There are 41 different variations for solving the corner-edge pieces in the F2L step. Many of these cases are very similar to each other (mirrors) and therefore. F2L Algorithms (First 2 Layers). Developed by Feliks Zemdegs and Andy Klise. Images sourced from Conrad Rider’s VisualCube. The CFOP Method (Cross – F2L – OLL – PLL), sometimes known as the Fridrich method, is one of the most commonly used methods in speedsolving a 3×3×3.

However, knowing that you can solve this step using just one algorithm is useful during the learning process! The strategy here is to join a corner of the first layer with the edge that goes above it, then insert that pair. This completes the cube, feidrich you probably know looks like this:.

## Speedcubing Guide

Even if you understand the basic ideas above, it isn’t always obvious how best to proceed. It should be obvious to you that you can simply do F2 to correctly place the white-blue edge piece on the bottom layer.

F2L Information Proposer s: This step was proposed by Hans Dockhorn and Anneke Treep. At this stage, a lot of people still find it quite difficult to intuitively manipulate the cube. However, many other sites do have so-called “algorithms” for this step.

### CFOP Method – Wikipedia

Case 5 Corner on Top, Edge in Middle. From Wikipedia, the free encyclopedia. Twisty Puzzles Online Stores International. By using this site, you agree to the Terms of Use firdrich Privacy Policy. This leaves you with a very start-stop, stuttery solve as you rapidly perform an algorithm and then stop to find the next one. From Wikibooks, open books for an open world. Now that you know the beginner method, you can begin to introduce the concepts in this guide into your solves.

If you can intuitively solve every F2L situation you come across then jolly well done, but there are a few cases where there is just a better, faster, f2, less obvious algorithm to solve it. As mentioned above, the sections in this method don’t have to be learned sequentially. A trigger is simply a sequence of moves that is fridricn to perform very quickly, and the Sexy Move trigger comes up a lot.

I have not had time to make sure all these moves are correct. Why don’t you give it a try – go to the timer pageset inspection time to 15 seconds and see if you can produce a solution to the cross entirely in your head. Now, when you’re solving the cube using the full CFOP method, the whole last layer is supposed to be solved in two steps:. You might think that this sounds quite challenging, and you’d be right.

You have two options here. Wiki tools Special pages. This means that doing the cross on the bottom is difficult, as they have come to rely on algorithms for situations that are suddenly upside-down.

The idea of F2L is to pair each of the four bottom layer corners with the corresponding edge piece and then insert them into the correct place. Czech speedcuber Jessica Fridrich is generally credited for popularizing it by publishing it online in If you perform each algorithm as quickly as humanly possible, you don’t leave yourself much time to analyse the cube and isolate the next corner-edge pair you want to solve.

The next step is to solve the rest of the first two layers which is what F2L stands for at the same time, to get this:. Being able to recognise it and perform it without thinking will make the task of learning lots of algorithms much, much easier. Here’s a simple example:. COLL and CLL both mean different things to other cubers, and sticking to convention makes things a lot easier for everyone involved.

Full CFOP takes some dedication. Of course, when you’re just sat at home on a lazy Sunday idling the afternoon away with a Rubik’s Cube you likely won’t be paying much attention to official WCA competition rules, but it does give you something to aim for.

If you only have one, then which algorithm you use depends on the direction that the other edges need to be cycled. After solving the cross, a corner-edge pair is paired up form pairand then inserted into the correct slot pair insertion. The first algorithm either requires you to shift your hand position to twist the F face or start using some peculiar thumb movements. But not exactly the same, as you’ll have noticed – the cube is upside down. It is recommended that you should start learning using the beginner method first, then use the Fridrich method once you have become proficient at that.

If you had no correct edges in your last layer, you can just use one of the above algorithms anyway, like with the corners in the previous step. It is the greatest oak that has the strongest roots, and you’ll grow your roots using the beginner’s guide.

It does take time to get used to, and it doesn’t really matter how long you take when you’re practising. This method was first developed in the early s combining innovations by a number of speed cubers.
