How to do Sode Tsurikomi Goshi
We'll start with two sleeves - the important thing is that we don't want our uke (partner/opponent) to be grabbing onto our lapels at all during:
- step to the top of the triangle
- your right arm pushes their sleeve across their face as we pivot through (we want our uke's left armpit on our shoulder)
- be sure your back is flat to their chest
- extend your legs to raise your off the ground and finish by throwing off to the corner at a 45 degree angle
Here's the Kodokan's version:
When should I use Sode Tsurikomi Goshi?
This move is best used when you have an opponent that has an established grip. You can use it against both righty and lefty opponents.
You'll see in the videos above you can grab onto the sleeve and as you're turning to start the throw you'll break their grips.
My best advice is to learn this in stages with uchikomis, throws on crash pad, then trying it in randori. Understand that you should do your best to execute this throw standing and not resort to drop Sode Tsurikomi Goshi in training.
This way, when it counts in tournaments, you can always resort to dropping to your knees to get under your opponent.
