Chance,
Attack the arm that reaches over your back. Or you can overhook the choking hand.
His left hand reaches across the front and goes for your lapel...
You overhook and pin it with your left armpit...
You have to rotate underneath him over 180% clockwise in this case...
(You have to keep him from turning with you)
You essentially come out the side door into wakigatame...you may have to grab his left leg with your right hand to prevent his escape.
You can use the armlock to set up the sweep/turnover.
For instance, you may nearly come out side door for the armlock, but he finally spins and catches up. You can go for the turnover. Might I suggest the blueberry? Very tasty.
But seriously, If you get good at the grip, spin, and feel for the balance, you can let go one arm, and take the other, back and forth. Of course, as you can see from the tape, you can easily get guard back during the scamble, as you have created some space by his having to defend.
I think I remember some BTT guys trying it off a failed shot. It works that way too.
He sprawls, puts at least one arm across your armpit, you pin, spin and win. Celebrate with gin. Hopefully, you can do it agin. Aaaahh! See what you made me do?
(Terrible, just terrible lol)
Sorry for the ramble. There must be some video somewhere. It is only moderately advanced judo that I was describing.
See Ya
