When opponents became familiar with Colin Oates’s leg escape they would start bringing their arm in tight to their body, to prevent him from going under their armpit. So he developed a reverse variation, prising their elbow up and entering from the opposite direction.

Once inside, he secures the arm and climbs up over their body and onto the opposite side, kicking free his leg and securing the hold-down.

From the guard position Oates takes his partner’s belt and rolls him onto his side. The partner tightens up, not allowing Oates to go under the armpit with his right arm. So instead Oates prises up the elbow, pulling it in towards his chest. He then releases the belt with his left hand, entering the crook of the elbow from the opposite direction.

Then comes a feed of his lapel, which is what secures the top half of his partner’s body.

Now he is free to roll over the partner’s body. Once on the other side he is able to kick his leg out and secure the hold-down.
So the three stages are: prising up the elbow to get the arm inside. Feeding of the lapel. And rolling to the other side of Uke’s body, as he kicks the leg free.
