Triangle from Berimbolo

Triangle from Berimbolo is a transition between related positions built around a handful of repeatable controls. Attacker has rotated under the opponent's hips during the berimbolo with the De La Riva and far leg control intact. Another common starting shape: bottom player has set the De La Riva hook, broken the opponent's base, and spun underneath in the berimbolo position. The ideas that hold it together are triangle lock as a back hook, leg trap before grip work, and leg triangle traps the limb during the transition.

The triangle chain is a sequence of small controls, not one athletic burst. Cross the De La Riva leg deep behind the opponent's far thigh. Triangle the second leg over the locking ankle. Pull the opponent down into the lap with the lapel grip. Establish seat belt grip from the new back configuration. Stretch the arm and pass the foot under the opponent's leg to set the triangle on the leg. Keep the opponent's knee inside, then close the triangle by hooking the other leg over. Release the collar grip and shoulder-roll facing the opponent's feet. Grip the drawstring, take the second collar, hip-escape, and place the second hook for the back. Attacker has triangle-locked the legs around one of the opponent's thighs and arrived in a controlled back position.

Later in the triangle, shoulder-roll direction sets up the back climb tend to decide whether the position stays on track. Watch for these mistakes: Triangling the wrong direction so the leg slips. Not pulling the opponent into the lap to load the back position. Letting the knee come outside, breaking the triangle line. Shoulder-rolling away from the feet, losing the angle for the back take. The high-percentage version of triangle from berimbolo is the one you can still chain when the next position is contested.
