Hi everybody - I've had a few requests for a reconstructions blog for the 5 solves in my 10.21 OH average from the Malaysia Cube Open 2017. There are a few changes that I and most people make for their one-handed solutions (as compared to 2-handed solutions) which can speed up your solves, so you might get a couple of nice ideas from this blog.

I also wanted to get this up before Max inevitably takes it sub 10 :p

Thanks a ton to Brest for doing some reconstructions much more efficiently than I could have done.

**Scramble 1: ****R D2 B2 L U2 B2 U2 L2 R' F2 D F2 R2 D' F' L B F U B2**

The first thing that I was drawn to on this scramble was the orange-green block in the top left position, so I wanted to try and make an extended cross. The way I built the extended cross wasn't great - the best way to do it was probably: y2 z U r U' R U R x' D2.

Inspection: z x2

Pseudo-cross: r U R U x' U R2

Finish X-Cross: y R U R' D2

The next pair was pretty straightforward - I probably should have inserted it into the back slot, but instead I rotated to do it 2gen.

2^{nd} pair: y U2' R U R' U2' R U' R'

There were a few different options for inserting the 3rd pair, I made sure to orient a last layer edge whilst inserting it.

3^{rd} pair: y U' R U' R' U' y z U' R' U z'

Time to orient some edges!

EO: y z U' R U y' z'

4^{th }pair: U' R U' R' U R U R'

Got a nice ZBLL after F2L - this one's fairly easy to recognise and even easier to execute OH.

PLL: U2' R U R' U' R U' R' L U' R U R' z U'

**10.28 seconds, 51 moves (STM), 4.96 TPS**

**Scramble 2: ****B2 L2 B D2 F2 L2 D2 F2 R2 U' R2 F' U L2 U L R' U2 F'**

This scramble doesn't look particularly nice on first glance, but the green cross is fairly decent and can be executed pretty easily as well. I don't even think that I saw the first pair in inspection here, but was fortunate that I was able to insert the first two pairs with just R & U moves, and without any rotations.

Inspection: z y2

Cross: U' (D z') y U2' R2 z R

1^{st} pair: U' R' U' R

2^{nd} pair: R U2' R' U' R U R'

After this, we can see that there are two blue (LL) edges oriented on the top layer, and so if I'm able to place another one in the top layer whilst solving the third pair, then keeping them oriented during the last pair will be trivial.

So, the way I solved the third pair brings a misoriented edge into the front-left slot, whilst also places the blue-red edge into the top layer.

3^{rd }pair: y' z U' R U z' U' R U R'

Indeed, after this, there's no more work to be done to orient the LL edges - the last pair is pretty easy.

4^{th} pair: y' U2' R U R' U' R U R'

Again, another T ZBLL for the last layer - the algorithm I use here isn't that great for one-handed solving, but it's still probably faster than OLL-PLL.

ZBLL: U' R' U' R U R' U' R2 z' R U' z U R z' R' U' z U2' R' U R U'

**10.04 seconds, 50 moves (STM), 4.98 TPS**

**Scramble 3: ****R' B2 L B2 F2 L2 B' F U L F D2 B2 F U B F'**

Yeah this scramble wasn't great at the start either - the blue cross was the only one with an edge in the cross layer, so I ended up going with that one. 10 moves is pretty bad, but I did a U2 before inserting the last cross edge because the fingertricks were safer and because it would move the orange-white pair into the top layer. U R U' R' U2' F D after the first 5 moves would have formed an X-Cross.

Inspection: x y2

Cross: U' R F z' U' R z U2' r U' r' D

As I was doing the first pair (orange-white), I noticed that I'd easily be able to insert the orange-yellow pair into the back before finishing it off, and thus I had a pretty nice multislotting case

1^{st} pair: U2' R U' R' U R U' R2' U' R

2^{nd} pair: R U' R'

The third pair was pretty easy to see and execute.

3^{rd} pair: y' U2' R U' R' U' R U R'

All my edges were oriented in the solve at this point, and after setting up the last pair, the Winter Variation case is pretty easy to do with one hand.

4^{th} pair setup: y' R U R' U

WV: R U' R' U2' R U' R' U2' R U R'

A little bit of luck here in that the V permutation was perfectly set up to the execution angle and there wasn't any AUF afterwards.

