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.

Although it requires you to memorise many up to 78 different algorithms, it’s one of the fastest speedcubing methods.
At this pace, you remove the temptation to focus only on the pieces that you are currently applying an algorithm to, and you can easily be looking at the rest of the cube to find the next F2L pair. Using this algorithm is preferable than using the first algorithm twice, as it will be much faster to perform. Mostly, people learn 1-look PLL before 1-look OLL, as there are fewer of them to learn and they are more easily identified.
Here’s a similar example:. If you need to swap opposite edges, you can use this algorithm:. Your natural instinct may be to use your right hand, which produces the first algorithm.
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. It takes practise, and the next little section is all about how to be better at F2L.

Indeed, the whole cross is assembled on the bottom layer instead of the top. In the diagrams of the fririch made with Lars Vandenbergh’s amazing ImageCube scriptonly three sides can be shown, so sometimes, stickers from the edge cubie will be hidden from view. It’s all very well and good being able to perform algorithms quickly, but perhaps the most important thing with F2L is to perform the algorithms continuously.
Being able to recognise it and perform it without thinking will make the task of learning lots of algorithms much, much easier. Page last modified on Jan 18, This database is part of the speedsolving. The important part of F2L is being able to solve each of the pairs without affecting any of the other previously solved pairs. The only pairs that needs both R and F turns are the six ones with the edge unoriented in the slot, if the edge is oriented in the slot both fgidrich works.
First Two Layers
You have two options here. SpeedsolvingFMC Previous state: I have gone through each of these situations and chosen algorithms that I think are easy to both perform and learn, but you may feel differently. Now that you know the beginner method, you can begin to introduce the concepts in this guide into your f2k.
As you practise incorporating the techniques on this page into your solves, you will learn to recognise the various other OLL and PLL situations, f22l will help immensely in their memorisation. This page was last edited on 17 Decemberat For example, consider the following two algorithms:. Please help improve this section by adding citations to reliable sources.

In the following fidrich, you can see that the ‘headlights’ are on the Front face, as the top layer corners are both blue. These dridrich techniques can help you improve your speed in the step.
There are, however, some more optimal algorithms. Both have the same effect, but a double layer turn is quicker. As mentioned above, the sections in this method don’t have to be learned sequentially. This idea of finding an empty space on the cube and using it to build a corner-edge pair is crucial to F2L, as of course you want to be able to construct each of the four F2L pairs without disturbing any previously solved ones.
I shall now try to explain some further concepts that you can use to improve your F2L. Going slowly isn’t better – going faster is better, but you’ll get faster by going slower.
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:. This doesn’t disturb any of the other F2L spaces, but you can see that the red-green pieces are looking frierich unsolved and unhappy. COLL and CLL both mean different things to other cubers, and sticking to convention makes things a lot easier for everyone involved. If you do UF’U2, you can turn this case into case 2 above.
