Neck shock... christ on a pogo stick.
Case in point
If your opponent has thrown the arm over the top and secured a deep grip, the absolute last thing you want to do is try and attack with an O soto. You should be posting the shoulder, shoulder rolling and trying to regain your posture.
I've written about the flawed mentality of the 'set up' so many times it makes my fingers ache. I know many coaches view it as useful way of simplifying the principle of action re-action, but really it does more harm than good. It's like using the stalk to explain where babies come from to high schoolers.
You can use movement and ashiwaza and other things to help create opportunities, but all those things do is to try and give you a leg up on the real skill, which is timing.
Timing is the ultimate 'set-up', because you don't have to do something you just react when an opponent makes a mistake.
Annoying thing about timing is that it's a pig to learn. It takes time, lots of randori, lots of quality instruction and above all lots of failure and frustration before you get it down.
This video of Komuro is a good example, the only time he uses 'set-ups' as espoused by the Anglo-phone Judo community is when he's dicking about with white belts. The rest of the time it's pure timing.
That last vid, judoka_uk, is some of the finest judo I've seen on the internet. Thanks for the heads-up.
^ what the fellow above me said, that was astonishing!!
I'm a bit late to this thread, I see judoka-Uk put in the good word on "set ups", so I 'll leave that alone other than to say I used to fall into the same "set up" trap.
How "good" is your Harai Goshi? Can you do it well with a compliant uke, moving in different directions, in ai and kenka yotsu situations?
If so, not so much in the way of "set ups" are needed. Rather, you movement and attacks with ashi waza (or the combination of thereof) will usually get the job done.
That said, I often attack with a driving Kouchi Gari (in a right vs right gripping scenario), and if they step off/back, can fit into Harai Goshi (or just about any other forward throw) pretty well.
The key is as JUK noted, lots of randori, quality instruction, and quality training with a lot of nagekomi (throwing). It takes a good long while because there are many elements.
Komura is amazing. He is much more of an ideal judoka to me than most of the world champions and elite level players who get more press because of their high level accomplishments in competition.
Everytime someone tries some sort of weird grip on him, he uses it against them. And he does it against guys of his own rank and much larger judoka.
The way he dominates the opposition isn't too dissimilar to the way my coach demolished his opponents in that video I sent you a while back, as you said, a shark in a .... tank.
Put Komuro against Inoue and we know who would win, put Inoue up against the amateur opponents Komuro faces and we'd see similar fireworks to Komuro.
He's doing his Judo against guys his size and larger (other than working on the kids/white belts), in shiai (kodokan high dan shiai in one case?), so they are not slouches at all. And doing some damned nice Judo at that. There are gradations of skill even among "mortals".
Great thoughts, folks. Thanks.
And yes, I don't really have a clue. That's why I asked. But this helps.
