Also known as Technical Mount — Bottom — the canonical term used on this site.
Training background: functional description
Descriptive — technical mount exposing the back
Back-exposed mount bottom is a descriptive name for the technical mount bottom position — naming the danger it creates, the back exposed to the top player.
Etymology. “Back-exposed” describes the consequence of turning under mount, the back opening to attack; “mount bottom” frames the position. The label foregrounds the risk the position carries.
Mechanics. Turning away under the technical mount isolates the near arm and exposes the back, so the defence keeps that arm connected to the body and resists fully turning: an arm pulled away from the torso both feeds the back take and abandons the frames, while an arm kept tight to the body preserves the chance to turn back in.
Cross-reference. “Step-out mount bottom” and “Half-turned mount” are sibling aliases. Full mechanical coverage on Technical Mount — Bottom.
