Omoplata - is it legal in Judo?
Shoulder locks are forbidden in Judo competition so I was surprised when, flicking through Syd Hoare's book The A-Z of Judo, I came across ashi-sangaku-garami, which looks suspiciously like an omoplata to me.
Interestingly Hoare says "As the attacker leans forward so the pressure comes on the elbow joint". Eddie Bravo says of the omoplata (in Jiu Jitsu Unleashed) that "With a tremendous amount of pressure being placed on [the victim's]...shoulder, he is forced to tap."
My guess is that Hoare knows that ashi-sangaku-garami attacks the shoulder but nods it through as an elbow lock.
I couldn't find a definitive statement outlawing the omoplata in Judo competition but I did find a couple of posts on Judo forums that implied it was. Hoare's book was published in 1994 and it wasn't illegal then (banned techniques are shown but marked as being outlawed).
I couldn't get onto the IJF website to check there so I was wondering if anyone here had a definitive answer.
