Inside Sankaku (also called the Saddle, Honey Hole, or Game Over position) is the most dominant leg entanglement position in modern grappling — a configuration where the attacker's legs form a triangle around the opponent's thigh from the inside, with the outside knee controlling the hip line, creating the optimal angle for the inside heel hook, the most devastating submission in grappling. [1] Inside sankaku is to the leg lock game what mount is to the positional game: the apex of the hierarchy, the position from which the highest-percentage finishes occur, and the position every leg lock player aspires to achieve. [1],[2] The position was systematised by John Danaher and demonstrated by his students (Eddie Cummings, Gordon Ryan, Garry Tonon) who proved that inside sankaku with proper heel control produces finishes at the highest levels of no-gi competition. [2],[3] Once inside sankaku is established with the heel secured, escape is extremely difficult because the triangled legs prevent the opponent from extracting their leg, and the inside heel hook attacks the knee ligaments (ACL, MCL) with minimal pain warning before catastrophic failure.

История и происхождение
Inside sankaku as a named, systematised position was developed by John Danaher in the 2010s, though the underlying leg entanglement has existed in catch wrestling and sambo. [1] Eddie Cummings was the first Danaher student to demonstrate inside sankaku mastery in competition (EBI, 2014-2016), followed by Garry Tonon and Gordon Ryan. [1],[2] The position has multiple names — 'saddle' (Craig Jones), 'honey hole' (Eddie Cummings), 'Game Over' (Gordon Ryan) — reflecting its importance to multiple competitive grapplers. [2],[3]

Эффективность
Inside sankaku is the highest-percentage leg lock finishing position in modern grappling — the inside heel hook from this position is the most commonly finished submission at ADCC and EBI. [1] Gordon Ryan's ADCC dominance (2019, 2022 absolute champion) was built significantly on inside sankaku heel hooks. [2],[3]

Биомеханический механизм
Primary Action — Triangling the legs around the opponent's thigh from the inside, controlling the hip line with the outside knee, and securing the heel for an inside heel hook
Joints Involved — Attacker's legs (triangled around the opponent's thigh — one leg hooks behind the knee, the other locks on top forming a triangle), attacker's hips (positioned to control the opponent's hip line — the imaginary line across their hips that must be controlled), opponent's knee (the target — the inside heel hook rotates the tibia relative to the femur, stressing the ACL and MCL)
Force Vector — The triangle creates inward compression around the thigh (preventing extraction), while the heel control enables outward rotation of the foot (attacking the knee ligaments)
Control Mechanic — Inside sankaku is the strongest leg entanglement because the triangled legs create a locked configuration that the opponent cannot easily disentangle from, AND the inside angle provides the optimal rotational direction for the inside heel hook (the most dangerous leg lock)
Позиция и вход
From single-leg X guard — From single-leg X (ashi garami), swim the outside leg over the opponent's thigh and triangle it with the inside leg — transitioning from the weaker outside ashi to the dominant inside sankaku [1]
From Imanari Roll — The Imanari Roll landing position is ideally inside sankaku — the legs thread around the target leg during the rolling entry
From De La Riva guard — From DLR guard, invert underneath the opponent and thread into inside sankaku — a common competition entry [2]
From 50/50 — From the symmetrical 50/50, fight to transition to inside sankaku by clearing the opponent's entangling leg and triangling around their thigh

✓Inside sankaku is the MOUNT of the leg lock game — achieving it should be the primary objective of every leg lock sequence (Danaher, Leg Lock Anthology) [1]
✓The outside knee MUST control the hip line — without hip line control, the opponent can extract the leg
✓The heel must be secured BEFORE applying rotation — reaching for the heel while in a loose entanglement results in the opponent escaping
✓Heel hooks from inside sankaku must be applied SLOWLY in training — the inside heel hook can destroy the knee before pain is felt; there is NO safe way to apply fast inside heel hooks
✓Learn the positional hierarchy: inside sankaku > cross ashi > outside ashi > 50/50 — always try to advance to inside sankaku [2]
✓The transition from outside ashi to inside sankaku is one of the most important leg lock skills — develop this transition specifically
✓Study Eddie Cummings' EBI footage — his inside sankaku entries and finishes set the standard for the position
Типичные ошибки
!Reaching for the heel without establishing the triangle — the legs must be triangled FIRST, then secure the heel
!Not controlling the hip line — loose knees allow the opponent to extract the leg
!Applying fast heel hooks — the most dangerous mistake in grappling; always apply slowly
!Crossing the legs incorrectly — the inside leg (closer to the opponent's hip) should be on top in the triangle
!Not addressing the opponent's boot defence — when the opponent 'boots' (points their toes to slip the heel), re-grip or transition to a different attack
!Staying in outside ashi when inside sankaku is available — always advance to the more dominant position

3Triangle the Legs — lock the triangle around the opponent's thigh with outside knee on top
4Control the Hip Line — squeeze knees to prevent extraction
5Secure the Heel — trap the heel in the elbow crease
6Apply Inside Heel Hook — slowly rotate the heel outward to attack the knee ligaments
7Finish — maintain controlled rotation until the opponent taps
