M & M' for F2L

[Akuma]

The only F2L algorithm I use with M are during edge control (VHF2L) when I get dot cases.

During cases like this:

I use L F L' U2 M' U M

I would also sometime use M & M's sometimes when I messed up the cross and I already started to insert F2L pairs. Like say I need to switch two cross pieces opposite next to each other; in that case I do M2 U2 M2.

some F2L pair stuff that forces OLL skips:

M'U'r'FR

r'U'RUM'

U2RUR'U2y'r'U'RUM'

U2RU'R'U'y'r'U'RUM'

R U R' U2 y M' U' r' F R
R' F' r U M y' U2 R U' R'
U R U R' U2 M' U R U' r'

etc...

O thanks
I'll see how handy it comes in later

I don't use slice moves like M and M' in my F2L.
I thnik it makes F2L slower . I just control edges on last pair .
any way I found this shrot alg for inserting rotationless when you have pair in back layer : f R' f' or U f R' f'
do the inverse of one of those algs to see what i mean . but remember that these two alg may disturb your look ahead.

R U M' U R' U' M
M' U R U' M U R'

I had a load once but most seems to be forgotten now since I don't do F2L anymore =)

Edit:

Rw U' Rw' U2 Rw U M U R'

The inverse solves the mirror case.

R Rw' U L F' L' U' M' is the alg in the vid.

I don't use them, but sometimes I improvise. I rarely gain anything by doing so though.

thanks, It's going to reduce my cube rotations a lot.

Are you talking about that case specifically? You don't need to rotate for that regardless of whether you use M/M' or not.

Some nice tricks in here. I'll have to get around to learning some of these.
