guard is a core position in Brazilian jiu-jitsu. Competitors and fighters within and outside the Gracie family have used it for generations to stay safe on the bottom, escape back to their feet or even reverse or submit their opponent but what good is a guard as a defensive / offensive tool if it's constantly getting passed?
Do you want to make your open guard impassable? Start every sparring round from the bottom of the side control. Don't even worry about escaping to begin with. Just focus on preventing the mount / knee on belly / North / South and defending their submission attacks.
Why will this improve your guard retention?
