1. When your opponent has successfully set you up for a triangle choke in an attempt to submit you, stay calm and focus. Normally at this phase, your opponent is still at work establishing a perfect position to lock eveything up still giving you room to establish your own strategic escape-if you know what to do. For as long as you can keep his body bent, the key to your escape is still with you. But once your opponent manages to stretch his body, he gets full control of the position and can make the submission tighter and tighter until you surrender.
2. Keep his body bent, stay on your knees and never, at any circumstances, attempt to pull yourself from the position otherwise you make it easier for him to stretch his body and execute the choke easily. You might as well need to cling on his hands to protect yourself from his punches or elbows too.
3. On your knees, push yourself in using your upper body specifically your shoulders. If you have to, get on your feet and dig yourself in. By doing this, you bend his body more making it difficult for him to tighten his leg lock. More so, you get to loosen up his legs and reduce the pressure on your head giving you room to breath and stay focused. Simultaneously, the pressure you apply to break the lock and loosen his legs is deflected to his body squeezing his mid section making it difficult for him to breath air easily.
4. The more you force yourself in the more your opponent struggles to keep his legs in position which basically makes it painful for his legs and ankle. At this point, you get enough room to put your other arm in between, wedge it against his thigh and apply more pressure to break his position. This gives him no other alternative but to free up and let go. And now you're free with the advantage of being on top of your opponent.
