F2L with 0 rotation

[masterofthebass]

I actually do something else... as it only adds 3moves and no rotations.
Scramble: R U' R' d R' U2 R d'

R' U2 R2 U R2' U R

This way there's still no rotation, and it's still really fast.

What would you do for this scramble;
Scramble: R U' R' d R' U2 R

When I first tried this I didn't see the extra d' on the end. that changes everything.
R2 U2 R' U' R U' R' U' R, there may be a shorter way I'm going to go check.
Edit: R' U2 R2 U R2 U R

I realized that for some reason, I tend to rotate more on Ryanheise sim. I also could find ways to not rotate at all if I'm instructing someone else a bit slower rather than to solve myself. I don't think 1-3 rotations in F2L could hurt. If you rotate like crazy, then you need to improve your method.

hey, I've been cubing for 2 years now. iv'e go a 33 sec Average with 15sec inspection time.

i have been under 30. i solve the cube with rotations ONLY when i cant immediately see the F2L pair using any combination of RUR. but, for some reason i found that i ONLY ever rotate to the left. i believe that solving the cube with no rotations has to be faster theres no question about it.

 

[badmephisto]

I try to always solve using exactly 1 rotations. First construct 2 adjacent pairs and then rotate once and construct the other two. It doesnt always work but more than 2 or 3 rotations cant be good

A standars solve have 1 to 3 regrips (or rotation, or d moves).

You can reduce this score using F and r moves, but it's strongly recommanded for some cases.

In addition, rotation allow you to know what is in the LB slot (that you can't see easily otherwise).

But, begining with a 222bloc (as in petrus method) then extend it to a extended cross have some advantages.
1/ It's easier than doing EO during the cross (I try, it's realy difficult).
2/ The LB slot is solved when you start 2L, so you neddn't rotate the cube anymore to see different solts.
3/ You can end the F2L in RU style in majority of cases : RU for the two slots on the right, then switch cross left and continue RU.
4/ multislotting is easier because the numer of cases is greatly reduced.
5a/ You can use winter variation (28 cases) to get a OLL skip in 100% of the cases.
5b/ If you prefere, you can use COLL => ELL
5c/ Or ZBLL

EO isn't only a F2L boost, it's a preparation of LL and can speed up this step too.

I don't use this method in competition yet but work hard on it and believe it's a good solution.

I tend to rotate pretty much between every pair (unless I'm doing FR, then BR, but that doesn't happen much). It sucks, I think it really cripples me during F2L. So really, if I had the ability to do F2L with zero rotation (while avoiding B turns), I would.

 

[malcolm]

Instead of B U' B you can just use f R' f, for less rotations.

Since people are reusing this thread:

Yu Nakajima did a y-rotation during every step in his second 8.72 (except cross).
(Dunno about the first. Someone should post a video!)

Anyhow, if you don't like rotations, try pre-orient.

 

[brunson]

Lucas, can you elaborate on "pre-orient"?

 

[Lotsofsloths]

Pre orient= you orient the edges in such a way, that they(all 4 F2l's) can be solved ONLY using R U L moves.

 

[brunson]

So, you're pre-orienting during the cross or do you pre-orient your first pair during the cross, then each successive pair while solving the current pair? Not that I'm physically capable of doing either at this point but it's nice to understand.

 

[mizzle]

Preorient thread? You rang?

And the answer is that you mix a little of both. If you work at it, you begin to be able to do the cross as you orient, and it's only a couple of extra turns (under 10 total). Some cases, though, are just really hard to set up, or there's an amazing nonoriented cross.

For those, you use some VH style intuition to orient an edge or two during each pair, so that you're already done by the time you finish your third pair, leaving your fourth free to do Heise, corner control, or what have you.
