Under-chin choke
Also known as Short Choke — the canonical term used on this site.
Training background: Descriptive term
Descriptive — choking arm seated under the chin
Under-chin choke is the descriptive name for the short choke — the back-position strangulation in which the choking arm is seated under the opponent’s chin with the elbow below the jaw line, closing the compression from a shorter arm-around-neck angle than the rear naked choke’s full wrap.
Etymology. “Under-chin” specifies the arm position relative to the opponent’s anatomy — the choking arm is below the chin rather than wrapping around above it. The descriptor appears in coaching vocabulary that distinguishes the short-choke geometry from the rear-naked-choke’s longer wrap. “Choke” attaches the submission category.
Mechanics. The short-choke geometry requires bilateral compression with a tighter wrap than the rear naked — the under-chin position means the choking arm covers less of the neck circumference, so the closing pressure must be more precise to load both carotids.
Cross-reference. “Short choke” is the canonical site label; “control arm choke” is an alternate descriptive name. Full mechanical coverage on Short Choke.
