This is a well known trick. all the guides have it.

ok thank you,maybe i should read all the guides before posting from now on

Rotationless F2L technique

I'm working on working rotationless F2L into my solves (CFOP) with the exception of x' turns to set up and insert back pairs. Having a great deal of trouble looking ahead with pieces in the back and some cases where I use Front face and Back face turns because i'm still trying to find fingertricks that work well for me.

Any suggestions on how to lookahead in the back without x' and efficient fingering for front and back?

Use your left and right hands you L, R and U turns if you didn't already.
L is better than doing a cube rotation then using R.
Also, take your time with it, you'll pick up speed with practise.

try cross on left
just put the first pair into the BD slot, and the other three will be before you.

 

[Moops]

Yes. I've been practicing R U R' U' + L U L' U' and all it's variants for all four slots. The cross on left is interesting, I"ll try it out. Thanks!

Do you mean using D in inserting the first pair?
(with COL?)

 

[blakedacuber]

Teller has 2 videos atleast showing some amazing inserts for rotationless f2l and soe epic fingertricks too

 

[Godmil]

Also Macky's site is excellent for crazy F2L stuff.

 

[Pusha]

DRAGON_RYU, I mean using D for all pairs as much as possible to insert it into BD/FD slots

 

[Moops]

Thanks for the link. He's set out all the BL and BR inserts using only R U and L turns o.0 Awesome!

Teller is a freak... I could watch that man solve cubes for hours.

F2L insertions

There are four ways of inserting a corner/edge pair (for a slot, no mirrors or reflections):

• A common way to insert a connected pair is R U' R'
• A common way to insert a separated pair is R U R'
• Another way to insert a connected pair is R' F R F' which flips the orientation of the edges in up/front and front/right positions. This is good to know when inserting the last corner/edge pair to avoid some of the longer OLL cases when all edges are flipped
• R U2 R' changes to orientation of the corners in up/left/front and up/right/front for a connected pair. Whatever color is facing you before the algorithm will face up after the algorithm. Whereas the R U' R' only orients the corner in the up/right/front position. As for the corner in the target slot front/down/right doing R U2 R' the sticker that is facing you will point up and when doing R U' R' the sticker that is pointing to the right will face up after the algorithm.

These four algorithms inserts the pair in the slot, but do you ever think which one to use in a speedsolve for an easier case for the next corner/edge pair? They all permute corners and edges differently. One also orient edges.

When my last pair is connected and it's not being inserted in a slot in the back, I try to decided between something like R U' R' and R' F R F' to influence my LL.

But when the pair is separated, the only thing I know to do is something like R U R'. Are there any LL edge-influencing ways to insert a separated pair?

Sure there are. It's called VH F2L

 

[Hershey]

Sure there are. It's called VH F2L

Which is a really stupid subset that is probably not worth using. (Btw, we like to call it VHLS)

Edit: correction, it is not worth learning. Only one I would use is sledgehammer to avoid dot OLLs, which just orients 2 edges.

 

[Jaycee]

Thank you! I'm just going to learn the four ones on there for "Edge Separated"

But the R' F R F' one (+ mirror) are nice to know

 

[CrazyBadCuber]

I have a full F2L video series done professionally HERE: http://www.youtube.com/user/crazybadcuber?feature=mhee#p/u/0/BOHCpTuiNDg

It's not fully expert, but pretty advanced. Ranging from beginners stuff to really advanced stuff.

I hate linking my own videos, but it's pretty relevant.
