Monoplata Escape
Monoplata escape — one leg instead of two, so your free hand is worth more. Shrug and keep the arm tight, post the free hand to kill the hip rotation, roll with it.

The monoplata is the mount-side member of the omoplata family. For the attack, see Monoplata. From mount or S-mount your arm is trapped bent — the chicken-wing shape, elbow flexed, hand near your head — and pinned; the attacker swings a leg over your head and shoulder so the shin presses across the shoulder line, then sits back armbar-style. The shoulder is fixed under the leg and the sit-back drives it into internal rotation.
⚠ Your bent elbow is what invited it. The armbar available from the same mount-side position needs a straight arm and attacks the elbow; the monoplata takes the arm that stays bent and attacks the shoulder. The two finishes split your arm-shape answers between them, so straightening to deny the shoulder offers the elbow, and keeping the elbow flexed to deny the armbar offers the shoulder. The escape is not a choice of arm shape — it is getting the shoulder out from under the leg before the sit-back begins.
A bottom-guard version exists and is taught in some lineages, where the same shoulder attack is played from underneath. It is the minority form. ⚠ A defender who has only ever met it from the bottom will not recognise it arriving from mount — which is where it is most common, and where the attacker has gravity.
Elevated RiskMonoplata (Defence) is an elevated risk technique. A shoulder lock loading rotation, driven by hip movement rather than by a two-leg wrap. The looser configuration means the force arrives more gradually than a tarikoplata's, which is genuinely more time and also a reason defenders misjudge it — a rotation that builds slowly still reaches the capsule, and shoulder rotation gives poor warning at any speed. The gradual build invites riding it out, which is the wrong instinct on a joint whose signal lags the load. Serious injury can occur Seconds, arriving more gradually than the tighter plata variants — which invites waiting rather than acting..
