AMERICAN·NO-GI·SILVER FOX BJJ (KAREL PRAVEC)·10TH PLANET JIU-JITSU (TRAINING)

American no-gi competitor, ONE Championship grappler, and the inaugural ONE Atomweight Submission Grappling World Champion. Game centred on leg entanglement entries from seated guard, single-leg X mechanics, and the heel hook as the primary finish.

is an American no-gi competitor whose competitive output across EBI, Polaris, and ONE Championship grappling cycles established her as one of the more leg-attack-oriented competitors at her weight. The structural feature of her game that travels across rule sets is the seated-guard-into-leg-entanglement pipeline: butterfly and single-leg X exchanges resolved into ashi-garami family entries, with the inside heel hook as the dominant finish where the rule set permits. The promotional context — ONE Championship grappling at full submission rules — made her competitive output one of the more visible no-gi specialty acts at promotional scale in the 2022–2025 window.

ONE Atomweight Submission Grappling World Champion — inaugural title at the weight class. The promotional title is the load-bearing single competitive credential for the no-gi specialty at full-rules promotional scale.

EBI Combat Jiu-Jitsu and EBI submission-only event finishes across the 2018–2021 cycle.

Polaris and submission-only event appearances with finishes by inside heel hook recurring across multiple matches.

Seated guard as the primary engagement context. Kelly’s offensive game starts from a seated-guard exchange rather than from a standing exchange. The position loads up hip mobility as the structural front end and hand posts create offence as the engagement mechanic — the hand-post and hook engagement defines the entry geometry into the leg-entanglement tree. See seated guard.

"Destabilising the top player to their hands removes their ability to pass and creates submission opportunities."

See full invariant page → Single-leg X as the central transitional position. The single-leg X family operates as her principal route from a seated-guard engagement into a leg entanglement: the hooks are established under the standing leg, the destabilisation loads through destabilisation precedes control, and the position resolves either into a sweep or directly into an ashi-garami entry. inside space control governs the destination state regardless of the path used to enter. See single-leg X.

"Inside space control — maintaining the attacker's hip in the space between their hip and the opponent's hip — prevents the opponent from extracting their leg and determines which submissions are available."
