Carlsen withdrawal after loss to Niemann

[Chessqueen]

You think? Care to share any reference?
I’m guessing you are not a statistician or data scientist.

Your guess is based on what? Statisticians or data scientists do not think? Do you have a reference for that?

It's a logical conclusion for me, feel free to disprove. Or just let it stand as an opinion, it's not really important for the topic.

If there is no strong correlation between rating and aCPL, the whole aCPL argument about cheating falls in the water. So, any references, or just your thinking?

I had to beg off this thread for a couple of days because of the general distasteful tones and cheerleading...but saw this and wanted to mention that I watched Daniel Naroditsky's stream last night and he was very clear that he has changed his initial thoughts about Hans cheating OTB. He addressed all the 'data/stats' being thrown around out and the data may be fine, but....saw 'confirmation bias' written all over them.

With that said...back to my castle of quiet contemplation.

GM Caruana trolled Hans by blitzing and waited to see if GM Hans played fast which will not give Niemann any time to cheat, but Niemann did this instead ==>

[Graham Banks]

Teenage U.S. chess grandmaster Hans Niemann appeared to receive a more thorough security check than other players on his arrival at the U.S. Chess Championships in St. Louis this week.

A St. Louis Chess Club livestream showed Niemann, 19, being asked to turn around so the security wand could be waved over his buttocks as he entered the competition arena. But the two players before Niemann and the one after him were only scanned on their fronts.

I saw the scans and definetly there was no ass checking! I think if cheating is involved it probably is a lot less sophisticated than most people are thinking of. I remember with Ivanon, he accepted to go through a CT scan to see if he had any embedded electronics inside his body. Of course all that did was that it made him look more innocent as nothing was found. You would think that someone that has no problem doing a CT scan would alos accept removing his shoes ... but apparently not! Somehow people think that if you go through an electronic scanner that means there are no electronics on you. Ivanov would always pass electronic screening and so people started thinking of many exotic ways he could be using a sophisticated devices. I think for sure that if there is enough prize money involved, someone will try to circumvent whatever cheating protocols are used. It is highly doubtful that a novice chess player can get away with it as he wouldn't be able to make sense of the moves he plays and a few key moves are not enough for him to play out the game. Most GM's however, have enough good technique where they can win a "won" game or at least can win when they have a huge advantage. If Hans Nieman is cheating, it is probably in a way that is much more simple than most are thinking about. If he is cheating, he certainly is not cheating in every game as some of his games are of very poor quality for his supposedly "best chess player in history of chess" standard.

Lol ... that was definetly not an ass check

Well what do you expect?

I don't think that anybody is going to be allowed to stick anything up there, and rightly so, unless other participants are searched in the same manner.

GM Hans should request a lie detector like the Ukrainian chess champion requested ==>

You completely misunderstood:

the data is quite convincing, because the correlation gives consistent picture between different players and different periods.

Maybe I didn't express myself correctly, I am not a native english speaker...

I think the correlation increases with the playing strength.

I mean the correlation of the acpl between different players of the same strength. The data you showed has more variety, but was made with low rated players. I think, the acpl of low rated players has more variety as of strong players. Its a logical conclusion and our data also show that.

You shouldn't point to others when speaking about "distasteful tones". No one is "cheerleading" here.

Hans should accuse Caruana of using an engine, since GM Caruana played like a Machine ==>

Actually that was not one of Caruana's better games. Caruana is one of the people that have indirectly accused Hans of cheating OTB with quotes like "either he is an alien or something is fishy" and "these moves are above my level". There is a podcast where he goes through some of Hans suspect games and it really is fascinating how he allows people to see how a 2800 GM thinks. I am sure that if you have even the slightest doubts that your opponent is using SF 15 NNUE, your game will be played differently. Interesting to note that in his interview post game, Caruana did mention that he and Hans are no longer on speaking terms.

Where is this analysis? Mr. Milk (or the “Brazilian” as you like to call him) has not made such a far ranging study.

Was it AlphaZero or GM Hans ? ==>

Was it AlphaZero or GM Hans ? We have to give thanks to GM Hans to allow us to see how an engine X can crush Magnus Carlsen, since Magnus refused in the past to play versus any Top engine, but GM Hans did it very cheap for us to witness without having to pay Magnus Millions like in the case of Kasparov vs Deep Blue ==>

Note: Some billionaire Like Elon Musk should pay GM Hans at least 5 million to reveal all the games in which he used engines to crush GMs
