These records are amazing, I wish I had been at this competition. Just one little problem:

I greatly respect Haiyan Zhuang, I am not trying to offend him in any way. I think this world record is simply astounding. However, the WCA regulations state: 'During the full solve the judge must keep a sheet of paper or a similar object between the competitor's face and the puzzle, unless the puzzle is in a position where peeking at the puzzle is not possible.' (Rule B4c)

His judge had no item in between his face and the puzzle for the first 13 seconds of the solving portion. He most likely couldn't be peeking, and was in a position where it was impossible for him to see the puzzle. I am almost certain that this record is valid, I just thought I should bring this up. I think the WCA Board should be sure that this record is legal. Was it possible for him to have been peeking during the execution? If it was, the result is DNF.

But that's the judge's fault for not paying attention, and I doubt he'd cheat like that.

Is it just me, or is it odd that his 3x3x3 speedsolve competition best is slower than his 3x3x3 BLD record?
he doesn't practice 3x3 anymore, so he does 3x3 speedsolves the same way he does BLD

edit:
Hi:I am Hai Yan zhuang from china. It is very nice to have so many friends here!
May be everybody here are confused with my 3*3 speed grade, why there are so many DNF. Because I use Blind method take part in the speed competition. I am very nervous during the competition. I can not stop my hand trembling. I have to give me more chance to make me do not so nervous. So I use Blind method take part in the speed competition. Everybody in china like me use this method. They give applause for me. They do not care if I waste time.

That crossed my mind also when I watched the video - the judge was not 100% perfect.

Rising the paper between the eyes and the cube did not change anything, the solver didn't even notice, the solving went on with the same speed like without the paper.

But yes, according to regulations that small mistake by the judge could cost a WR.

Also, try to step into the shoes of the judge: He has been doing the same thing maybe hundreds of times perfectly and now when he forgets this, there is a new WR. Murphys law in action. :)

Now I looked the video again. The judge does all beginning procedures and then looks around (Oh, that memorizing part is gonna take a while). Then suddenly Haiyan Zhuang starts solving. Judge realizes that a few moments later after looking around in the room and probably seeing other judges holding a paper.

The blindfold pull-down movement is also pretty quick on the left side while the judge is on the right.

So I think this is somewhat a tutorial video how easy it is to forget something very simple and very important.

I'm also positive he wouldn't cheat, and I know it's the judge's fault for not paying attention to a very crucial rule, I just wanted to be sure.

Why are you so positive he wouldn't cheat? If it's because he has a blindfold world record, I think we can all agree that that's not proven to be a very good method.

I'm not saying I have any reason to believe he cheated (I don't, and I don't think he did), I just don't think getting good BLD times is reason enough to be completely trusted. There's only a few people whom I'm completely, positively sure would not peek when presented an easy opportunity to do so. I'm not saying that anyone is dishonest, I'm just saying that I don't have any reason to know for sure for most people, especially for people I've never met.

"unless the puzzle is in a position where peeking at the puzzle is not possible"

Please pay attention to this sentence.
Haiyan's eyeshade was big enough to cover his eyes so that he can never peek the cube under his eyeshade.
As a Chinese who knows Haiyan very well,I can tell the truth that Haiyan would have been much slower if he cheated...
PS:sorry for my poor english......

INDEED.he solves much slower when he opens his eyes:)

but this bit of video evidence was the factor that provided proof beyond reasonable doubt.

No, it wasn't. I had a discussion with Tyson about this while waiting at the airport today.

But yes, according to regulations that small mistake by the judge could cost a WR.

No, it couldn't. Nowhere does it say that if the judge does not hold the paper then the solve is a DNF.

Agreed, either he wasn't cheating or he has 100% perfect lookahead without rotating or tilting the cube. One of those things is true and one is stupid, respectively.

Yea, I don't even get it. How can you solve 15 cubes blindfolded? That's just really messed up.

I am really amazed by those records. Congratulations to everyone. I didn't know China has such an amazing Multi BLD solver. I am very curious about his memo and solving methods.

He used BH Method in 3x3bld,and used both BH and 3OP in multi-bld.He told me he remembered the codes directly in multi-bld.He wants to learn Roman rooms in the near future.

Is there anyone else who can confirm that Tong Jiang actually uses BH for 3x3x3 BLD? I made the mistake of believing someone before who said Haiyan Zhuang uses BH, and later found out that apparently he doesn't. I'd hate to make the same mistake again with another solver.

It's amazing that he does 15 cubes multiBLD by just memorizing the codes directly. Perhaps that explains his incredible speed. I can't get past 11 yet with Roman Rooms. (Although my slow solving speed is part of the problem, it's not enough to account for 4 or even 5 more cubes.)

Also, a solve cannot be ruled a DNF based on video evidence.

Wrong. The main judge and WCA delegate cannot use video evidence, but the WCA board is free to use whatever they want.

Ow, BH? I see... I would also like to get a confirmation on this. Tong Jiang, please join with us in speedsolving.com. I have so much to talk with you :rolleyes:

Mr. Mike, I'm also uses Roman Rooms/Loci with an improvement on room objects interaction. With Roman Rooms, I'm very sure that we can do BLD for any n number of cubes, if we also have n number of Houses/Locis. The only limiting factor is, of course, the 1 hour limitation :)

I'm really wish to be in the same competition with you in the future, so we can compete Multi BLD on the same table. That will be a great honour for me :eek:

Why are you questioning his trust in the WR holder when you have the same trust? The reasons you don't think he cheated are probably the same reasons that Bobby doesn't think that he cheated.

Haiyan Zhuang's 35.96s bld scramble.

This is definitely not the scramble he solved. From no scrambling angle does it match http://cid-6a0225773735dfd7.skydrive.live.com/self.aspx/Beijing%20Summer%20Open%202009/DSC%5E_6608.jpg#resId/6A0225773735DFD7!662, which is clearer than, but agrees with, the videos.

(Note the four green pieces on the top in the photo.)

EDIT: qqwref found it, see below. R2 F2 D2 R' U D B U2 B' U2 F U B R F' D R2 B in WCA orientation. I might have gotten it sooner had my internet connection not been acting silly. :-/ But really, I'll start reconstructing from the vids I have.

After taking a look at a good image and the best quality video I can find (watch HQ) I believe the following scramble is the one in the world record scramble:

Yellow top, red front
L2 F' U2 B' L2 D2 U2 B2 D R' U' L' F R D F U' B' L2 (19f, probably not optimal) (view on alg.garron.us)

Haiyan solves green top, red front, by the way.


EDIT: optimal solution found! still use yellow top, red front:
F2 R2 U2 F' D U L D2 L' D2 R D L F R' U F2 L (18f*) (view on alg.garron.us).
