Okuri-eri-jime Compilation. 

I remember when this was taught to me for the first time. I was the uke and my instructor kept me in a chokehold for good 30 seconds or more, while explaining how to hold the choke properly and what to do with the legs, (all the while I was tapping like crazy for him to let me go xD)

"Okuri Eri-Jime - strangulation" found on pg-123 of the Tao of jkd, amongst all the other judo, jiu-jitsu and wrestling techniques, in that chapter

Some of these are koshi jime and yoshiro koshi jime. Still impressive though, if you went to a bjj scho they'd charge you for this out of the nose.

amazing

That first one, who were the competitors?

1:54 what happens in that fight and why does the judoka in white react that way ???
