I've got your point. The audience here is looking for fastest methods.
OK
But is there any forum to discuss the theory?

Very nice tutorial Dmirty!


A little suggestion to make the final edges easier.

It is fairly straight forward to complete 3-edges in the U-layer just by placing edges intuitively. After completing the three edges there are three possible scenarios:
(1) The fourth is solved and you are done
(2) The fourth is in place, but flipped
(3) The fourth is in the 'slot'

Dealing with (2) is easy to do intuitively. Simply remove one of the solved edges, so that the flipped one goes in the slot. Intuitive completion should be easy from here. For example in this case:

... do:
R U' R' - remove an edge
U F' U F U' - now solve intuitively

Dealing with (3) can be done with your four move algorithm. Simply place the unsolved edge in UB, do the four moves, align two solved edges, and now place the third (automatically solving the fourth). So in this case:

... do:
U2 - place unsolved piece in UB
R U' R' U - your 'trick' alg
U - align two pieces
U R U' R' - then solve the third as normal
click for animation

If the unsolved edge is in the slot, but the other way round you can still solve the final edges the same way. Simply rotate the cube so that the R face becomes the U face (a z' y' rotation).


NOTE: this also applies to 8355 using the sexy move, only you place the unsolved edge in UF before applying R U R' U', and you need to be able to use the mirror F' U' F U

Cride5,

Thank you for the credit.

Actually there are 4 possible cases.

(1) The fourth is solved and you are done
(2) The fourth is in place, but flipped
(3) The fourth is in the 'slot'
(4) The fourth is not in place only, not flipped

Look
If I'm not mistaken the (2) is the same algo like I showed, but i use the same U'RUR' and RU'R'U but I rotate the cube in the middle of the algo.

Your (3) is the nice one and I think it's really similar. But U2 is in front.

When if I need at the same time to turn edge peaces and change spots (slot), I do the same algo of 8 moves that I showed, but I do one move setup before and one move after to undo the setup.
For the case you showed I would do R U'F'U'FU'F'U2F R'.

Here first R and last R' is a setup and setup undo.
The rest is the same 8 moves algo same like I use for the case (4) R'U'R'UR'U'R2U.

I just did not show that in the video not to make it overcomplicated. But I mentioned that.
The user can always use two algos and perform them one after another for cases (2) and (4). and that will give you the solution for case (3).

The pupose of the method was no memorization and no notation to show.
So I left only 3 algos.
RU'R'U
U'RUR'
and
R'U'R'UR'U'R2U
In each of them you use only two sides to move. R and U. You basically work with right hand only.
So the beginner has no trouble to make it without any memorisation at all.
