Hedges from the back:
Back left: f U' f' L
Back right: f' U f R'

It's quite awkward to execute. Is it worth it?

Yes of course it's worth it. I can execute it in 0.5x seconds.

 

[Cubing Forever]

Agreed. Thanks for providing multiple solutions for the even cases!

@BenChristman1 @DNF_Cuber @Cubing Forever, how are you executing the f R' f' and mirror for back slots? I can't seem to find a finger trick solution that's comfortable. Are you starting with a regrip, homegrip, what's the scoop? Thanks!

Didn't get notif for mention.
A bit late but you can execute it in homegrip with thumb f/f' but don't keep your pinky under the S slice.

 

[fadsarmy]

Yes of course it's worth it. I can execute it in 0.5x seconds.

For f U' f' L, are you doing first f with left thumb or right index?

 

[Cubing Forever]

With the index bc thumb is too awkward

 

[fadsarmy]

With the index bc thumb is too awkward

You're right. That's much easier, thanks.

I found an alternate way to solve this case:

R' U' R U' R' U2 R2 U2 R - 9 moves

The standard algorithm for this is this: U R U' R' U' R U' R' U R U' R' - 12 moves

Which one should I use?



Also which is the best way to solve this one?

R U F R U R' U' F' R' - 9 moves

or

R U' R' r U' r' U2 r U r'


And for this case:

R F U R U' R' F' U' R' - 9 moves

or

r U' r' U2 r' U' r R U R' - 10 moves

Is there a typo in R' U' R U' R' U2 R2 U2 R?

Thanks for the reply. I have another question:

Which alg should I use for this?

This is a mirror of another one where you rotate y' and then do the alg but is there a better one? Would be cool if it was rotationless, but if not then I'll stick to the standard one.

I would recommend you just rotate and do the standard solution (y or y', depending on which slots are remaining). If it's the last slot though then I would recommend you pair it up with sledge (R U' R')

thanks for the reply again! Ima rotate y so I can insert back and I can see pieces from the front slot.

One last question: Also you said to do it with sledge and then insert with R U' R', but there is another way to inverse sexy into sledge, which is 11 moves, while the sledge with R U' R' insert is also 11 moves. Is it better or just stick with the one you just said?

 

[Llewelys]

Time both solutions and pick the one that's fastest for you
(When in doubt, time it out)

 

[MrOrungUtan]

I am quite experienced with F2L and my advice is just look ahead at your first F2L pair from inspection and keep on looking ahead!

y F U' R U R' U R U2 R' F' is also good and almost 2 gen or you could do y r' F2 r U r' F' r or if you like lefty moves then you could do y L' U2 L U L' U' L both of them are short and regripless

Yes of course it's worth it. I can execute it in 0.5x seconds.

I'm really struggling with the finger tricks with f U' f' L. You mentioned doing the first f with right index. What about the second f'?

Right thumb works fine. A riskier one is right index push.

 

[fadsarmy]

F R' F' R

Is the first F with right thumb or right index? I prefer right thumb but I see most people using right index.

I avg 45.46 on 3x3 but i know i can decrease that time by alot if my cross and f2l wasnt so baddd. I watched jperm's vid about cross but i still dont grasp the idea of it. And my f2l can be wayy better if i didnt have to cube rotate to insert every pair i make. Did anyone else have this problem and how did you get out of that situation. I also have a example solve i did 2 days ago, i can link that if you want to see so you can give me a better answer to my question. Thank you in advance

 

[duckyisepic]

My advice to stop timing your solves. It's quite addicting thinking timing your solves is the best way to get faster. Focus more on deliberate practice such as if you occur a f2l case, slow down, think what solution is not going to have a cube rotation. I'm a terrible explainer, but Felix and Khan may help you,

I also think you should solve the cross and f2l slow when practising. This reduces pauses and you may find better solutions for cases. For cross, try to solve it in 8 moves. Brody's videos are very helpful imo. here's one link:

At this stage, it's more so you getting used to f2l and getting the cases you see in your muscle memory. F2l was frustrating for me when I was averaging 40s. It just comes to practise and having the motivation to not give up. Hete's an f2l vid from Brody that may help
