Solution Strategy
-
The positions of the center and the central
edge pieces never change. The central edge pieces may get
flipped over by 180 degrees, though.
-
First get the positions of the corners right without taking
any orientations into account. The corners will automatically
be oriented correctly.
-
If necessary, flip the central edge pieces over in pairs.
For instance, to flip the left and front central edge pieces
over, use L - F - L - F - L - F.
-
Done! With some practise, your average time should not be more than a few seconds.
