Thanks, but I believe there is a misunderstanding. I know what a Counter-Kim is. From memory, aside from Kim Gwang-Suk, I recall Gogean, Bégué and Hategan performing one. I'm sure I'm forgetting a few gymnasts. But that wasn't the skill I was describing. I was thinking of a Tkatchev with a flip, or, if you prefer, a Counter-Kim caught on the same side of the bar than a Tkatchev (assuming the preceding giant goes in the same direction). I guess that no answer must mean that it hasn't been done yet.
