(stupid qqtimer scramble)
Double x-cross: x2 y D R U R' F2 U2 R2
f2l1: U’ R U’ R’ U R
f2l2: y’ R U’ R’ U R U R’
COLL → EPLL skip: y2 R’ U R2 D r’ U2 r D’ R2’ U’ R

can someone find a better solution?

[mycube]

found a solution with a LL-Skip. But you can't do this in a speedsolve:

x2 y D R U R' L F2 L' - pseudocross
F R' F R' F' U' F' D2 B U' B' D2 - TXCross
U L' U R' U L U' R U2 L' U2 L U - F2L-Pair4 + forced LL-Skip
=41 Moves

Crazy Scramble...

Crazy start: D R F' R' F U D R2

5 corners: F D F D' F2

optimal insertion bring 7 move cancelation --> 22

Or crazy finish: D F2 D' U R F2 R' F2 U' F R F' R'

--> 21 moves

Here're the scrambles of PKU FM 2012.

1. R2 B D2 B' D2 F2 L' U R2 F' D' R' D' R2 B' R2 F2 U B2
2. L B2 R2 U2 F2 R2 D' F' R U' B2 U2 L' B' U L D2 F2
3. B2 F' D2 L2 R2 F2 D2 L2 B D2 F' D' B' U2 R' B2 D2 B D'

I luckily got a solution of 25 moves and broke the AsR in the first try. The following is my solution:

222: F2 L B' R' F
Inverse it and go on building block:
B L' D' L2 B2 D' B' D' L D L D' B D
Remained 3 corners:
D' L U' L ' D L U L'
Final solution:
F2 L B' R' F L U' L' D' L U L' B' D L' D' L' D B D B2 L2 D L B'

doesnt work for me with the scramblie you provided.

Edit: Taking the inverse of your solution as scramble your insertion is optimal. Did you search within the whole skeleton?

Sorry I mixed the scrambles. The first two should be exchange. I've corrected them now.

When I found the skeleton, there's only about 10mins to find the insertions and obvious the insertion canceled 2 moves so I wrote the solution down immediately. After that I tried to find a better insertion but failed. In fact, I used the Insertion Finder to search the optimal insertion and found out it's the same as mine.

B' U R U B2 R B U' L' D L2 D R2 B2 D R2 L2 B2 U'

. F L , U' B U2 B' R' U2 F2 U' // 2x2x3 (10/10)
R D2 B' D R' D R B D' // F2L (19/19)
F' U F D' F' U' F D R // L3E (28/28)

Insert B' R2 B F' U2 F @ "." to cancel 1 move.

At this point I ran out of time, but soon after I found a 3-corner insertion to replace the underlined moves: insert L' D R D' L D R' D' @ "," to cancel 2 moves.


Final solution: B' R2 B F' U2 F2 L U' B U2 B' R' U2 F2 U' R D2 B' D R' D R B D' F' U F D' F' U' F D R (33 HTM)

With extra insertion: B' R2 B F' U2 F2 D R D' L D R' D' U' B U2 B' R' U2 F2 U' R D2 B' D R' D R B D' R (31 HTM)

First attempt on THIS scramble got me a 30 FMC.
D' L2 B2 D' L2 U R2 D2 L2 F2 R' B U F' L2 U' B2 U R' U2

y F2 R' F' R2 B L' // Rouxblock [6]
U D F U2 x2 // 2x2x3 [4/10]
y' R' F R F' R U2 R' U' R // EOF2L [9/19]
y R U2 R' U2 L' U R U' R' L // COLL [10/29]
U // EPLL [1/30]

Took about five minutes. Almost linear.

I might sound noobish... but what's a skeleton? I looked around the forums and I still have no clue.

This was one of my solves off the example solve thread.
