CFOP is the most frequently used speedsolving method for the 3x3x3 cube. It is also known as the Fridrich Method after its popularizer, Jessica Fridrich. In part due to Fridrich's publication of the method on her website in , CFOP has been the most dominant 3x3 speedcubing method since around , with it and its variants used by the vast majority of the top speedcubers such as Feliks Zemdegs , Max Park , Sebastian Weyer , Mats Valk , etc. In reality, many developments were made in the early '80s by other cubers who have contributed to the method in its current form. The constituent techniques and their original proposers are as follows:. During the resurgence in speedcubing's popularity in the late '90s and early s, there was a general lack of information on the sport.

Since then the methods have evolved and we are capable of reaching solution times below 6 seconds. If you want to improve your cubing speed, all you need is a high quality , well lubricated Rubik's Cube with good corner cutting and optimal tensioning so the pieces don't pop. Practice finger tricks , the art of turning the cube like you can barely see the movements. You'll also need a Rubik's Cube timer to keep track of your evolution, and a lot of practice of the method described in the tutorial below.
When talking about the advanced technique of solving the Rubik's Cube we have to mention the Petrus system and the Fridrich method or full CFOP which is used by the big majority of speedcubers these days.
This advanced technique developed by Jessica Fridrich divides the puzzle into layers and you have to solve the cube layer by layer using algorithms in each step , not messing up the pieces already in place.
The method developed by Jessica Fridrich involves memorizing a lot of algorithms, but there is a logical connection between them. After a lot of practice you will develop the ability to execute these operations intuitively. First of all we have to solve the white edge pieces in the bottom. This seems to be the easiest but it's really hard if you want to do it right. You should be able to determine all the rotations needed to complete the white cross after inspecting the cube, and you'll succeed only if you foresee 7 steps.
When the cross is done we solve the first two layers F2L in one step using a technique to pair the white corner and second layer edge pieces. We are talking about four corner blocks which usually require 4x7 steps.
Orienting the last layer OLL of the Rubik's Cube is the step in which we solve the yellow face without matching the side colours. We are going to position them in the next step. Learn all the 57 algorithms to complete this step. Permutate the last layer PLL to finish the solution of your cube.
There are 21 algorithms to memorize. First step. Steps of the Fridrich Rubik's Cube Method : 1. White cross 2. First two layers F2L 3. Orient last layer OLL 4. Permute last layer PLL.

How to Solve the Rubik's Cube/CFOP
You want to learn the Fridrich but do you own a decent cube? I would advice you to get the MoYu Aolong v2, best speed cube ever! Fridrich method : Advanced solution for Rubik's cube 3x3. We are now going to have a look at the Fridrich method.
Rubik's Cube solution with advanced Fridrich (CFOP) method
The first two layers F2L of the Rubik's Cube are solved simultaneously rather than individually, reducing the solve time considerably. In the second step of the Fridrich method we solve the four white corner pieces and the middle layer edges attached to them. The 41 possible cases in this step can be solved intuitively but it's useful to have a table of algorithms printed on your desk for guidance. To be efficient try not to turn your cube around while solving and look ahead as much as possible. Familiarize with the algorithms so you can do them even with your eyes closed. In the beginner's method solving the white corners and the second layer edges were two separate steps, but in this stage you should already know this.
Step 2: First two layers - F2L
This method was first developed in the early s combining innovations by a number of speed cubers. Czech speedcuber and the namesake of the method Jessica Fridrich is generally credited for popularizing it by publishing it online in The method works on a layer-by-layer system, first solving a cross typically on the bottom, continuing to solve the first two layers F2L , orienting the last layer OLL , and finally permuting the last layer PLL. Basic layer-by-layer methods were among the first to arise during the early s cube craze. David Singmaster published a layer-based solution in which proposed the use of a cross. The major innovation of CFOP over beginner methods is its use of F2L, which solves the first two layers simultaneously. This step was not invented by Jessica Fridrich.
