Mounted shin choke

Mounted shin choke is the descriptive name for the domplata — the mount submission that traps one arm under the thigh, blocks the neck with the foot, and finishes by sitting back.

Etymology. The descriptive form places the technique in the shin-pressure family and says which end of it you are on. The -plata suffix does the opposite: it suggests kinship with the omoplata and the gogoplata that is a matter of naming convention rather than mechanics, and it has repeatedly attracted lineage claims the technique does not support.

Mechanics. From mount the attacker goes under the near arm and pulls it clear of the ribs, slides the knee up toward the head as though beginning an armbar, and uses the shin to pin the free arm to the mat. With a grip at the shoulder and the hips driving, the opponent is turned onto their side; the leg then swings over the head so the trapped shoulder sits beneath the thigh, and the attacker sits back. The finish is a pull on the arm against a push on the head — a shoulder lock and a neck block loading together as the body travels away, rather than a weight-driven compression from above.

Both structures warn late. The airway gives immediate distress without a graduated ramp, and a rotationally loaded shoulder reads later than an elbow extension. Because the force comes from distance rather than effort, a fast sit-back can cross both thresholds before it feels like anything is being applied.

Cross-reference. The same neck reached from underneath is the gogoplata; the other mounted shin choke, finished by pressing down rather than sitting back, is the locoplata. Full mechanical coverage on Domplata.
