[Help Thread] FMC Discussion

[okayama]

Hi,

I've just registered for this site, with Guus's suggestion in fmc.mustcube.net.

The scramble of Round 291 (Official/Classic) was very impressive for me. I found the following solution besides the posted one.

Scramble: L' F B2 D R D' F B' L2 U' R' U' L2 U F2 D U R' L' D' B2 F2 R2 L U F R U2 B2 R2

Solution: L' U' L U L' B' U2 B U' L2 F B2 R' F R B2 R' F' R2 F R' D' R F L' B' L' (27 htm)

(For inverse scramble)
1x2x2 block (a): (premade!!)
1x2x2 block (b): L B
1x2x2 block (c): L F' R' D R F'
F2L minus 1 slot: R' * F' L'
More 1x2x2 block: L' U B' U2 B L
All but 3 corners: U' L' U L

Insert at *: R' F R B2 R' F' R B2

The start L B L F' was used as the pre-scramble in the posted 22 moves solution.

Hi,

I've just registered for this site, with Guus's suggestion in fmc.mustcube.net.

Hi Tomoaki,

Welcome to this forum. I hoped you did response to my suggestion and you did!
You have become a expert FMC-solver and very hard to beat.
You know all the tricks, inclusing NISS. I advice almost every FMC-competitor to learn more LL-algs. My advice to you is: don't! It's very dangerous

That 22-mover for #291 was awesome. I too "smelled" a short solve but I got stuck on 25 moves.

I saw you best competition solve is 31 moves. I'm sure you can improve. When is your next competition?

Did you know there is a weekly competition on this forum? (see the Weekly Forum Competitions on the Forum) including a FMC part?

Well hope to hear from you more often.

Gus

Thanks for your comments, Guus.

I advice almost every FMC-competitor to learn more LL-algs. My advice to you is: don't! It's very dangerous

Hmm, did you mean that I should NOT learn so many LL-algs? Why do you think so? I'm very curious.

I thought it's nothing wrong with knowing LL-algs as many as possible. They are useful when one finds a short (pseudo) F2L, and in fact it seems that you successfully implemented the strategy many times in FMC. I currently know only a few OLL and PLL, so I envy LL-algs experts like you.

I saw you best competition solve is 31 moves. I'm sure you can improve. When is your next competition?

My latest average (10 of 12) in 1-hr solve FMC is 32.8 (excluding DNF), so it might be difficult to break the record at present.

Unfortunately FMC is a very very minor event in Japan (only 3 times so far). If the worst happens the next competition will be Japan Open 2011. But I've heard a bit about a big cube competition held in summer this year, so I hope there will be FMC in the competition.

Did you know there is a weekly competition on this forum? (see the Weekly Forum Competitions on the Forum) including a FMC part?

Wow, there are many events. Thanks for letting me know, I will participate in it before very long.

I Believe Guus was saying that you should not learn LL algs in jest. I could have read it wrong however.

I need to start looking into FMC, its one of the few things i would like to be good at.

And welcome to the forums.

OK ha-ha, why don't we become dangerous together?

I got a really easy scramble during speedsolving and decided to try for FMC too:

D' R' D' L' B' F' D' B F2 R' B' F U L' R F2 U R2 D' R' D' U B F L

Spoiler

F2L: x2 U2 L’ F2 L U2 L’ F’ L’ F U R’ F’ U F R (15)
LL: F U R U’ R’ F’ R’ U2 R U R’ U R (13)
Total: 28

Another solution with a similar start, but illegal, because I looked up the ELL algorithm:

F2L: D2 L’ B2 L’ D2 L’ B L’ B’ D R’ D R’ (13)
ELL: x2 U’ F U R’ U’ R2 F’ R’ U R U’ R2 (12)
Total: 25

I think you guys can do a low 20ish on that one.

