Here is a advanced technique that you can use to catch your opponent off guard and turn the tables to end up on top.
In this situation, I have gone for an armbar and my opponent has postured up and is getting ready to pull his arm out.
Here is the video of the technique, the step by step is below.
Eddie is in my guard
I cut my angle for the armbar
I throw my leg over for the armbar
Eddie starts to stand up...
I underhook the leg to prevent from getting slammed- however, Eddie's elbow has freed up, so Im not feeling the arm bar anymore
Knowing that I have lost the armbar, I dig my heels into Eddie's back and get way up on my shoulders
Pushing off my heels, I lock my right arm tight to Eddie's left leg and roll backwards over my right shoulder.
I land keeping a tight grip on Eddie's left leg, as I land I am driving my shoulders back as I pull forward on Eddie's foot with my grip
I keep driving back, until Eddie falls back
I reach across, and cover Eddie's knee and hip
I place my right knee on Eddie's belly for the reverse knee ride position
