Yurchenko tuck full
Yurchenko 1/1 tucked
While the Yurchenko tucked is the first Yurchenko vault listed in the code of points and is the one named after Yurchenko, there are two original Yurchenkos from when she debuted the skill domestically in 1982 (seen above)—the layout, and the tuck with a full twist. These are the classic Yurchenkos.
When this vault took the world by storm, the layout version quickly became the expectation, and that holds true today. A straight layout with no twisting is worth more than the tuck with a full twist, rendering the tuck full almost entirely unnecessary and disappeared.
