— also widely known as 80/20 — is the asymmetric leg entanglement where one player has dominant inside space and hip control while the other player has a residual entanglement. The percentages name the positional share: the 70% player controls the dominant share of the position; the 30% player retains a partial entanglement but has no realistic submission threat and severely limited escape resources.
From 70/30, the advantaged player has access to the inside heel hook, kneebar, and Z-lock; the outside heel hook belongs to the outside-ashi family and is reached by re-aligning through 50/50 to outside ashi. The breadth of submission options makes this the highest-threat position in the leg entanglement family short of cross ashi — and unlike cross ashi, the multi-submission picture is more difficult to defend against because the defender cannot over-commit to blocking a single attack. Understanding 70/30 is an Advanced-level study because it requires a foundation in 50/50, backside 50/50, and outside ashi before its mechanics become legible.
Elevated Risk70/30 (80/20) is an elevated risk technique. The 70% player has structural access to the inside heel hook, kneebar, and Z-lock. The 30% player is in a significantly worse position than in 50/50 — their defensive resources are limited and multiple submissions are available simultaneously. Serious injury can occur with very little movement once any submission grip is established.
