# JESSICA FRIDRICH ALGORITHMS PDF

Cubes were not immediately available to buy in communist Czechoslovakia, but Fridrich was able to acquire a Cube in July from a visiting French family. After learning a Layer by layer technique from a Czech magazine, Fridrich was averaging around 1 minute by September. The national championship took place in May by which time Fridrich was averaging about 25 seconds. Fridrich was one of five cubers who advanced into the finals, among them, Mirek Goljan. Fridrich won the first and second rounds and Goljan won the last third round.

Postage and Packaging What is Fridrich? Why the CFOP in the title? In particular, every speedcuber ranked in the top 10 by 3x3 average at any point since has used a variant of CFOP. All of the worlds best use a variant of this method, apart from selected few that uses Roux.

This could be done in less than 6 moves most of the time. More explained below. Your aim is to make all yellow sides face up. There are 57 algorithms. However, you only need to learn 7 algorithms to do this in 2 steps. You permute move the pieces on the last layer to solve the entire cube. There are 21 algorithms.

Cross This is completely intuitive, and is probably the hardest part in this method. Having said that, you can still with a bit of practice, see the best cross solution in 15 seconds and execute it in well under 3 seconds.

In fact, sub-2 cross is not even that hard. All cross can be solved in 7 moves, and a big majority of them only need 6 moves. However, you will need to spend a decent amount of time practising this step and the best way to do it is to solve it blindfolded.

Take as long as you want to plan out your cross and solve it blindfolded. You should now decide whether you want to be colour neutral or, well, not colour neutral. This is explained further in the link below. This is fairly intuitive and easy so you should find all four pairs this way. Now we solve both pieces at the same time. This is the major difference between F2L and Layer by layer. You can learn to do this intuitively, which is not as hard as it seems. Or you can use algorithms.

This is what 2-look is for. You solve a cross on top. Then you do the corners. This is highly recommended and you should learn this before you learn PLL. Do not feel you have to learn this straight away. Just take your time. I highly recommend learning this before you learn full OLL.

You can also do this in 2-Look.

## CFOP method

Orientation of the Last Layer complete The method consists of four steps: The Cross - This first stage involves solving the four edge pieces in one outer layer of the puzzle, centering around a commonly coloured centre piece. Many speedcubers usually solve the cross on the bottom side to avoid cube rotations, which slow down solve times. There are 42 standard cases for each corner-edge pair including the case where it is already solved. It can also be done intuitively.
