No, that wasn't Petrus. Petrus doesn't use premoves. And getting a PLL skip would be lucky.Simple example: R (U' L' U) R' (U' L U)
Simplest example: M U2 M' U2
Also simple, but harder to find
(R' D2 R) U (R' D2 R) U'
(R' D2 R) U2 (R' D2 R) U2
(R' D2 R) U (R' D2 R) U'
etc
And you don't need insertions/commutators to get pretty decent results. I got my 33 move official solution before I even knew about insertions and commutators. Just be original and pause between every move you do. Don't blindly apply an alg you know.
But 30 moves with Fridrich seems impossible unless you get a really really lucky F2L, a short OLL and a PLL-skip. Same for Petrus, 30 moves only happens when you get very lucky.
I got 28 with a PLL skip (kind of worked for) with Petrus in one of the weekly competitons.
I just dugged it out....
Scramble: D' U2 L2 R' U' B' U R2 B2 D' R2 B' F2 D' L' B' U2 B' L' R' F2 D L2 D' R D U2 B2 F R B' F U L' R' U2 L D U' R' U2 R' F' L2 R2
Solution: L' D R B2 U' R2 F' B' U' B F2 y2 F' U' F U2 R U y' l F U ' F' R' F R U l' y R U' (28)
Explanation:
2x2x2: L' D R B2 U' R2 (6)
2x2x3: F' B' U' B F2 (11)
Pseudo F2L: y2 F' U' F U2 R U (17)
OLL: y' l F U' F' R' F R U l' y (26)
Undo Premove: R U' (28)
Maybe Petrus doesn't use premoves, but I do. Lucky is part of Petrus. And it took a few tries to get that LL.
EDIT: I just notice that I beat you that week....
