Baratoplata
The Baratoplata in no-gi: a shoulder lock that clamps the opponent's elbow between the thighs and turns the wrist outward, attacked mainly from closed and half guard.

The Baratoplata is a shoulder lock that isolates the glenohumeral joint by immobilising the elbow. The attacker traps the opponent’s elbow between their own thighs, which fixes the middle of the arm in space; with the elbow held, the shoulder has nowhere to rotate to, and the lock is finished by turning the wrist outward. The load lands on the shoulder capsule and the rotator cuff tendons rather than on the elbow, even though the elbow is the part being clamped.
The distinguishing feature is where the control lives. Most shoulder locks in the corpus hold the arm at both ends — the kimura’s figure-four takes the wrist and the elbow, the omoplata’s leg wrap takes the shoulder line. The Baratoplata takes the middle and lets the ends move: the thighs own the elbow, one arm threads behind that elbow with the palm on the attacker’s own thigh to close the frame, and the free hand steers the wrist. Because the clamp is made of legs, it survives a strong defensive arm in a way a hand grip does not.
The name carries its originator’s nickname. It began as a bicep slicer — the same elbow clamp, closing the arm rather than turning it — and was converted into a shoulder lock so it could be used under rulesets that restrict compression locks at lower grades. That history explains why a shoulder attack lives in the armbar hub next to the bicep slicer: they are the same trap with two different finishes.
The Baratoplata should not be confused with the Tarikoplata, which attacks the same shoulder from a similar but distinct angle and uses a different entry and finish mechanism.
Elevated RiskBaratoplata is an elevated risk technique. Shoulder lock. Stress accumulates in the shoulder joint's internal rotation and adduction range before significant pain is produced. The shoulder can be damaged before the defender recognises the severity of the position they are in. The Baratoplata is particularly concerning because it is often encountered mid-omoplata defence — when the defender is already under pressure and may not recognise the Baratoplata as a separate submission with its own danger profile. Serious injury can occur before significant pain — the shoulder's internal rotation limit is approached without reliable warning.
