F' r U r'.

You can understand it as doing F' and then doing R U R' but the Rs are wide turns. (you know what a wide turn is)

omg this is amazing.. ty!

 

[IsI cubing]

I have a question, if I am used to solving the cube holding the cross on left, is it worthwhile to get used to solving F2L with the cross on bottom?

you will actually get used to solving f2l with the cross on the bottom

I am trying to upload a picture ... but it keeps saying the file size is too large... 1.28 MB is NOTHING.
Steve, 1.28 MB is a massive image, typical for a 5 megapixel camera jpeg, which would be roughly be 3 times larger than my computer screen. You only need something one-tenth that file-size for a screen-filling image, so the forum limit is quite generous.
If you resize your image to a sensible 800 pixels width, or thereabouts, the resulting file-size should automatically end up well within the specs.

I had to crop, screenshot, and crop again to finally be able to upload this. Is there another way I can reduce image sizes so I can upload them here?

Is there a video that shows pretty much how to edge control during F2L with many example situations and stuff?

"Is there another way I can reduce image sizes so I can upload them here?"
The answer will depend on what equipment you're using: camera and PC? Smartphone?
On a PC, even clunky old Microsoft Paint can crop and resize images. But I recommend downloading a freeware program called "Irfanview" , which is a proper photo-editing package that will do a huge range of things, including useful techniques like merging multiple images into one.
I'm not sure what the best options for smartphone are.

I can solve the cube in the regular way in about 50 seconds average and I am learning f2l. I can do it intuitively and my average is 70 seconds. My main issue with it is that finding the pieces. I can't understand how to do lookahead without learning all the algorithms.

Any help?

You don’t need to lookahead yet at your current average. I would suggest just to continue practising. When looking fir pieces don’t frantically search, quickly scan methodically and move the cube around if needed (don’t rotate tho).
I think what would be best is if you start learning the alg set. There are 42 of them, but a lot are mirrors and extensions of each other, and are fairly simple so it’s not too bad.

Try working out each case for yourself first though.https://www.cubeskills.com/uploads/pdf/tutorials/f2l.pdf

I had the same problem along with a few people I have critiqued.
Basically:
Slow solves -- When you do this, notice how many unnecesary U or D moves you do, and try to not do it when not needed.
Practice -- With time, you will get used to it

lookahead is not important right now.

I have the same problem when I use SS on my phone

Can someone please share some good algs for a flipped pair in the BL to BR slot? I'm using L U' L' U2 R' U R but was looking for something faster.

How about (L R')U2(R L')?

omg you genius...

omg you genius...

actually, my alg is worse for lookahead lol
you can mirror it for FL to FR like this:
F2 R' F2 R

How to solve this F2L case rotationless keeping blue in front?

The best solution I could come up with is: L' U' L U' L' U L U' L U2 L'.

If you feel your alg for this case is better, please share.

If you're a beginner reading this, wondering how to solve this case facing orange front, here's the (best?) alg: (U' R U R') U2 (L' U' L)

I've seen this floating around:
(U') L U L2 U' L2 U L'

I use:
(U2) L U' L U' L2 U L2
but I don't really think it's better (just more intuitive).

These are the shortest ones I could come up with:

U2 F U F' f' L f (use if it is 3rd pair)

This is a variation of y' U2 R U R' L' U L (use if you are lazy to learn how to do F and f moves)

another variation of this is y' U2 R U R' r' F r (use if you hate L moves)

 

[The_dark_cuber]

Thanks xyzzy and cubing forever. All the algs were way better than what I had been using but I think for now I will stick to (U') L U L2 U' L2 U L' & U2 F U F' f' L f, and figure out which is better.

 

[fadsarmy]

How would you solve this case for the back left? I normally do two back sledgehammers or rotate. Is there anything better?

Brilliant, thanks.
