Leg-side pin bottom

Leg-side pin bottom is the descriptive no-gi name for the bottom-player position in reverse kesa gatame — the pinning configuration in which the attacker faces the bottom player’s legs from the side rather than facing the head as in standard kesa gatame.

Etymology. The “leg-side” descriptor flags the orientation: the attacker’s torso faces toward the bottom player’s legs, with the attacker’s hips committed to that direction. “Pin bottom” attaches the bottom-player perspective. The label predominates in no-gi vocabulary that prefers descriptive English over the Japanese ushiro kesa gatame or the literal “reverse scarf hold.” The bottom-side framing emphasises the defensive perspective and the position’s distinct escape mechanics relative to standard kesa gatame bottom.

Mechanics. The bottom player’s defensive priority is destabilising the attacker’s hip-and-chest connection before initiating any escape — the leg-side orientation means standard kesa gatame escapes (bridge toward the head, frame against the near arm) don’t apply directly; the bottom player must work the legs and hip line where the attacker’s weight commits.

Cross-reference. “Reverse scarf hold bottom” and ushiro kesa gatame bottom are alternate names. Full mechanical coverage on Reverse Kesa Gatame Bottom.
