INVERTED TRIANGLE FROM MOUNT

The inverted triangle from mount is the variation of the mounted triangle in which the figure-four configuration is reversed, producing a strangulation from the opposite angle than the conventional mounted triangle. The technique is one of the rarer high-level submissions because the inverted angle requires specific opponent positioning that does not occur in every match, but when the setup presents itself the finish is fast and structurally difficult to defend.

The mechanics begin from established high mount, similar to the conventional mounted triangle setup. Instead of rotating to S-mount and threading one leg behind the opponent's head from above, the attacker rotates to the opposite side and threads the leg under the opponent's head and arm in the inverted direction. The figure-four locks with the inverted geometry, and the finish comes from the same hip-extension motion as the conventional triangle but produces the carotid compression from the opposite side.

Mikey Musumeci has used the inverted triangle in IBJJF competition as one of his unconventional finishing options that exploits opponents' lack of preparation for the rare configuration. The technique is also occasionally seen in MMA, where it appears naturally from kesa-gatame-influenced top control. Defensively the technique is countered by recognizing the rotation direction early and bridging to disrupt the angle, by maintaining elbow-tight defensive structure to prevent the leg-threading, or by hitchhike-style rotation of the trapped arm if the lock has closed.
