Round-off 1/2 on, front tuck
Yurchenko 1/2 on, front tuck
Natalia Ivantcheva (BUL)
Undervalued with respect to the typical Yurchenkos, the Ivantcheva is almost never seen these days—in either elite or NCAA—because it’s just not worth even bothering with a round-off 1/2 on entry unless you’re an elite planning to eventually upgrade to a Cheng, or you’re an NCAA athlete who can pike it because the tuck does not start from 10.0.
You will often hear round-off 1/2-on style vaults referred to as “Yurchenko 1/2 on,” which is fine, though I don’t use it. The term Yurchenko refers to the round-off vault entry without any twisting in pre-flight—vault group 4. When a half-twist is added, it becomes a different entry, that isn’t a Yurchenko. Yurchenko is not a synonym for round-off. It’s a style of vault, of which this is not one.
The valid counter-argument to that would be that using Yurchenko 1/2 on is no different than referring to a skill as a Shaposhnikova 1/2, even though the Shaposhnikova is its own different, specific skill. Which is a good point. Other counter-argument: the round-off 1/1-on vaults are classified in the same family as the Yurchenkos, so why shouldn’t the round-off-1/2 on vaults be as well? Also a good point. So basically whatever.
