Rubik’s Speed-Cubing

Lars Petrus, the Swedish national speed-cubing champion, has a nice website on solving the Rubik’s Cube like a pro. There are a lot of Java animations that you can rotate with your mouse and play to show how each step of his method is done. His method involves solving the cube, not layers of the cube:

<q>Most people solve the cube layer by layer. This is a simple way for the human mind to approach the problem, but it is useless for speed cubing. No matter how good you are, you will use more than 100 moves. … The basic problem with the layer method is obvious, and very big. When you have completed the first layer, you can do nothing without breaking it up. So you break it, do something useful, then restore it. Break it, do something, restore it. Again and again. In a good solution you do something useful all the time. This layer is in the way of the solution, not a part of it.</q>
