The FMC thread

[guysensei1]

shouldn't i just do the alg+AUF before the scramble rather than the inverse?

And i think it was F sexy F' U2 but I don't remember the orientation

Yeah you're right.

 

[BQ]

Why can't insertion finder find optimal for this?

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

Spoilers for the facebook weekly comp btw

Spoiler

*L* R' D' L2 *D* B U2//2x2x2 with 2 inserted moves (7/7)
B2 L D2 L B' D//F2L-1 (6/13)

Final: L R' D' L2 D B U2 B2 L2 D' L' U2 D2 R D R' U2 L B' D L2 F L' F' L D' L' D (28)

IF says 29 for some reason.

There's a bug on the IF.

(FB weekly comp spoiler)

scramble: R' U' F R2 F2 R2 U2 R2 D F2 U B' D U F' L' F2 D B D2 U' L2 B2 R' U' F

R' B' R D F2 // 2x2x2
U' L' U B' L' B' // 2x2x3

I found a continuation to F sexy F' pll skip but I lost it. If anyone can find it I will be super happy.

Any chance in the world it is R F2 L2 F2 R' D' F2 D2 L2 F L2 D2 B' L' B L F2?

Cancelled moves in an insertion for the first time i believe(2 yay)
also optimal insertion so thats kinda cool

A few questions. I'm going to a comp with FMC and wanna get sub 35ish before I go. I know basic blockbuilding, NISS, Pheudo blocks, and some EO. No insertions, edge cylces or anything super advanced.

What algs/things are most important to get sub 35 before the comp in just under 2 months?

Should I always have a backup solution (I do really want a mean), and what is a good place to learn time management?

Thanks,

Duncan Bannon

Insertions are the most important. Learn how to do 3/4 corners (and also 5 corners, or twist, but it is basically the same thing). You will need corner commutators for this (just the "pure" cases). You can also try edge insertions or other things, but go for corners first.

It's a good thing to have a backup solution written at some point, maybe after 30 minutes or so, but you don't need to in case you some half-solutions and you are confident you can finish them in time.

For time management, I can't give any advice, except: pratice. Do 1hr attempts and try to see what's going wrong when you run out of time.

Thanks for the advice @porkynator, I really like your FMC guide!

I apologize if my questions are clogging up the thread.

How would you approach a scramble like R' U' F L' U2 F2 L2 F2 R' B2 R' B2 D2 L' F' L2 U' L' R F' D R2 B R' U' F were there are no 1 move 1x1x2 blocks?

You are welcome, I'm glad you like it!

If there is no good blockbuilding start, it may be a good idea to start with EO. In this case there is no very good EO case (on all orientation it's 6 or 8 bad edges), but you can do something like this, on the inverse scramble:

EO: (D R2 F' B D)

which doesn't look very good, you can modify it to:

D
F (save pair)
R2 F2 B D //EO

and continue with
L' B2 //2x2x2 + pair

So I just came up with this solution for the Weekly Competition 2018-16 and I am pretty happy with it over all, but if anyone has any tips that they see that I should keep in mind for future solves (especially for the 2x2x2 and 2x2x3 blocks), then I am more then open to ideas. Thanks.

help would be greatly appreciated, i really wanna avg low 30 before Indian Nationals and I know NISS, pseudoblocks, insertions
Also would you insert 3C+2TC or just leave it? i got that once(before, not on this one)
