[Calode]

Thanks, I didn't see that psuedo 2x2x3. Definitely something I should be looking out for. I thought I had done the inverse scramble after the 2x2 and found nothing, guess I should look harder.

 

[Cale S]

Scramble: F D' R2 U2 B' R D2 L B D' L2 D2 B2 D B2 R2 L2 U' L2

and here's a very interesting 23:

U' R' // 2x2x2
(D2 L2 F) // pseudo 2x2x3 + pairs
(D F') // more blocks
L' B D2 B' D' // 3e4c

U' ^ R' L' B D2 B' D' F D' F' L2 @ D2
^ = F L D' L' D L' F' L // block comm
@ = [L2, F' R F] // corner comm

Final solution: U' F L D' L' D L' F' R' B D2 B' D' F D' F2 R F L2 F' R' F D2
23 moves

Trying to get into FMC. My first 3 solves were 42, 28 , and 33. This is my 4th attempt and decided to do it on a 2 move 2x2x2 scramble someone gave me. Btw, I know niss and insertions, just didn't find place for them here.

Scramble: F D' R2 U2 B' R D2 L B D' L2 D2 B2 D B2 R2 L2 U' L2

U' R' // 2x2x2
L D' L' D L F D2 F' // 2x2x3
D B' L' B L' // F2L-1
D' B D B' D B D B' D' L B' L' B // F2L
R' D' B' D B R // OLL + PLL skip

Final solution U' R' L D' L' D L F D2 F' D B' L' B L' D' B D B' D B D B' D' L B' L' B R' D' B' D B R
**35 moves**

How could I have done better? I feel like I wasted a 2 move 2x2 and a 10 move 2x2x3.

There's a lot of good blocks if you switch after the 2x2 and do D2 L2. I couldn't seem to find a terribly good finish on it though, this was the best I could find:

N: U' R' //2x2x2
I: D2 L2 D2 F L2 D L F' //F2L-1
D R' D R D' F D F' D' //L4C (19)

Insertions are lucky on this one, at least: http://mf.qiyuuu.com/cube/if/886d02fcda9039738f92049136c61e8a.cube

Can you explain what the inverse portion of your F2L step is doing?

 

[Cale S]

Can you explain what the inverse portion of your F2L step is doing?

I had to do a lot of manipulating things and cancelling moves, here was my thought process:

R2 F' L' D L' B' D' B2 L' D F B' L2 B L2 B' U2 F U2 R2 B

F2 U2 F // 2x2x2
(U L2) // 2x2x3
B2 // form 2 pairs
(B' U R') // pseudo F2L - 1
U2 R' // F2L - 1
(R U B') // make square (noticed because it cancels a few moves)
R B2 L // pseudo F2L with lots of blocks, this also cancels moves
(U' L) // fix F2L
R' F R U R' U' F' U R // LL

At Euros 2016, on the second scramble, I got a 28, however, I think I wrote it down wrong on the proper FMC sheet :,(

Finally decided to learn FMC in hopes of becoming more efficient in Speedsolving.
What's a good block building tutorial? I am struggling a lot with it.

I spent about 35 minutes trying to find a good start, until I tried switching after 1x1x2s, then found the 2x2x3 while trying to do a square. Then the LL skip made everything cool.

FMC is fun

There was a 3 mover on inverse with not many good continuations that I found, and I spent the majority of the time looking for good things after the 2x2x2s. Again, a lucky finish, but since not too many people know the alg, I don't feel really, really lucky. In the end I didn't even need the inverse haha

How did u get so good so fast

 

[Hssandwich]

How did u get so good so fast

Haha, I averaged about 38 before euros, then something just clicked. I also learned how to switch, so that really helped with everything, giving you multiple options. There were a little lucky too, especially witht the LL skip on the 27 and easy 1LLL on the 25. My next attempt was a 35, but that had a bad ending.
I try to always go 2x2x2 -> 2x2x3 -> F2L-1 -> Whatevee I can find to finish quickly, this might be a tripod block to then solve some of the edges or reduce it to 5c.

 

[wir3sandfir3s]

Haha, I averaged about 38 before euros,

But I average 50-60 now following sebastiano's tutorial...

 

[Hssandwich]

But I average 50-60 now following sebastiano's tutorial...

What part do you struggle on? Is it the block building? If so, try to get a 2x2x2 in 7 moves. This isn't too hard if you either have a pre-built 1x1x2. If you don't, you can usually get one in just 1 move, by just trying every move to see what it does. Then try to make a 1x2x2 by connecting the 1x1x2 to the edge and centre, then look for the other edge and put them together. Sorry if that didn't make too much sense
After that it's kind of the same concept to make a 2x2x3, make or use another 1x1x2 and connect it to its edge and then put it with the rest. Then the same for F2L-1. Then try to do EO and reduce it to 3 corners or 5 corners, which are usually the best to have for insertions.
I hope this helped!

Block building is only half my worries, I also cant get to L3C with two pairs for my life without going to an insane amount of moves... I can do it easy, I used to use Heise, just not for FMC.
