What is a “beautiful maneuver”?—Since every maneuver has to result in a given operation, it is judged according to its performance, the primary requirement being effectiveness: The maneuver should produce its operation in the fewest possible layer moves. Middle layer moves, usually performed in two steps, are less “beautiful” than outer layer moves, and 180°-moves are less “beautiful” than 90°-moves. Since every maneuver must be stored in our brain and flow from our finger tips, a catchy and handy structure is desirable; in most cases this means moving as few layers as possible, and these layers should be easily accessible for right-handed people—without loss of generality.
