my tips is DO NOT CANCEL move in an OLL algrithm which is actually a combination of 2 OLL algorithm. some of them can be cancelled and some of them cannot be cancelled.

if you do sexy move + sledgehammer in solve 1 u will get Y perm

if you cancel 2 OLL algorithm in solve 2 (which is actually a combination of sune + sexy move + sledgehammer), you will also get Y perm

 

[Hjerpower]

I just got a pb single for OH (18.50) and I want to reconstruct it. however, I can't remember what I exactly did in the solve. scramble is U' F2 B2 D L F' L2 D R' U F2 R2 F D2 R2 L2 F' R2 D2 R2 B2. I did yellow cross and it started by solving the yellow-green edge and the solve ended with inserting the green-orange f2l pair and getting a last layer skip. This is probably a lot to ask but any help would be appreciated!
Edit: the last few moves went like U' R U' R' (AUF)

 

[Owen Morrison]

Do you know what colors your first F2L pair was?

 

[Hjerpower]

not entirely sure of that but i have a strong feeling it was green-red or red-blue

 

[Owen Morrison]

hmmm I found a solution that gives a PLL skip but I can't find one that is LL skip.

 

[Hjerpower]

okay, maybe i had antisune as my OLL and just didnt notice because i usually finish F2l around 14-16

 

[Micah Morrison]

dang, I must have tried 100 different solutions and didn't get an LL skip or an antisune PLL skip. It's harder when I don;t know what your solving style is

 

[Hjerpower]

sorry about that, my f2l solutions are sub-par and I don't even know how I did my cross. my best guess is to build cross a few ways, and do blue-red, green-red, and blue-orange and the last pair should be built

 

[brododragon]

Kind of off topic, but I bet HARCS/JARCS could be optimized and tweaked for taking a few specifications/possibilities and reconstructing solves based on it.

[Brest]

What's with that U-perm?

A majority of the fastest solvers use the R3 variant, saves a regrip.

 

[mista]

Yes, I like this Uperm variant so much. It is easy to fingertrick this one and do not mess it up. Here you have another fancy algs with R3:

[TheCube4226]

7.30 3x3 single on my first day back to practicing in several months. I'm barely sub-11 when warmed up so this is pretty solid for me. Totally should've been sub-7 and a PB but I locked up at the beginning of my J perm. Was able to find better solution afterwards but I'm still somewhat content with this one. I'm sure there are ways to have done a Cross +3 instead of the Cross +2 like I did but I haven't tried finding any yet. anyway, here it is.
