Here double European medallist Colin Oates demonstrates the standard variation of his arm tie roll from start to finish.

Oates says that a great way to initiate the roll is by pulling through your partner on the sleeve and then chopping them down.

As a result, they are likely to land on all-fours, which means there is space in which to catch their wrist.

The catch must be immediate… Once on the wrist, Oates tucks their arm into their own stomach.

He then circles around the top half of their body, prising out their arm.

He says that at this point the partner will usually have flattened out, and as a result will feel that they are safe.

So, he stays very calm, with a clear focus of tying up their arm using their own jacket. At the moment that Uke feels under real threat they will panic and try everything to escape. This is why Oates doesn’t roll them until after he has tied up the jacket.

He then drops his bodyweight down onto his partner’s shoulder, grips their far lapel, and rolls them onto their back.

A few key points here; the entry for the catch comes from under their armpit.

Here, uke lifts up to show the contact between the arm and the stomach.

When tying up the arm, you feed the jacket from the bottom of the skirt, taking in as much material into the hand as possible.

So from the chop down, you can see that Oates is onto the wrist as they land... Once he’s at the head end he rotates his wrist in order to feed the jacket into his hand… He then secures the arm, takes the far lapel with his left hand , and moves into Oasekomi.
