TRIANGLE FROM MOUNT

The mounted triangle is one of the most punishing finishes in modern Brazilian Jiu Jitsu and one of the few submissions where the position itself — high mount — pre-arms several other attacks (armbar, arm triangle, cross-collar choke) before the triangle even sets up. The technique uses the same figure-four leg configuration as the guard triangle but executed from mount, with the bottom player's arm forced across the neck and the attacker's legs closing around the head from above.

The entry is established from high mount when one of the bottom player's arms has been forced upward — typically because the bottom player has tried to bench-press the attacker off or has reached for a hand-fight defense. The attacker S-mounts (rotates to the side and threads one leg behind the opponent's head), traps the upward-extended arm across the neck, and closes the figure-four. The finish is identical to the guard triangle: pivot past 90 degrees, lock the calf across the back of the neck, pull the trapped shoulder toward the opposite knee.

The mounted triangle's terror as a position is that it lives inside a chain of three submissions — armbar, mounted triangle, and arm triangle — that share the same setup. The attacker reads the bottom player's defense and chooses the corresponding finish, which means the bottom player must defend all three threats simultaneously to escape. Roger Gracie used this chain extensively at black belt, and Mica Galvao's modern game features the mounted triangle as a primary IBJJF finish. The technique is particularly devastating in MMA because the mount + triangle combination prevents the bottom player from striking up while the choke closes.