After taking a long time to remember the alg Guus taught me at worlds I found this:

Scramble: D' R' D' L' B' F' D' B F2 R' B' F U L' R F2 U R2 D' R' D' U B F L

D2 L' B2 L D2 L' B' L' B D R' D R' S D S' D S D' S' D' R2 (26 HTM)

Well done, I'm proud of you!
And that's exactly what I found in 5 minutes or so.
But I think getting sub-25 is very hard on this scramble.
Anyone?

That's insane! I never really tried premoves/inverse scramble... It seemed too easy to get advantage out of that xD

I participated in the weekly competition for the first time. (2010-20)

Scramble: L R' B' L2 D R' U' R F2 R U' F' U2 L2 B' U F2 R2

The given scramble looks so nice, since there are a lot of c/e pairs. However I could not get sub 30 in 1 hour... and even after that I can't go more than 28 moves.

If anyone finds a better solution or improvement of my solutions, please give a reply here.

Here are my solutions:

Scramble: L R' B' L2 D R' U' R F2 R U' F' U2 L2 B' U F2 R2
Solution 1: F2 B' R' U' R U2 B L2 F2 R2 B R' B2 L' B R B' L B D2 R' F R D' F2 D' L' D (28 htm)

Spoiler

(For inverse scramble)
Pre-scramble: F2

1x2x2 block (a): D'
1x2x2 block (b): L D F2 D R'
1x2x2 block (c): F'
Move c/e pairs: R D2 * R' B R B'
F2L minus 1 slot: R2 F2 L2
All but 3 corners: B' U2 R' U R B
Correction: F2

Insert at *: B' L' B R' B' L B R

Scramble: L R' B' L2 D R' U' R F2 R U' F' U2 L2 B' U F2 R2
Solution 2: F R' B' D B U' B' D' B R U F R B U2 F' U F U' R' U2 B U2 B L F' D R2 U R' (30 htm)

Spoiler

The same start (first 10 moves) as my 1-hr solution.

(For inverse scramble)
Pre-scramble: F2

1x2x2 block (a): R U' R2
1x2x2 block (b): D'
Pseudo 2x2x3 block: F L' B2
Orient edges: B U2 B'
1x2x2 to 1x2x3: U2 R
More 1x2x2 block: U F' U' F
Finish F2L: U2 B'
All but 3 corners: R' F' U' R' * U R F
Correction: F2

Insert at *: B' D B U B' D' B' U'


In this solution, 18 moves are needed for solving F2L (including premove), but I found 17 moves F2L as follows:

Scramble: L R' B' L2 D R' U' R F2 R U' F' U2 L2 B' U F2 R2

(For inverse scramble)
Pre-scramble: U R2 U R U2 F2 B'

1x2x2 block (a): R U' R2
1x2x2 block (b): D'
1x2x2 block (c): F
Finish F2L: L' B' U B' U

However I could not find a good continuation and gave up using the frame.

Hi Tomoaki

Welcome to the weekly competitions. We can now compete on two forums each week!
Despite all those pairs this week wasn't an easy scramble after all.
I got 28 moves too, but just within the hour.
I used NISS this time, actually I'm not a frequent user of my own invention....

R' B R F2 R B U' B' U' R2 U F' U F U2 B' R' B R U R2 B2 L F' D R2 U R' (28)

start on inverse scramble: with premoves [B' F2] R U' R2 D' F L' B2
switch to regular scramble with premoves [B2 L F' D R2 U R']
F2L: R' B R F2 R B U' B' U' R2 U F' U F U' (15)
LL: U' B' R' B R U R2 (21)
pre-move correction: B2 L F' D R2 U R' (28)

Well FMC are really hard to win. The average winner takes it's time about 8 seconds, need a lot of practice not algorithms..

Hi Guus,

Hmm, you also thought it not so easy after all. But Sub 30 in 1 hour is still wonderful!

That is exactly the same start (2x2x3 block building) I found in 1 hour! But I never tried to switch the normal scramble at this point because I couldn't see any c/e pair there. In reality, however, there is a c/e pair at a nice place in the normal scramble! I misunderstood the situation... Very informative, thank you.
