Opposite Triangle Escape
Opposite triangle escape — the reversed lock barely strangles, so the threat is the shoulder. Read the lock, take the arm home, use the reconfiguration.

The opposite triangle — hantai sankaku — is the reversed-lock triangle. For the attack, see Opposite Triangle. The trapped head-and-arm configuration is identical to a front triangle; what differs is the figure-four itself, locked on the reversed side with the choking knee on the same side as your trapped arm rather than across from it.
⚠ The good news and the bad news are the same fact: as a strangle it barely works. With the lock reversed, the choking leg’s calf never crosses the carotid line, so the bilateral compression a front triangle depends on is unavailable — and squeezing harder does not fix a geometric problem. ⚠ What it does platform is an armlock. The kimura is the finish this configuration actually threatens, and a defender who reads the reversed lock as a weak choke and settles in to wait is defending the wrong submission.
It is rarely chosen deliberately. It arises mid-scramble or mid-entanglement, when the legs close on whichever configuration the exchange offers and the figure-four lands on the available side rather than the correct one. Unlike most triangle pages the standard escapes do apply — you have posture and you can stack — and you have more time than the shape suggests, provided you spend it on the arm.
Elevated RiskOpposite Triangle (Defence) is an elevated risk technique. ⚠ The hazard here is not the strangle. With the figure-four locked on the reversed side the calf never crosses the carotid line, so the vascular compression a front triangle produces is largely unavailable. What the configuration does platform is a shoulder lock — the trapped arm is held in a position from which a kimura is readily available, loading the shoulder in internal rotation with the legs supplying the anchor. A defender waiting out a weak choke is waiting inside a live armlock. Serious injury can occur The strangle may never arrive. The shoulder lock arrives at the speed of any kimura — the travel between fine and damaged is short and gives little warning..
