In actual solves, how do you deal with these difficult F2L cases?

[rubiknewbie]

Do you just bring up the corner pieces, use intuitive (I don't know how!), or use algorithms for any of these cases, or their mirror cases?

Use the number to identify any case to discuss. I took from cubeloop with some modifications.

EDIT: Yes I realise the mistake in 1-3. I have updated the correct attachment in post #3! Also you need to rotate y' at the end of the setup.

For case 11, y2 L' U L2 U2 L2 U L

EDIT: 1-3 and 4-6 are the same btw.

All the rest are bad cases for me pretty much.

 

[rubiknewbie]

This is the correct picture of the cases (1-3 different from 4-6)!

[Weston]

Honestly, most of he time I dont even have l worry about cases like this because theres usually a better pair somewhere else.

 

[frogmanson]

1.) R2 U R2 U’ R2
2.) Y z U L F’ L’ U’
3.) R U R’ U’ R’U’RUR’U’R
4.) Y R U’ R’2 u’ R’ u R
5.) L’ U’ L U’ R U R’ U’ R U R’
6.) I can’t do this one one-handed so I don’t wanna type xD (I’m typing the algs while executing the 2-handed algs one-handed)
7.) RUR’D’RU’R’D
I’ll stop here, too lazy to type anymore xD

 

[jiggy]

Blue cross? Eww!

I agree with Weston. And if I can't quickly see a better case, I would typically just kick out an edge/corner depending on which I think will put me in a better position. (I know, no great pearl of wisdom there, sorry.)

Another alternative is to spot these early on (if you can) and then open up one of those slots as you are building/inserting a different F2L pair. This can sometimes drag out one of the offending pieces for free.

I have some better adjacent-slot Jeff2L.

I'd just do the other pair first xD

 

[rubiknewbie]

Although it's not often, I sometimes get 2 adjacent corners with these pairs!

Also I hate having to switch pairs after I have wasted some time finding one, and then sometimes I can't find the next pair lol.

 

[sequencius]

It's better if you just learn them on your own. Just go slow and observe how they're working. Also try all the different possible way to solve each case, even with different rotations / inserting pairs from different angles

 

[blah]

From the given angle:
1. F Rw U2 Rw' F'
2. L Uw L' Uw' L'
3. R U - L' U2 L - R'
4. R U' R2 Uw' R' Uw R
5. R - U' L' U' L U' - R' or L' U R U2 L U' R'
6.
7. R - L' U L U' - R'
8. L F' L' (F F') U' R' F' R F
9. R - U L' U' L - R'
10. L Uw L' Uw' L' - R U' R' or R' F R U' F' R U' R' (fingertricky)
11.
12.

There are algs for other angles.

[Akuma]

I actually like cases like these because if one of the corners are in the bottom slot it makes look-ahead much much easier.

I can just go ahead and solve another pair knowing that the final corner piece is in the bottom-right slot facilitating the transition from the 3rd pair to the final pair.

I would like to take a look. But it looks jumbled up on my screen .

 

[CubesOfTheWorld]

If there are no other white pieces on the top(or in this case blue), I just live with it.

You should get a better browser.

I use Google Chrome. FireFox is good too.

[Edward]

Well, since all of those have another free slot, I'd just solve the not-bad pair first, and it usually makes the bad pair an easy one.

 

[rubiknewbie]

You got a point, unless both corners got these bad cases but that's rare.

However, looking at some of the algorithms, they are actually among the fastest algorithms (5 moves) in F2L if only I have the presence of mind to recognise the situation and use them .
