Brazilian no-gi competitor and ADCC absolute champion. Heavyweight pressure-passing game centred on body-lock and double-under passes, takedown-led entries from clinch positions, and pin-to-mount finishing pipelines.

is a Brazilian no-gi competitor whose ADCC results across multiple cycles — including absolute-division success — established him as one of the central heavyweight pressure-passing competitors of the current generation. The structural feature of his game that travels across rule sets is the heavyweight body-lock template: standing-clinch entries that resolve into top-position passing, body-lock and double-under passes as the central passing pair, and pin-to-mount progressions where finishing pressure concentrates. He competes out of Atos Jiu-Jitsu and is one of the named figures in the InGrappling state-of-no-gi-2026 analysis as a representative of the heavyweight elite.

Body-lock pass and double-under pass as the recurring passing register across his match record. The reproducibility of the passing rate against ADCC-level opposition is the empirical claim about his record.

Standing clinch as the primary engagement context. Duarte’s standing game is clinch-led — body-lock entries from over-under and head-and-arm exchanges, with single-leg and double-leg attempts as supporting techniques rather than as the primary takedown register. the underhook controls the hip governs the clinch geometry; the underhook is the load-bearing connection that determines which direction the takedown completes. See over-under clinch and front body lock.

"The side of the body with the underhook controls the hip on that side."

See full invariant page → Body-lock pass as the central passing register. Duarte’s passing repertoire concentrates on the body-lock pass — the connection-led passing technique that loads up passing is pinning as its structural front end. The body-lock connection at the bottom player’s hip-and-back becomes, without re-establishment, the chest-to-chest connection of a side-control or mount pin. The pass is not a separate phase from the pin; it is the same connection completed across the legs. See body-lock pass.

See full invariant page → Double-under pass as the secondary register. Where the bottom player’s foot line denies the body-lock entry, the double-under pass is the secondary register. clear the feet applies as the structural front end; the pass advances by stacking the bottom player and removing the foot line as a defensive option. See double-under pass.
