The triangle choke uses your legs, the strongest muscles in your body, to choke both carotid arteries at once. Here is how to actually lock it in.

The triangle choke uses your legs to squeeze both of your opponent's carotid arteries at once. Your legs are the strongest muscles in your body. That's exactly why this choke works so well. It traces back to early 1900s Kosen judo, long before BJJ adopted and refined it.

That 90-degree angle adjustment is the difference between a loose triangle and a fight-ending one. Without it, your opponent can posture up and stack you. With it, their trapped shoulder crosses your body's centerline. Escape becomes far harder from there.
Posture up right away. Keep your trapped arm tucked, not extended across your body. Stacking your opponent by driving your weight forward can also break the choke's leverage before it fully locks.
The triangle works the same in both. No-gi grapplers often set it up faster, since there's less fabric to control. But the leg mechanics and the 90-degree angle stay exactly the same.
Once you have the triangle down, our omoplata guide and armbar guide share several of the same closed guard entries.
Most likely you skipped the 90-degree angle adjustment. Without it, your opponent stays too square to you and can posture out. Angling your hips is what actually locks the choke in place.
Yes, and often faster than in the gi, since there is less fabric for your opponent to use to defend. The leg mechanics stay identical.
Yes. It is a blood choke rather than a joint lock, so it is legal at every belt level under IBJJF rules.
Posture up right away and keep your trapped arm tucked rather than extended across your body. Stacking your opponent by driving your weight forward can also break the choke's leverage before it locks.