PLL: R' U2' R U2' z U R' D' R U' R U R' D R U'

**10.31 seconds, 62 moves (STM), 6.01 TPS**

** **

**Scramble 4: ****F2 U R' U L2 U2 B' U2 B' U' F2 U2 R' F2 R' L2 D2 F2 U2**

I was pretty excited after the first 3 solves, and was even more so once I saw the difficulty of this 4th scramble. There were a bunch of easy crosses, but I saw a green pseudo (offset) cross solution with an F2L edge and corner also solved in adjacent slots to one another. The other two pieces of these F2L pairs were also in the top layer, so I was able to use keyhole to solve them before re-aligning the cross pieces, to form an XX-cross.

Inspection: y2 x

Pseudo cross: R D R2' x U' R z x'

Finish XX-Cross: U R U' R' U' R U R' u'

The third pair was pretty straightforward.

3^{rd} pair: y' R U2' R' U2' R U' R'

At this point, I had to decide between solving the final pair with just 3 moves, or trying to orient all the last layer edges. Given the easy start, I thought that even if my last layer was quite bad, I still had a good chance of getting a sub 10. I decided to just insert it and take whatever LL cases came up, or potentially try and do OLLCP

4^{th} pair: y' R U R'

An easy OLL case for OH :)

OLL: U' r' U' R U' R' U2' r

Rotations before the PLL were really awkward, but I also didn't want to do AUF before and after the A permutation. I also could have done a couple of different A perm algs which may have been nicer, beginning from that angle.

PLL: x y2 U2' R2 z R' U' R z' R2 U' L U'

**9.01 seconds, 41 moves (STM), 4.55 TPS**

** **

**Scramble 5: ****L' B' R' F' B2 R D L2 F R U' L B2 D2 R2 B2 L2 F2 D2**

Yeah... this solution was really easy but I completely butchered the execution and got an 8 move LL. Not my best work :p

The start was pretty good, I tried to make a slightly tricky cross easier to execute, as well as inserted the green-white pair.

Inspection: x2

Partial Cross: z' R' F U' R U2' R

1^{st} pair: y U' R U R'

Finish cross: y U2' R2

The next pair was an easy insert, and I also saw the other two orange F2L corners right in front of me.

2^{nd} pair: U' R U' R'

3^{rd} pair: y U' R U' R' U' y z U' R' U

The last pair execution was a disaster, I wanted to orient some edges and hopefully get a ZBLL, but my solution wasn't easy to do under pressure. In hindsight I definitely should have just stuck with R & U moves with some y rotations in between.

4^{th} pair: x U F' U' F R' U' R (z' U) L

Lucky LL, but the solve was already over.

ZBLL: R' F' r U R U' z U' R

**11.24 seconds, 41 moves (STM), 3.65 TPS**

An alternative finish after pair 3 is: z' U' R' U2' R y U2' R U' R', which would have left Niklas! :/

Posted 1 week agoHow long do you think it will take for your OH WR single to be broken finally?

Simon

## zuhayr Haq

Posted 1 week agocan you do a mains and goals video for sydney champs 2017

## Cuberious The SpeedCuber

Posted 1 week agoI know that we can't improve anything from this, but can you do more of those GoPro unboxings like how you did with the GAN 356 Air?

## Feliks Zemdegs from CubeSkills

Posted 1 week agoSimon - I think there's a decent (50%) chance someone breaks it next year.

Zuhayr - probably not, I don't really do that sort of thing. Might do a mains video at the start of 2018 though :)

Cuberious - Maybe? :p

## Shankar S

Posted 1 week agoI avg 9 secs and I still get messed up while scrambling.... while practicing it really doesn't matter but for reconstructions it really does.

thanks Feliks for helping us get 1 step closer to matching u(what about that 4.75 single, any breakdown of that?)

## Khy Marchbank

Posted 1 week agoUm what does X y and z moves mean?

## Nameless Person

Posted 1 week agoKhy Marchbank it means whole cube rotations

X is like an R with the whole cube

Y is like a U with the whole cube

Z is like an F with the whole cube

If that's too confusing, then just look at the simulation on this website:
