F2L solutions

Chris Hardwick
Method: Fridrich
Full Solve Average: low 15's, high 14's
Non-standard things I use often: Opposite cross solving, Xcross solving, empty slot shortcuts/keyhole

Scrambles:
1.) U R2 B' D' B' L2 U2 R' D2 R2 U2 F' B2 U F R2 L2 B2 R F2 R B2 L2 U L'

Cross: y D L R' D' L
1st pair: U L' U' L U2 R U R'
2nd pair: d' U' R' U' R
3rd pair: y L' U' L y' L U' L'
4th pair: U2 l U r U' r' U' l'
Total moves: 32

2.) L D' B F2 L B' R' U F' D F B U' F D R' B' R2 L2 B2 F2 R F U' D2

Cross: E' R' F B' D2 R' D
1st pair: L' U L U' L' U' L
2nd pair: U R U R' U' R U R' U' R U R' (sexy move!!)
3rd pair: U R' U' R U2 R' U R
4th pair: U2 L U L'
Total moves: 38 moves (very fast 2-gen though for 2nd and 3rd pairs)

3.)R' L2 B' D2 B' L2 U' R D' F R' F2 L U D' B' U R U R' U' D' B D2 R2

X-cross: y' D2 L F L' U L D' R
2nd pair: U2 R' U' R U R' U' R U R' U' R (sexy move!!)
3rd pair: R U' R' U2 y L' U' L
4th pair: U R' U' R U R' U' R
Total moves: 35 moves (I love the sexy move for that back pair insert at 2nd pair).

I suppose if I had to classify the X-cross I would call it a "keyhole style 2x2x2 first then finish cross" type.

4.) L R' B' U F D2 U' R' D2 F2 B D' R2 B' U2 F R' B2 R B' R' B' D R' B'

I don't like the D layer cross here, so I will do the U layer cross (opposite cross).

Cross: x2 R D F R2 y R2
1st pair: R' U' R U L' U' L
2nd pair: U' R' F R F' R U' R'
3rd pair: U2 R' U' R U R' U' R U R' U' R (sexy move!!)
4th pair: U L2 U2 L' U' L U' L2
Total moves: 40 moves (higher move count, but very 2-gen with the sexy move for 3rd pair)

5.)D2 R F2 D' F2 U' L2 R2 F2 B2 U2 F' D' R' L' D2 F U2 F' B R U2 L2 B2 D'

Cross: y R' F R2 u L2 u' D' R2
1st pair: U' R U R' U R U' R'
2nd pair: L' U' L U' L' U L
3rd pair: U2 L U L' U' L U L'
4th pair: d2 l' L' U' L U l U2 L' U' L' U L2 (ZBF2L to flip that last U layer edge, this is an easy case to execute and one worth knowing even for adding to partial cross solvers)

Total move count: 43 moves. I count u' D' as one fluid motion, or one move. This move count is very high, but try the solve and you will see that it is easy to execute because it is very 2-gen.

----------------------------------

Analysis of my own solving. I seem to have a very high move count for my F2L, but it is because I am using 2-gen algs as much as possible. I tend to execute the longer 2-gen alg variations at 90-95% speed while trying some minimal look ahead. I often have a short delay after the execution of a double sexy move style F2L pair until I find the next pair. So I guess for pairs where I use a longer 2-gen alg that my solving is short and choppy vs. slow smooth the whole time.

----------------------------------

Hope this helps someone. Now I'm off to read others' F2Ls to try to learn new tricks!

Chris

this is really good your the first person (as you can see) to really annalyze your own f2l solutions in written form so that not only does it benefit you but also the others who read this.

keep em' coming

Method: ZZ.

I rarely time myself, so I don't know my average. I'm just working on lowering my move-count at this point.

I've just switched from Fridrich a few months ago, so my block building skills are still sub-par.

These solves were done slowly, and all but the second are linear. I tried that one several times to get an optimal EOline.

3rd pair: U' R U R2 U' R U

Total moves: 36 high move count. The solve didn't feel nice at all.

Generally my move count is much lower than I thought. I seem to use a lot of x rotations, but they don't feel out of place when solving f2l with cross on left. I do wonder if other cross on left users use many x rotations aswell?

Why do you even have people post their method? (all use fridrich)

 

[Cride5]

1.)U R2 B' D' B' L2 U2 R' D2 R2 U2 F' B2 U F R2 L2 B2 R F2 R B2 L2 U L'
F2 R' F U F'
L U2 R2 U L2
R U2 R' U' R'
L' U2 L U' L'
U2 R' U R' U2 R2 U R2 U R2 (god I hate that case)
30 moves

There's a more efficient alg for that last case: F2 L D' L D L2 F2
I was using it for a while, but switched back to your less optimal one for better finger friendliness

2.) L D' B F2 L B' R' U F' D F B U' F D R' B' R2 L2 B2 F2 R F U' D2

R' D' F U' L B' (this took me forever to see)
U R U2 L2
U R U' R' U L' U' L
R' U' R U2 R' U R
U2 R U2 R' U2 R U' R'
34 moves

Nice elegant EOLine. If you're going for FM then aiming for a group 1 line (ie. not having to place the line using a D or D' turn) is better in the majority of cases.

4.) L R' B' U F D2 U' R' D2 F2 B D' R2 B' U2 F R' B2 R B' R' B' D R' B'
D U F B' U' B' (yay optimal!)
U' R2 L2 U2 R' U' R'
U L U' R' U' R
L U' L' U2 L
U2 L2 U L2 U L
30 moves

Nice use of multislotting for the final LH side ... or should it be called multiblocking for ZZ?

5.)D2 R F2 D' F2 U' L2 R2 F2 B2 U2 F' D' R' L' D2 F U2 F' B R U2 L2 B2 D'
R2 F R L' D' B' R D' (terrible, but I didn't see anything better)
R U' R' U' L' U' L
R2 U L U L'
R' U R U2 R
U' R U R'
29 moves

There's a 6-move solution to that EOLine: U B2 R' U F B ... but I'll admit, I never saw it either

Why do you even have people post their method? (all use fridrich)

[Johannes91]

U2 R' U R' U2 R2 U R2 U R2 (god I hate that case)

There's a more efficient alg for that last case: F2 L D' L D L2 F2
I was using it for a while, but switched back to your less optimal one for better finger friendliness

Another one: (U) R U2 R U' R U R' U2 R'.

 

[jms_gears1]

Why do you even have people post their method? (all use fridrich)

if you have not read the entire thread then you should do so, not everyone here that has posted uses friedrich, ex: cride uses zz and so does that guy the one with the funny hat

and so to this post i say: :fp

 

[GuyWithFunnyHat]

U2 R' U R' U2 R2 U R2 U R2 (god I hate that case)

There's a more efficient alg for that last case: F2 L D' L D L2 F2
I was using it for a while, but switched back to your less optimal one for better finger friendliness

Another one: (U) R U2 R U' R U R' U2 R'.

Alg I just found: R U' F' r U R' U' r' F

EDIT: Ack, this was supposed to be part of a larger post, but I screwed something up. Just read the one on the next page.

 

[Anthony]

Alg I just found: R U' F' r U R' U' r' F

I've never seen that before. I like it.

Edit: I think it totally pwnzzzzz. xD

 

[GuyWithFunnyHat]

U2 R' U R' U2 R2 U R2 U R2 (god I hate that case)

There's a more efficient alg for that last case: F2 L D' L D L2 F2
I was using it for a while, but switched back to your less optimal one for better finger friendliness

Another one: (U) R U2 R U' R U R' U2 R'.

Alg I just found: R U' F' r U R' U' r' F
EDIT: I've found some more algs for the same case in different slots. RB : F' r U R' U' r' F U R and
LF: r U' R2 F' r U M2 F. I'm still working on one for LB slot. The M2 in the LF alg works best when performed as Erik Akkersdijk does, with the right hand third finger.

4.) L R' B' U F D2 U' R' D2 F2 B D' R2 B' U2 F R' B2 R B' R' B' D R' B'
D U F B' U' B' (yay optimal!)
U' R2 L2 U2 R' U' R'
U L U' R' U' R
L U' L' U2 L
U2 L2 U L2 U L
30 moves

Nice use of multislotting for the final LH side ... or should it be called multiblocking for ZZ?

Does it count as "multiblocking" if it's just a nice cancellation? The whole solution was "L U' L' U2 L2 L' U2 L2 U L2 U L." I probably wouldn't see it in a speedsolve.

 

[jms_gears1]

This Thread works better than i actually anticipated i like the discussions and commenting on others solves especially ones that are helpful

(yea this is a slight bump >.>)

 

[IamWEB]

Man this thread is exactly the type of thing I was looking for, THANK YOU jms gear1 for your great thread. ;P

(Will post my solutions when I'm less tired).

 

[jms_gears1]

i think that people who use diffrent methods should post here, if im not mistaken we have 2 zz users and 2-3 petrus user so thats cool but we have plentiful amounts of fridrich users.

If i may be so bold to ask if you use zz petrus roux heise etc. some of the less commonly used methods please post here so that others can benefit, as well as you.

maybe ill try my best at petrus for my solves tho theyll probablly suck. xD

I'm still fairly new to ZZ (I average about 29 seconds), but here are my ZZF2L solutions:

In the second solve, once you reached this stage did you notice the lucky block ready to slot into the back-left slot? From here a quick R' U2 R would have done your RH 1x2x2

 

[miniGOINGS]

Do you want me to post my solutions? I only average sub-30 so I'm not that incredible, I can insert DF and DB to make it an F2L solution for you if you would like.
