the fastest way to solve this...

[pm6]

hey, I hope there are someone to help me.
I'm a beginner, I started few hours ago.
Is there an algoithm so solve this:

as fast as it possible
I mean to change the position of the green/red in the middle. thx.

 

[qqwref]

Try R U F?

 

[zippur]

you cant switch the middles, but you can take the edge piece out then put in the right way

 

[Athefre]

I mean to change the position of the green/red in the middle. thx.

Are you using a layer method and trying to flip an edge but keep it where it is?

R2U2FR2F'U2R'UR' (Lt-Unreal posted that here once)

 

[pm6]

hey guys. I mean on the cornder NOT THE MIDDLE (red one)
the green one under blue and red under white.

 

[pm6]

in this position is my cube:

change the posirion green/red

 

[nitrocan]

Try what qqwref said (R U F)

 

[Athefre]

in this position is my cube:

change the posirion green/red

That's what I posted does doesn't it? R2U2FR2F'U2R'UR'

But turn your cube upside down to do it, or do F2D2RF2R'D2F'DF'

If you don't know the notation:

[nitrocan]

Oh you're trying to flip a second-layer edge.


Then do R U' R' U y' R' U2 R U2 R' U R for the Front-Right edge while the first layer is on the bottom.

 

[pm6]

puh, its many to rotate.
this is the only method to do this?
I can do this, but I'm seeking for a better/faster method.

 

[nitrocan]

You don't need a "method" to flip an edge.

This is the optimal solution to it: R2 U2 F R2 F' U2 R' U R'

 

[pm6]

Okay thx, I will try.

 

[pm6]

hey, this works, BUT: If I do this, I destroy the TOP of my cube, on the top is WHITE.

an idea?

 

[Ellis]

wheres stefan?

pm6, that algorithm that nitrocan gave will work if you put the solved layer on the bottom first, with that edge at the front right position.

But think about it, you already know an algorithm to put an edge in that place, presumably the correct one. So if you do that same algorithm, a different incorrect edge will be in that position and you can proceed to reinsert the green-red edge the correct way, as there are two ways to put the edge in.

 

[pm6]

hmhmhmh hey, I dont understand what you mean, sry. It works. what do you mean with "as there are two ways to put the edge in" ? sry, my english is not well ^^

 

[cookingfat]

You don't need a "method" to flip an edge.

This is the optimal solution to it: R2 U2 F R2 F' U2 R' U R'

wow, that's much better than the one I was using (F2 U2 R' F2 R U2 F U' F)

thanks.

 

[Ellis]

what do you mean with "as there are two ways to put the edge in" ?

The method that you're learning now should have two different algorithms to put in the green-red piece. One algorithm for each way that the green-red piece can be turned in the bottom layer before you do the algorithm. If you did an algorithm and the the green-red piece is wrong, you didn't do the right algorithm. To fix it, just do the algorithm again. Now the green-red piece is in the bottom layer again and now you can have another chance to do the right algorithm. Check your method, there should be two algorithms there.

 

[zippur]

if you put the white on the bottom, do this

R U' R' d R' U2 R U2' R' U R

 

[mcciff2112]

you can learn f2l, thats about it. theres no real way to teach it if you dont want to take the time to learn the ridiculous amount of algorithms for it. i dont know the algorithms but ive gotten it pretty fast

 

[JohnnyA]

That's a nasty case for F2L. I use R U R' U2 R U2 R' U y' R' U' R
