Watch my super fast 7. Reviewing the best speedcubes in the world and where to get them. There are 57 different OLL variations, therefore needed 57 different algorithms to learn in order to complete the OLL step in just 1 algorithm. The algorithms are divided into groups based on the "shapes" they form on the U face. I had Bolded the algorithms that I use in my solving, which I find easiest for me.

In this step 4 F2L pairs are inserted into their correct positions thus completing the first two layers. Theory F2L is an incredibly important step of the Fridrich method that can be done intuitively without the use of algorithms. It takes a while to master, but when you eventually to get into it, it will decrease your times significantly. There are 41 basic cases that you can run into if you only consider a single pair and assume everything else to be solved.
See the links section at the bottom for all cases and how to solve them. Basic rules when solving F2L: Cube Rotations are to be avoided as much as possible. As a beginner you will find this hard, but try going towards reducing cube rotations to maximum of about each solve.
Maximize lookahead as much as possible! This is very important. During your practice sessions, try going slow and try to look ahead as much as you possibly can. Here is my response: You should absolutely learn F2L intuitively. That being said, there are a few cases that are worth learning because their quick algorithmic solution turns out to be much quicker than the one you would get if you tried to approach it intuitively.
For these few cases, I recommend learning algorithm to solve them. The notion of "intuitive" is very different for every person, but here are the basic cases that I learned algorithms for: basically mostly those cases where corner and edge are somehow connected are good candidates for memorizing.
But I would encourage you to only use the page to get inspiration. Note that these are not required for you to get extremely fast. I know people that average in aseconds and they barely use of this stuff. Instead they just turn very fast and have an extremely good look ahead. Reducing of cube rotations This is an important part of getting faster.
Many times you want to insert into a slot other than the one in front of you FR slot. Sometimes you want to insert to the back, or the left, etc. It is very important that you try and find good ways of doing these insertions without making a cube rotation Even though in some cases it is inevitable. Other times you may run into a case where you paired up a corner and the edge but the slot that you want to insert it into is not in a very convenient position.
This took out a pair. How would you solve this pair? It is not always the best choice to use that insertion, but often times it is. These open slots give you additional degrees of freedom that you can and should use to your advantage. Check out that difference! When you see this during your F2L solve you should either try really hard to pop it out quickly and hope that it breaks up, or you can try to handle it right away while many of your slots are open.
Remeber this trick, it can be useful. Stuck pieces Many many times you will find that corner and edge are not to be found on top, but are instead stuck in random wrong slots. It is often possible to join these pieces in some clever quick way that is usually still quite intuitive, but sometimes needs pointing out.
Check out this genious incredibly fast solution to the first case on the right. You are trying to solve the FR slot, but the edge is stuck in the back, and even in the wrong orientation! So if you move the corner on top of it, the pair is dissaligned. What a dissaster! I bet you stumbled by that case at some point and cursed, because its a pain to solve intuitively. The edge is on the left in the wrong slot, and the corner is solved. These are just examples, there are many many more cases you should look into.
Check the links for the specific websites. Multi-slotting Multi-slotting is a technique in which while inserting one pair you try to set up an easy insertion for a second pair. So in a sense you are attempting to solve two pairs at the same time, or at least make the second insertion very easy.
The following example illustrates what multislotting is about. See what happened? Not only did you solve the first pair, but you also paired up the second pair! Its ready for an extremely quick insertion now. I personally do not use multislotting because I am of the opinion that it does not provide benefit unless studied extensively. It also requires you to see way too many things around the cube, and is without a doubt the most advanced technique for F2L.
Make up your own mind on whether or not you want to look into it, and do let me know of the result if you decide to try it. As you can verify for yourself, most of the OLL cases where all the edges are already correctly oriented are very easy to solve.
You apply partial edge control while you solve the last pair, and solve the edge orientation as you insert it. This will orient all edges and insert that pair. F2L usually works by reducing to these two cases.
There is yet another approach to control edge orientation. It requires no algorithms that you need to learn, but is a little bit riskier. It uses the fact that if you only turn two faces of the cube such as U and R , you can never un-orient an edge. Petrus method uses this property in a very clever way. What you need to do is solve two adjacent F2L pairs, and then orient all edges on the cube while it is still easy, because you still have a lot of freedom in what you move.
Check details on how to orient edges in this way from Petrus website. Speedcubing Advanced F2L page has a few very nice solutions to some cases, mostly Stuck Pieces cases.

In this step 4 edges have to be solved to their correct positions. Theory Take a look at the graph on the right. It shows the number of moves that you need to make to solve a white cross. Most interesting is the fact that most of the time the cross can be solved in 6 or less moves. Color Choice The most often chosen side to make a cross on, by convention, is white.
FIRST TWO LAYERS (F2L)
Here is my attempt to order them at least approximately based on when you should watch them, and some helpful links. Name is badmephisto - If you get stuck with notation, check notation page Speedcubing world Once you solve the cube yourself at least once even if you are still looking up the algorithms , check my intro to speedcubing video. This is helpful and good. Register on the speedsolving forums : best way to meet other speedcubers and ask questions. If you want to get yourself a better cube or ask about lubrication, check the Hardware section of the forum. These people know a lot about cubes, and which ones are best at any time.
A: Follow the Guide also link on left I put together. It orders all of my YouTube videos in the sequence I think they should be watched. Q: Where should I get a cube? Q: Cool, then what?
