Now let’s take a look and analyse how Dragin executed his different Sumi Gaeshi variations at the World’s biggest tournaments.

Up against Millar of Great Britain at the 2009 Paris Grand Slam, Dragin circles around disrupting his opponents balance, then attacks with his Sumi Gaeshi.

The circle Dragin creates, pulls Millar down onto one knee. As soon as the knee hits the ground he starts the execution of the attack.

In this variation Dragin is on the sleeve but ends up with a grip around the waist rather than on the lapel. This changes the final stage of his execution. He isn’t able to pull down on the lapel into his body to help with the rotation, which results in him narrowly missing the score.

In the Final at the 2009 Paris Grand Slam, Dragin was up against Georgia’s Amiran Papinashvili. With a minute remaining on the clock and a Waza-ari a piece Dragin makes his move.

With Papinashvili being in a low bent over position, Dragin uses his variation for a defensive opponent.

He initially does the foot stamp but doesn't get much of a reaction, he lets the Georgian settle and then does it again, this time really opening him up.

He shifts his weight backwards, pulling Papinashvili on, throwing himself right underneath his opponent. A good hook and strong flick sends him over.

Due to Dragins grip high up on the sleeve, the Georgian is able to get his hand down to cartwheel off, avoiding the bigger score. But the attack gave him the decisive Yuko, and the title.

The following year in the Quarter Final at the 2010 Paris Grand Slam, Dragin goes to execute his Sumi Gaeshi on Burjan, but the Hungarian reacts looking to execute his own. The result is a different variation of Dragin’s Sumi Gaeshi.

Starting on the sleeve, then taking a dominant grip over the top of his opponent, Dragin steps around to the side, to the square position. Then he shifts his body weight backwards. At the same time Burjan lifts his left leg, to attack with his own Sumi Gaeshi.

Dragin reacts instantly to his opponent’s movement, going down onto his back, rotating to his side, using his left leg to really flick Uke in the desired direction.

The arms play a very big role in completing the attack. The grip around the back really lets Dragin rotate the Hungarian off to the side, while the sleeve arm helps guide him onto his back.

Against Min-Ho Choi in the Quarter-final of the 2010 Dusseldorf Grand Slam, Dragin attempts his Sumi Gaeshi off of the Koreans failed drop Tai otoshi attack.

But doesn’t quite get the flick and rotation needed to score.

However when they next meet at the 2012 Prague World Cup, Dragin succeeds. This time it was off Choi’s failed drop Seoi Nage attempt in the first exchange of the fight.

Dragin reacts, circling out of the way, of the Seoi attack, until he ends up in front of the Korean. He start’s shifting his weight backwards as soon as he’s there. He drops down making a good connection with the right shin, hooking with the foot. Then he flicks and rotates with the arms.

Dragin came incredible close to scoring on Uzbekistan’s Rishod Sobirov at the 2013 Paris Grand Slam with his twitch Sumi Gaeshi variation.

Starting with the twitch Dragin doesn’t quite get the reaction he needs, so instead he circles around in front of Sobirov to get to the square position.

As soon as he circles, the right leg comes up to make contact. But Sobriov shifts his weight to Dragin’s left, making it hard to get the rotation needed with the arms to send the Uzbek over for the score.

At the 2013 European Championships, Dragin demonstrates that if you fully commit to throwing yourself underneath your opponent you can still score, even if you miss the contact with the leg.

He gets the initial reaction from his Hungarian opponent Gorjanacz by doing an almost back step twitch. He shifts his weight backwards straight away before throwing himself right underneath his opponent.

Somehow Dragin’s right leg ends up on the outside of the Gorjanacz, but the momentum he has built up and the use of his arms, ensures he can send the Hungarian over for Ippon.

Against Zantaraia at the 2013 Samsung Grand Prix, Dragin attempt numerous variations of his Sumi Gaeshi on the Ukrainian, but due to Zantaraia’s unique acrobatic skills he isn’t able to score. The first was off the foot stamp on a defensive opponent. The second was off a side back step and the third came from a twitch set up

The following contest saw Dragin execute this brilliant examples of his twitch variation against Azerbaijanis Shikhalizada.

The twitch really unsettles Shikhalizada’s balance, a little skip to the side and Dragin shifts his weight backwards, lowering to the mat. The leg comes up and flicks, strong rotation on the lapel and it’s all over. An excellent example of just how effective this technique really can be.
