CFCE method
ELL.png
Information about the method
Proposer(s): Guus Razoux Schultz
Proposed: 1981
Alt Names: CLL/ELL
Variants: OLL/PLL
No. Steps: 4
No. Algs: 71 to 112
F2L:0 to 41
LL: 71 (CLL: 42; ELL: 29)
Avg Moves: 54
Purpose(s):


CFCE; Cross, F2L, CLL and ELL, a LBL where the first two layers are solved simultaneously by forming a cross and then fill in the F2L slots with pairs. The last layer is solved in two looks, first all the corners are done in the CLL step and then, for completion, all the edges in the ELL step.

The Steps

1. Cross

First, make a cross on any side of the cube. This entails solving all of the edges with a given color to their proper positions.

2. F2L (First Two Layers)

In this step you fill in the slots where the corners of the cross are missing. For each insertion, a corner and an edge are placed simultaneously. There are 41 basic cases for this step, but it can be learned intuitively.

3. CLL (Corners of the Last Layer)

Next, solve all last layer corners in one of 42 algorithms.

4. ELL (Edges of the Last Layer)

Finally, you finish the cube by solving all the last layer edges. There are 29 algorithms.

History

Guus Razoux Schultz used the full method in the 1982 world championship finals, where he got second place. In the early 2000s Masayuki Akimoto adopted the method and set the first Asian 3x3 single record of 17.79s at the 2003 world championship.

Since then, CFCE adoption has been hampered by the dubious belief that last-layer recognition is harder for CFCE than for CFOP, and that the ELL algorithms are bad. However recent years have seen renewed interest in the method.
