{"slug":"k-guard","name":"K Guard","aliases":["K-guard","matrix guard","false reap entry"],"category":"guard","format":"both","level":"advanced","summary":"A close-range open guard that wedges beneath the opponent's hip to access the far leg, off-balance, or enter leg entanglements.","overview":["K guard uses a high inside leg frame and close hip connection to reach beneath the opponent's far-side base. It can appear from supine open guard, closed guard, or as a reaction to an opponent stepping close.","The position is especially influential in modern no-gi leg-lock systems, but it also supports gi sweeps and back exposures. The guard player must manage distance carefully: too far away loses the hip wedge, while collapsing under uncontrolled weight can compromise alignment."],"keyPrinciples":["Build a strong wedge at the near hip before reaching for the far leg.","Keep your own knee line aligned and mobile.","Control the far leg at the knee or ankle rather than reaching without connection.","Off-balance first; enter the leg entanglement as the opponent reacts."],"entries":[{"label":"Supine open guard","description":"Frame the near hip and thread the inside leg high as the opponent closes distance."},{"label":"Closed guard","description":"Open at an angle while maintaining upper-body control and insert the hip wedge."},{"label":"Half guard transition","description":"Create enough inside space to bring the top leg beneath the far hip."}],"continuations":[{"label":"Backside 50/50","description":"Rotate under the far leg while following the opponent's hip."},{"label":"Single-leg X","description":"Redirect the captured leg into a straight-ashi sweeping position."},{"label":"Kneebar line","description":"Control the far knee and extend into a ruleset-appropriate leg configuration."}],"defenses":[{"label":"Control the top knee","description":"Prevent the high inside frame from wedging beneath the hip."},{"label":"Square the hips","description":"Turn to face the guard player's legs before the far leg is isolated."},{"label":"Retreat with posture","description":"Increase distance while clearing grips rather than twisting the trapped knee."}],"relatedTechniqueSlugs":["fifty-fifty","single-leg-x","inside-heel-hook","kneebar"],"athleteSlugs":["lachlan-giles","mateusz-szczecinski","spencer-quayle","lucas-kanard"],"rulesetNote":"Leg-lock legality changes substantially by age, belt, division, and ruleset.
