In this clip we see the competition variations of Colin Oates’s arm tie roll.

On his way to a bronze medal at the 2013 Rijeka Grand Prix Oates uses the standard variation of his arm tie roll against Spain’s Cases

Oates brings his right knee into play to help turn his opponent onto his back.

Once in the hold there is no way out.

Here you can see just how tight he is on the arm.

Against Hungary’s Zambori in the 2015 Paris Grand Slam Oates uses his Sumi gaeshi to bring his opponent down into Newaza.

He initially catches the arm and starts to adopt a Juji gatame entry position, before switching to the arm tie.

After working hard to get Zambori on his back he ties up the jacket and then works to get his legs free… But with the arm now fully tied up there is no escaping.

On route to a silver medal at the 2015 Baku Grand Slam, Oates uses Ashi waza to get Russia’s Ardanov into groundwork... From there he catches the arm and spins around to the top of Ardanov’s body. Then comes the turn and the immediate tie up of the jacket.

With the top half of the body now tight it doesn’t take long before he’s released his legs and is into Osaekomi.

At the 2013 Miami Grand Prix it’s Oates’s Sumi gaeshi that once again creates the opening for his arm tie roll.

Up against Ecuador’s Verdugo, he uses his Sangaku variation, hooking in with the right foot… It takes a couple of attempts… But he manages to get his opponent onto his back, and from that position he ties up the arm and secures the hold-down.

In the 2014 Abu Dhabi Grand Slam Oates pounces on a failed drop Seoi nage from Italy’s Verde. He moves almost immediately into the hold-down. Although it’s not his normal way of tying up the arm, you can see that the Sangaku legs leave no room for Verde to escape.

At the 2014 World Championships Oates produces a very fast Sangaku variation of his arm tie roll against Kim of the Democratic People’s Republic of Korea.

Once Kim is on his back Oates ties up the arm before moving into the hold.

At the 2014 Jeju Grand Prix Oates once again demonstrates the value of fast transition, as he’s straight onto a failed attack by Ukraine’s Iadov.

In one continuous movement he catches the arm, spins Iadov over, ties up the jacket and moves into Osaekomi.

In the final moments of the 2014 Baku Grand Slam Oates is a Wazari ahead against Russia’s Khan Magomedov. With Oates under pressure he uses Sumi gaeshi to bring the Russian into Newaza... He then catches the arm, turning his opponent, before moving in the opposite direction in order to start the hold-down.

As it’s not as tight as his standard variations, Khan Magomedov manages to get out of the hold. As a result, Oates scores a Yuko, but most importantly the clock has run down and Oates has won the contest and the Grand Slam gold medal.
