CFOP Quick-witted Princess Leia (Solve completing)

[Tito_H]

Episode XX
Princess Leia
was in trouble again.
She was in the commander’s
room in the Death Star, surrounded
by Darth Sidious, Darth Vader, Commander Tarkin, etc…

The Superlaser of the Death Star was aiming at the Earth.

Death Sidious said to Leia, “You could scarcely won the challenge last time. But I am pretty sure you will fail this time. I will not ask you if you accept this challenge, because that is the only option you have.”

He pulled a scrambled Rubik's cube out of his loose sleeve, and said, “I will destroy the Earth if you cannot solve this Rubik’s cube in 15 seconds.”

He added, “Hold the cube at the Yellow up and Blue front position, and don’t look at the left, back, or bottom face. The cube centers should be fixed. The Cross is already completed for you. To use the Force is strictly prohibited!”

She felt a little relief when she saw the cube, since it seemed not so complicated, and also it seems all edges are “good edges (solved EO)”, so OLL should be easier.

He handed the cube to her, and shouted, “Get started!”

But he was unfair, and just before she started to execute the first move, he said, “Oh, I almost forgot to tell you one more condition. The Blue-Red-White CP and the Blue-Red EP (UB) should not touch each other when they are not in their slot.”

He had known beforehand that she had a lack of knowledge of one technic in F2L which an intermediate level of cubers like her should have known.

Her face lost all composure, and she seemed to become increasingly anxious.

Can anyone kindly help her to save the Earth?

wha?

so no sexy then ZBLL?

Insert the edge into the correct position, then use a commutator to solve the corner. Something like this

 Setup 

L U' L' D2 L U L' R D2 R' D

 Moves 

x2 U2 R U' R' // insert edge
y' U D' R' D' R U' R' D R D // insert corner

Thanks for your response.
Sexy move violates the condition, because those CP & EP touch each other before slotted in.

L U' L' D2 L U L' R D2 R' D

 Moves 

x2 U2 R U' R' // insert edge
y' U D' R' D' R U' R' D R D // insert corner

Thanks.
Your set up + x2 is perfect, but there is one problem, although you’ve got the point.
y' move violates the condition, because the cube centers should be fixed.

Well you could exec without rotations, using different moves.

 

[pTr]

U2 R U' R' // insert edge
U [D' F' D' F, U'] // insert corner
U' // ZBLL set up
ZBLL-S(AS? I haven't learnt those subsets yet)

 

[Tito_H]

Thank you!

Year, you can convert the moves as follows to meet all the conditions, so all of you have just saved the Earth!

U2 R U' R' // insert edge
y' U D' R' D' R U' R' D R D // insert corner
⇩
U2 R U' R' // insert edge
U D' F’ D’ F U’ F’ D F D // insert corner
(… //OLL & PLL, or ZBLL)

But, I would like you to find a way to solve it by using only U, D, L, R slices, to be more ergonomic.

And one more thing.
Please use this.
U' R U2' R' // insert edge
There is a surprise.

U' R U2' R' // insert edge

Oh bet

 Setup 

L U' L' D2 L U L' R D2 R' D

 Moves 

x2 U' R U2 R' // insert edge
L D' L' U2 L D L' // solve

 

[Tito_H]

Congratulations!

(U2 should be moved as U2', to avoid contact between CP and EP.)

 

[Tito_H]

Now let me tell you what happened afterwards.

She immediately predicted that it would be impossible to slot in FR using only the U side and avoid contact between CP and EP. She then realized that a Keyhole method might be the solution, but she did not know how to do it when pairs were correctly slotted in the 3 slots other than FR.

So she quickly came up with a clever solution. First, she decided to move R U R' to slot it in. However, she only turned R halfway and then turned U with all her might. It’s that time the Blue-Red-White CP popped out of the cube and fell to the floor…

She said, "Oh, sorry," and meanwhile finished turning U R' without the CP, then inserted the CP she picked up into DFR position directly. In this way, she successfully completed F2L without the EP and CP coming into contact!

 

[Tito_H]

Princess Leia successfully completed the F2L and looked at Death Sidious with a triumphant expression, but he didn't look particularly surprised.

Princess Leia, on the other hand, looked troubled when she saw the shape of the OLL (U-U1-type). With less than five seconds remaining, OLL & PLL seemed insufficient, and she had no choice but to solve it in one go with ZBLL.

However, the algorithm that she knew was (R' U' R U' R' U2 R2 U' L' U R' U' L), and whether she rotated it as is or in the mirror sequence, the FR pair would slot out, violating the condition (the pairs must not touch).

What should she do?

Uhh do a D2 move before doing the ZBLL

 

[Tito_H]

You have just saved the Earth!
(D or D' is applicable as well.)

Thank goodness, I didn't know Leia was smart like that i wouldn't be able to find the solution
