Asymmetric 50/50
Also known as 70/30 — the canonical term used on this site.
Training background: descriptive
Descriptive — asymmetric leg-entanglement variant
Asymmetric 50/50 is the descriptive name for the 70/30 leg entanglement — flagging the family’s relationship to 50/50 with the “asymmetric” qualifier that captures the imbalanced leverage state.
Etymology. “Asymmetric” specifies the tactical state (imbalanced rather than symmetric); “50/50” attaches the broader family reference. The compound predominates in instructional contexts that frame the position relative to the symmetric 50/50.
Mechanics. The asymmetric leverage produces attacking advantages for the higher-leverage player — the bottom player works to convert the imbalance back toward symmetry or escape entirely.
Cross-reference. “70/30,” “80/20,” “Seventy-Thirty,” and “Eighty-Twenty” are alternate names. Full mechanical coverage on 70/30.
