Submission: Inverted Triangle

Transitioning to an inverted triangle from a lapel choke:

1. Start with a lapel choke attempt from the back. If you sense the choke isn't secure or your opponent is escaping, prepare to switch to the triangle.
2. As your opponent begins to slip out, use your outside leg (left leg in this case) to hook over and trap their arm.
3. Push your opponent's body slightly down with your grips while pulling your legs up to create space for the triangle.
4. Shift your opponent's position so their back is nearly on the floor, giving you a better angle to lock in the triangle.
5. Lock the triangle with the leg that was on the inside, maintaining the lapel grip if possible, and continue to pull for the choke.
6. If the triangle is tight, a slight pull should elicit a tap. If the grip on the lapel is lost or uncomfortable, you can let go.
7. Without the lapel grip, lock your legs and use both hands to pull up on the inside of your opponent's elbow to secure the submission.

There are two variations to finish the submission: with the lapel grip maintained or by letting go of the lapel and focusing on the triangle lock.
