It includes low, mid, high-crotch, sweep-single, and run-the-pipe families.","Jiu-jitsu adds submission and guard considerations. Attackers must protect the neck from front headlocks and should finish in a way that limits immediate guard entries. The single leg also appears constantly as a wrestle-up from seated and half guard."],"keyPrinciples":["Connect head, hands, and shoulder to the captured leg.","Keep posture strong enough to resist front-headlock pressure.","Move the opponent's upper body and standing foot in different directions.","Transition between finishes instead of holding a stalled leg."],"entries":[{"label":"Hand fight","description":"Create an angle outside the opponent's lead arm."},{"label":"Wrestle-up","description":"Rise from guard while keeping the near leg connected."},{"label":"Arm drag","description":"Expose the near hip and drop to the leg as the opponent squares."}],"continuations":[{"label":"Run the pipe","description":"Turn the captured knee while removing the opponent's standing base."},{"label":"Double leg","description":"Collect the far leg when the opponent squares and lowers their hips."},{"label":"Back control","description":"Climb behind the hips when the opponent turns away."}],"defenses":[{"label":"Head position","description":"Put your head above and inside the attacker's head."},{"label":"Whizzer","description":"Use an overhook and hip pressure to prevent the attacker from climbing."},{"label":"Free the knee","description":"Turn the captured knee toward open space while hand fighting."}],"relatedTechniqueSlugs":["wrestle-up","double-leg-takedown","guillotine-choke","back-control"],"athleteSlugs":["owen-livesey","jozef-chen","nicky-ryan","andrew-tackett"],"rulesetNote":"Scoring and permitted grips vary by promotion and division.
