Round-off 1/2 on, tuck full
Yurchenko 1/2 on, tuck 1/1
Put this one in the category of “if you’re talented enough to do this vault, you’re probably doing a piked or layout vault with less twisting that’s worth more. In this case, the pike 1/2 is worth more than the tuck 1/1, so only the gymnasts most comfortable with forward-landing tucked skills (not a lot of them) will even bother with this one.
This is also one of the rare vaults in the round-off 1/2 on family that is not named (either formally or informally—we’ll get to that with the others) after someone.
