My winning solve in Asian Championship 2012.

I firstly, maybe in 3 min or so, found a nice start:

2x2x3 block: U D2 L2 B2 R2 B2 D L

I found the same 223 block too but failed to end with a good solution.

The following is my solution:

Spoiler

2*3*3 block with 3 1*1*2 blocks: L' F D' R U2 D B' D2 L2 D L * R'
F2L: B' U B2 U2 B' U' B U
Last 3 corners: L' D' B' D B L B
Insert at *: L' B R B' L B R' B'

The final solution: L' F D' R U2 D B' D2 L2 D B R B' L B R' B' R' B' U B2 U2 B' U' B U L' D' B' D B L B (33 moves)

The insertion is one of the optimal insertions.

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

Interesting scramble!
By using NISS there is a 3 move roux block and after 6 moves 1st part of the 2nd block (sorry, notes page at home…)
But even with all these blocks I could not find a nice continuation…

Not good result for me, but it was the best I could do at the competition.

But you won the comp nevertheless 

Harvard Fall 2012

Lol scramble, blocks galore!
And it shows in the results too 
What happened with your solve?

My winning solve in Asian Championship 2012.

Scramble: B D R2 B2 R F2 D R2 L' F U2 R B2 U2 L' B2 L2 F2 L2
Solution: U D2 L2 B2 R2 B2 D L U' B2 D B2 D' B2 U D2 B2 D B' L B2 L' B2 U R D' R' U' R D2 R' (31 HTM)

Misleading scramble, but got a 28 move solution today during my daily bustrip

 

[porkynator]

For the first time I used an orient-first method for an FMC solve; result was 34 HTM, but I got F2L-1 + EO in 16.
Scramble: R2 F2 L2 U2 L2 U R2 F2 D L2 U' R U' F L2 F2 L2 D2 F2
L2 F2 D2 F' //EO(4/4)
R' L D2 L U //Line + 2x2x2 (5/9)
D R' D //2x2x3 (3/12)
R2 F2 R' F2 //F2L-1+EO (4/16)
And then I could'nt find a good solution during the rest of the hour (I always give myself one hour for an FMC attempt). This was my best:
D R D' //One pair (3/19)
R2 D R D' R D R' * D' R //All but 3 corners (9/28)
* = B D' F' D B' D' F D //Corner 3-cycle (8-2/34)
Any idea on how to continue after the F2L-1?

(Sorry for double posting)
I randomly decided to compete at fmc.mustcube.net and...

Spoiler

Scramble (fmc-mustcube.net round #422): F' L B' D' U2 L F D2 B L' F' B2 R B2 U2 L' R B L F2 D R' F' R B F U2 D' F' B'

I tried this scramble yesterday, but I couldn't find a good solution within the hour. So I decided to try to solve it again today, competing in the "no time limit" format. Anyway, I got this solution in about 50 minutes since I started today. I consider this my PB, although I technically used more than 1 hour.
I wanted to try to orient edges as first step again.

D F' U L B //Orient Edges (5/5)
L D' //2x2x1 (2/7)
L U2 L2 U2 //Another 2x2x1 and a nice CE pair (4/11)
* L2 U //Lots of blocks! (2/13)
L D' L D B2 D2 R D //All but 3 corners (8/21)
* = B' R B L2 B' R' B L2 //Corner 3-cycle, 2 moves cancel out (6/27)

Final Solution: D F' U L B L D' L U2 L2 U2 B' R B L2 B' R' B U L D' L D B2 D2 R D (27 HTM), my new PB!
I'm starting to thing that orienting edges first can be very good for FMC.

Like a bau5
Took nearly the entire hour.

U2 D L' B' U2 D2 L U2 // 2x2x3 [8]

Final solution: U2 D L' B' U2 D2 L U B2 U R2 F2 R2 F2 R2 F U' B2 U F D2 F D F2 D2 (25f)

Noob to FMC

I am new to FMC. I would like to learn how to get good at it. I presently know all of the big 4 methods. Which of those four should I use or should I freestyle? What tips do you have?

 

[mycube]

freestyle as a mixture of all methods is the best alternative. you need a lot of blockbuilding(e.g. roux). and practice.
also try to understand and use NISS and insertions. just take a look at some examples. it's the best way to understand what you can do at FMC.

 

[Cubenovice]

Read the FMC wiki, it has a good description and has links to the best threads, like this one.

 

[brandbest1]

I still don't get premoves. What is the point of them and how can you discover which premoves to use?

Help is appreciated.

solve blocks (rh is offset) and correct line: U2 R2 L' D2 L2 R (U' R'...

34 HTM

improved and corrected the solution I already posted. Can anyone tell me what 'NISS' actually means? A search reveals very little. I find FMC really interesting and wanna improve. Also, I am struggling to understand exactly what a premove is... any help/suggestions for improving skill in fmc would be greatly appreciated
