This is for CFOP F2L


(F U R U') R' F' (R U' R')

z U' R' U R2 U' R' U R U' R' U

R2 U2 R U R' U R2

z U2 (R2 U') (R' U R' U2)


Cute, and fun to execute. If you find that these mess with your look-ahead, don't throw the baby out with the bathwater--they are still viable for final pair dismount. I use them.

Those are so sexy, I understand your signature now ^^
I used to use the optimal alg, but I didn't like the lack of lookahead (afaik the 3rd alg is optimal)
Now I use (most of the time);
y' U' R' U R U R' U R U' R' U R
I use a few random tricks for this case here and there, but usually I use this.
I prefer the mirror;
(U) R U' R' U' R U' R' U R U' R'
I'm messing around with the multislotting options with your algs.

In a contest between the tortoise and the hare, multi-slotting will wiin the day with reduced move-count.

Why didn't you type it as (F U R U' R' F') (R U' R')?
It's just easy OLL and insert. I would just do the normal fingertrick though, you sorta take some time to reposition your hand with your fingertrick.

I like this, especially z U' R' U R2 U' R' U R U' R' U

Another one to possibly add to your list is this one. I got the idea for it from Andrew Kang:
R' U' R U' R' U R2 U' R' U R' U R

Yes it's a lot of turns, but if you execute the very last U turn by pulling with your right ring finger, then the TPS is very high. I'd say it at least averages out to approximately the same time as most "normal" algs. Plus it's very fun to execute since the TPS is so high :)

That's pretty nice but wouldn't it be better to just do R' U' R U' R' U R2 U' R2' U2 R?

edit: eh I just realised both the algs solves the mirror case not the one in the video

I just tried it--that's pretty slick! Thanks!
