Kim Gwang Suk (PRK) allegedly
So this one’s a fun little mystery. It’s theoretically named after Kim Gwang Suk in the code of points, just like the giant-swing counter-Kim that she made famous, although it is listed as “TBC.” That’s ostensibly because…we’re not really sure if she did it? I’ve never seen video of Kim performing a toe-on version at a worlds or Olympics (or ever), just the regular type. The world may never know.
That doesn’t mean it has gone completely unperformed, though. Every once in a while a gymnast will show up in the JO program in the US doing a counter-Kim, and in their cases it’s almost always the toe-on version.
