Here is a new mount escape that work for both gi and no gi Jiu Jitsu by Clockwork BJJ head instructor Josh Griffiths

This is a lower body pass, involving controlling your opponents legs, tripod-ing, freeing your trapped leg, and ending in side control.

Start From Half-Guard Top, your right leg is trapped in Half-Guard :

1 – Dive your head down, end posting on it with your left ear on your opponents left hip, and putting heavy pressure on your opponents solar plexus. (be heavy to prevent choke attempts)

2 – lock your wrists around your opponents legs. Try to be between their hips and knees, but closer to their knees.

3 – squeeze your arms together to weaken their leg clamp on your trapped leg.

4 – kick your trapped leg back and move to side control.

5 – Back-turn, scoot your back up their body and prepare to mount

Option starting from closed guard:

A – grab opponents armpits. lunge knees forward, like you’re doing squats. Repeat this until their guard opens.

B – Push their right knee down with your left hand, while you pin their left hip with heavy pressure from your right hand.

C – pass into half guard, go to 1 above and start.

(If you time it right you can just sit right up and completely reverse your opponent. This is not a high-percentage move and usually works best with a lighter opponent. You hit this reversal by keeping your fett very close to your butt and as your opponent backturns, your kick and swing your hips out. Think pommel horse in gymnastics, or breakdancing, depending where you hail from. )

If you are like the rest of us, then this second alternative will likely work better.

1) Start with your opponent in side control on your right. Free your inside arm. Keep your elbow down and your hand on your opponents hips to keep them from rotating into north/south.

2) After they back turn move your free hand into their armpit outstretch and lock your arm. This keeps them low on your body and off your chest and allows you to work on freeing your other arm. Rock from hip to hip to free your outside arm. (Try turning towards the outside, but be careful not to give up the back.)

3) Now that both arms are free it’s time for them to get off of you. Put both your left hand in their armpit and your right hand on their hips, but don’t extend your arms fully. Now prepare to bridge by scooting your feet towards close to your butt.

4) explosively bridge up. Go for height. Next, before your drop forcefully extend your arms shoving your opponent away from you as your body drops. As you drop, scoot your hips as far back as possible.

5) Now that you are sitting up, grab your opponents belt with your left hand (this is like the conter to a single-leg.) Keep pressure down on their neck with your elbow.

6)Take the back by continuing to scoot your hips out and trying to kick out the near knee and grabbing the far armpit with your right hand, rolling your opponent towards you backwards.

7) End in back control.
