To me, with any aiki art, one of the biggest issues occurs when this kind of recovery isn't discussed. That both takes away a range of responses that work really well with the overall movements, and also incorporates the working assumption that the techniques don't fail except in ways that lead to other "open" techniques (those that are done at elbow distance or further). Not having these tools (and using that assumption) means there's not much way to do resistive partner training.Interesting, I have always heard it called a reinforced underhook, not the beef wellington but yes, I would argue this goes like PB&J with Aikido, its the same principle and I was taught and have taught it as a reaction to a resisted Kaeten Nage (rotary throw), although I was told it was a wrestling move not an Aikido one.
