今天尝试了一下，确实很有难度。拿笔记下了每个步骤，最后还是计算错了。相信对训练方向感很有帮助。 Chris Hardwick的两个例子。借来参考 ：）
First attempt 12/16/02
Took 3 hours 14 minutes 50 seconds total. Here's cube explorer's move to get to the scramble I had:U F2 U L2 D F2 B' L2 U' B' L2 R' F L2 B R D U2 R2 Here was my solution: *first and only look*
(cross) D2 F' R' L' D F B
(BR pair accidently placed incorrectly) R U R2 U2 R
(FL pair) F U' F' L' U2 L
(BL pair) R U2 R' L U' L'
(place FR corner and BR edge into FR) U' R U2 R2 F R F'
(fix BR and FR) R2 U2 R2 U2 R2
(orientation case) L F R U2 R' U2 R U2 R' F' L'
(permutation case) (U) L2 B2 L' F' L B2 L' F L'
= 57 moves
Second attempt 5/6/04
Took 1 hour 54 minutes 24 seconds total. I did this for the 5/2/04 Sunday blindfold contest. Here was the scramble:B' F' D' F' B L' U2 F L2 B' R L F2 U' D' B' U B L2 D2 L' U2 B' R2 F Here was my solution: *first and only look*
(Double extended cross) L' R D2 L' F' U D' L B'
(FL pair) U B' U' B F U F'
(BL pair) U' L U L' U B' U' B
(OLL) U2 R' U2 R2 B' R' B R' U2 R
(PLL) B2 R' U' R B2 L' D L' D' L2
= 44 moves
