The triangle choke is a very effective move used in the MMA world which ultimately strangles the opponent by encircling the opponent’s neck and one arm with the legs in a configuration similar to the shape of a triangle. This causes the blood flow to be restricted to the carotid arteries, therefore causing the opponent to quickly tap out. If he doesn’t tap out quickly the loss of blood to his brain will ultimately make him pass out.
The triangle choke is one of the most common submission holds that is applied in the full guard position. It is best when this submission is ussed early in the fight because as the fight progresses both you and your opponent become more sweaty and more slippery therefore it will be harder to apply the triangle choke.
To properly execute a triangle choke you need to get your opponent in the open guard using collar and sleeve control and you mush place a foot on his hip and shoulder, chances are your opponent will try to counter this by coming under your leg with his left arm, that is when you arch your hips and throw your leg over your ankle securing the triangle choke and to make it more effective pull your opponents arm across your stomach as this applies more pressure and makes them tap out even faster.
Here are a few videos to demonstrate how to use a Triangle Choke to make your opponent tap out.
