The canonical form of okuri-eri-jime refers to chokes where one lapel is held with the inside of the wrist against uke's neck, and the other is pulled taught to apply the strangle. The canonical kata-te-jime is applied using only one hand holding the collar applying pressure to the trachea with the outside of the wrist.
However I'm unsure how certain competitive chokes should be classified (e.g. clock choke, bow-and-arrow choke) - they are blood chokes using the inside of the wrist grabbing the lapel (like in okuri-eri-jime), but they are applied holding only one lapel (like kata-te-jime).
The kodokan considers jigoku-jime a variant fo okuri-eri-jime, which would seem to imply these other chokes are too, since they are mechanically similar.
How does the kodokan classify these techniques?
