K-Guard System Guide

The K-guard in BJJ: position mechanics, entries from open guard, leg lock attacks, and how the Danaher Death Squad uses it.
The K-guard is a powerful outside-leg entanglement position that serves as a launching pad for outside heel hooks and back takes — a cornerstone of modern no-gi leg lock systems.
What Is the K-Guard?
The K-guard (outside ashi garami or outside sankaku) is a leg entanglement where you control the opponent's outside leg: your inside knee points upward, your outside leg hooks behind their near hip, and you control the ankle of their far leg. The "K" shape comes from the leg configuration.
K-Guard vs. Ashi Garami
Standard ashi garami controls the inside leg with the leg between the opponent's legs. K-guard controls the outside leg, which threatens the outside heel hook — one of the most powerful and difficult-to-defend submissions in grappling. K-guard is preferred when inside position is blocked.
Entries to K-Guard
Common entries: from single-leg X-guard when the opponent steps over your inside leg, from failed inside ashi entries when they defend by turning out, during standing guard pulls where you reach for the outside leg, or from butterfly guard scrambles.
Attacks from K-Guard
The primary attack from K-guard is the outside heel hook — rotate your torso to outside while controlling the ankle and driving the knee down. Secondary attacks: inside heel hook if they turn in, kneebar if they straighten the leg, back take if they stand and turn.
K-Guard in Competition
The Danaher Death Squad (Gordon Ryan, Garry Tonon, Nick Rodriguez) has made K-guard a staple of modern no-gi. At ADCC 2022, Gordon Ryan used K-guard entries to set up outside heel hooks in multiple matches. It requires significant lower body entanglement training to use safely.
Frequently Asked Questions
K-guard itself is safe to practice. The outside heel hook (its primary finish) requires careful training — only practice with experienced partners who understand heel hook safety and always tap early.
Entering K-guard can be practiced at purple belt and above. The outside heel hook should only be trained where it is permitted — typically nogi training at advanced levels.
The K-guard position itself is legal. Outside heel hooks are not legal in most IBJJF gi divisions and are restricted by belt level in no-gi. Check the current IBJJF no-gi ruleset for your division.
