Arm Triangle from Mount

Arm Triangle from Mount is a finishing attack built around a handful of repeatable controls. Mount with an underhook on one side, the shoulder driving into the chin to walk the hand up. Another common starting shape: top player has begun the caveman necktie and the opponent sits out, exposing the near arm and ribcage as he turns to escape. The ideas that hold it together are removing the bridge is the prerequisite to the slide, head-and-arm capture replaces the gi grip in no-gi, and follow the rotation of a sit-out into a knee-slide mount.

The arm triangle chain is a sequence of small controls, not one athletic burst. Swim the underhook in and walk the shoulder up to the head. Bring the elbow around the head and palm-to-palm grip. Pull the head off the floor while sliding the knee to the elbow to take the bridge away. Soft-land into the leg-side armbar with the head and arm still trapped. As the opponent sits out, drive the shin across the belly catching the near armpit instead of the neck. Post the free hand on the mat and circle the knee across the stomach into mount. Settle deep so the strangle arm pinches the neck and trapped shoulder together. If needed, lock a figure-four with the second arm and crunch the shoulder for the finish. Leg-side cross-body armbar landed softly with the head and arm trapped and the arm extended.

Later in the arm triangle, trap the near arm to convert a failed necktie into a head-and-arm strangle, attack early to prevent mental reset, and the bottom player's own shoulder is the choking surface tend to decide whether the position stays on track. Watch for these mistakes: Going under the head, which can be trapped or bridged off. Trying to land hard, which gives the opponent a window to escape. Shooting for the neck instead of the armpit and getting bumped off. Rushing the squeeze without first settling weight in mount. The high-percentage version of arm triangle from mount is the one you can still chain when the first squeeze is defended.
