Corners Correct, Edges Flipped
Note: there is also case 20 (O8) in the section No edges flipped correctly.
All Edges Flipped Correctly
For most of these cases, I instead use some COLL cases, which orients AND permutes the corners, so 1/12 of the time you will be left with a solved cube and the other 11/12 of the time you will be left with an easy (fast) cycle of edges.

---|---|---|---|
5 | (Rw' U2) (R U R' U Rw)
|
This is just a fat Antisune performed from the back of the cube. | |
6 | (Rw U2) (R' U' R U' Rw')
|
This is just a fat Antisune. |

Partial Edge Control
- Use
R' F R F'
(SL), instead ofU R U' R'
if no edge are correctly oriented. - For F2L case #35, use
R U R' U2 R U' R' U R U' R'
instead of usualF' U F U2' R U R'
to keep edge orientation.
Rules of thumb:
- Edges on U face always keep their orientation when doing only
U
andR
moves.
