What is the most efficient way to solve this case to get a white face?

U R2 U' R2

The U is a setup, R2 makes a bar on the top, U' and R2 combine both bars.

 

[qwr]

if the bottom 3 pieces already make 3/4 of a full layer there is R U2 R' (U' R U R'). making a bar with R2 will swap the pieces the pieces making up the bar in the bottom

I know, but he asked for the most efficient way to make a FACE, not a layer.

wow, i needed that! thx!

 

[lucazdoescubingstuff]

whats the best way to solve this? what i do is do an R2 and t perm then R2'

This is great!

This will be useful for when I learn cll, and I'll probably use this if the 3 are already solved.

It's unclear what you're asking here but my guess is you meant to complete an orange layer, and used the R2 U' R2 which does a face instead. See qwr's message above for a layer solution.

Also, to convert this to a layer, you can use R2 U R' F R F' U' R' or any LEG-1 alg that you prefer.

Similarly you can also rotate so the pieces are in front and do an EG-1 alg.

its actually for pbl, sorry

Best 2x2 Algs

docs.google.com

Refer to the PBL tab

I just invented a bad diag swap PBL lol

R' U R' F2 R F' U R' F2 R F' R

I invented some algs for these cases (layer on top, bar on bottom)

Try them out and see how it goes

R2 R U R' U' R' F R2 U' R' U' R U R' F R2 is what you are suggesting. R2 + R is just R'. So the alg becomes R' U R' U' R' F R2 U' R' U' R U R' F R2

 

[qwr]

R2 R U R' U' R' F R2 U' R' U' R U R' F R2 is what you are suggesting. R2 + R is just R'. So the alg becomes R' U R' U' R' F R2 U' R' U' R U R' F R2

The problem with this is it's still too many moves and it doesn't handle bars in different positions. The algs I suggest are 10 moves at most.

Which algorithm is better for the P1 EG-1 case?

F2 R U R' U2' R U R' U' F (Bar in back)

R U' R2' F R2 U' R B2 R2' (Bar in front)

 

[SpeakCuba]

Which algorithm is better for the P1 EG-1 case?

F2 R U R' U2' R U R' U' F' (Bar in back)

R U' R2' F R2 U' R B2 R2' (Bar in front)

I don't know EG-1, but the first one seems to flow better.

 

[ruffleduck]

F2 R U R' U2' R U R' U' F (Bar in back)

R U' R2' F R2 U' R B2 R2' (Bar in front)

I would prefer the second as starting an alg with F2 is an oof. But when it comes to 2x2 it's best to know as many algs as possible for cancellation purposes and angles (use either depending on where the bar is).

F2 R U R' U2' R U R' U' F (Bar in back)

R U' R2' F R2 U' R B2 R2' (Bar in front)

I do know that most EG1s have bar in back so doing the first one will let you not do the double rotation.

Would it be possible to one look an ortega solve?

yes. for example if you have a really easy first layer with a sune for OLL, you could know PBL and AUF, since all sune corners do a U2
