<human>:  How do I properly perform a triangle choke in jiu-jitsu?
<bot>: To perform a triangle choke in jiu-jitsu, start in an open guard with one of your legs wrapped around your opponent's shoulder and neck. With your other leg, push your opponent's arm away from their body and slide it through your legs. Secure a grip on the outside of their wrist and raise your hips up, forming a triangle with your legs. Make sure to keep your head pressed against your opponent’s shoulder and keep your elbows close. Pull tightly with your legs and move your hips forward to complete the choke.
