FIDE player card for Hans Niemann

(born Jun-20-2003, 19 years old) United States of America

[what is this?]

Hans Moke Niemann was born in San Francisco, California, moving to the Netherlands at the age of 7 for a few years before moving back to the US and eventually graduating from Columbia Grammar & Preparatory School, which is known for its chess culture. He was awarded the Grandmaster title by FIDE on January 22, 2021. On March 1, 2019, Niemann first entered the Top 100 Junior players list on position 88. As of November 2021 he is ranked 9th (Juniors ranking) and 124th (Open ranking) At the 2015 National Open of the Las Vegas International Chess Festival, then 11-year old Niemann became the last person to play a rated game against GM Walter Browne, who died shortly after competing in the tournament. Browne won in 35 moves.

After initially winning his first 6 consecutive games, Niemann finished in third place at the 2018 U16 Olympiad in Konya, Turkey. In December 2018 he won the National K-12 Blitz Championships undefeated, finishing 12-0.1436 Three days later he went on to tie for 1st in his grade in the overall K-12 Grade Championships,37 while also tying for first in the bughouse duo,38 achieving a perfect win.11

in June 2019 Niemann won the inaugural ChessKid Games hosted by, accruing 20 straight victories and qualifying for the 2020 Junior Speed Chess Championship.Niemann achieved his third and final GM norm at the Charlotte Chess Center & Scholastic Academy (CCCSA GM Norm Invitational) in October 2020, placing first.

n July 2021 Niemann finished 1st place in the World Open held in Philadelphia, after beating John Burke in a tiebreak playoff. It was also in this tournament that Niemann surpassed the 2600 threshold with a draw against Ukrainian grandmaster Illia Nyzhnyk in Round 8. Later that same month Niemann won the U.S. Junior Championship held in St. Louis, which entitles him to compete in the invitational 2022 U.S. Chess Championship.

Niemann's third-round win against World Champion Magnus Carlsen in the Sinquefield Cup (2022), and its aftermath, engendered worldwide controversy, even in the non-chess popular media. The day after the loss, Carlsen withdrew from the tournament, an extraordinary action in a premier round-robin event. Carlsen announced his withdrawal in an enigmatic tweet in which he indicated that he would get in trouble if he said more. This was widely interpreted as an insinuation that Niemann had cheated. Niemann responded with an impassioned interview in which he denied ever having cheated in over-the-board chess, although he admitted having done so several years earlier in online chess. Extensive analysis of Carlsen vs Niemann, 2022, including by anti-cheating expert IM Kenneth Regan, found no evidence that Niemann had cheated. Two weeks later, Carlsen resigned a game against Niemann after just one move. Carlsen later gave an interview in which he stated that he believes that Niemann has cheated more often and more recently than he has admitted.

  MissScarlett: Niemann scored +1 at the US Champs over 13 rounds (U.S. Championship (2022)) , and +1 at the Fall Classic over 9 rounds (Fall Chess Classic (2022)).
Nov-29-22  Bobby Fiske: Thank you <Scarlett>. (Memo to myself: Always refer to when digging into details). So here is my post, updated:

Here is a summary of all his <22> games, from his 2 last tournaments. TRP calculated with the simplified ± 400 win/lose formula:

R1-R3: = TRP 3059
+2 in 3 games. Drew Aronian, beat Shak and Magnus.

R4-R9: TRP 2634
-2 in 6 games (move delay from R4)

+1 in 13 rounds (move delay all rounds)

CONCLUSION: His performance dropped considerably in the 19 games played with move relay delay.

You might say the numbers are too few for statistical significance, and that Hans is not performing at his best after all the publicity. That’s why time will be the final proof.

Premium Chessgames Member
  MissScarlett: What was the TPR for the Fall Classic? Then calculate the overall rating performance for the 28 games since the defeat of Magnus. Compare that with the 28 games he played prior to the Sinquefield Cup.
Premium Chessgames Member
  beatgiant: <Bobby Fiske>
Everyone thinks statistics is simple.

It's not valid to cherry-pick his 3 best games in a row and expect him to perform at that level constantly. Try applying that test to some other GMs and you'll "discover" a lot more "evidence of cheating."

Nov-29-22  stone free or die: I don't understand the interpretation of the US Championship results:

It seems to me that Niemann performed near 2700 level (2699), when the original assertion was that he's dropped back to being a "2600 player".

Super-GM might be slightly ill-defined, but isn't it generally taken to mean 2700+?

I would say that Niemann is still knocking at the door, despite the "improved" anti-cheating measures, and the turmoil of the Sinquefield Cup.

Nov-29-22  stone free or die: <<Missy> What was the TPR for the Fall Classic?>

Go to Niemann, click on the magnifying glass and you'll see the effect of the Fall Classic on his rating, -0.5.

Pretty sure this means his TPR is essentially the same as his current rating - i.e. a tad less than 2698.5.

Premium Chessgames Member
  perfidious: <zed>, quite so; Niemann performed more or less to expectation.

The bit re 'dropped back to being a 2600 player' is risible; when Niemann climbs over that elusive barrier of 2700, will he magically become elite again?


Nov-29-22  Bobby Fiske: <<beatgiant> It's not valid to cherry-pick his 3 best games in a row and expect him to perform at that level constantly.> It's not cherry picking. Those first 3 rounds are the games who fuled the whole controversy. Comparing the results before/after the organizer started to delay the move transmission is interesting. Statistically, it fits the picture if you think Hans cheated.

<Try applying that test to some other GMs and you'll "discover" a lot more "evidence of cheating.> OK. Pls show us an example.

Premium Chessgames Member
  chancho: For someone who says <he'll let his chess speak for itself,> his results have been not so meteoric but more like sophomoric.

The guy is not the next Bobby Fischer.

And as far as the lawsuit, I've seen Magnus grinning like a cheshire cat.

Doesn't look worried at all.

The Niemann effect seems to be losing its luster.

Nov-29-22  nok: We need more math illiterate posts.

Hans Niemann (kibitz #509)

Premium Chessgames Member
  perfidious: Better math illiterate than utterly lacking in decency and humanity, as is the case in certain quarters.
Premium Chessgames Member
  fredthebear: Like you're one to be judging others.
Premium Chessgames Member
  beatgiant: <Bobby Fiske>
< It's not cherry picking. Those first 3 rounds are the games who fuled the whole controversy.> Carlsen started the controversy after Carlsen lost a game. You consider that a valid statistical criterion?

<Pls show us an example.> I don't have time to do this right, but let's take a quick look at some players close to Niemann on the rankings, then.

Sargissian, Round 6-Round 9 of Chennai Olympiad had 3 wins and 1 draw versus Caruana, Harikrishna, Abdusattorov and Mamedyarov. Chennai Olympiad (2022)/Gabriel Sargissian

Deac, Round 1-Round 3 of Superbet Romania had 2 draws and 1 win versus Nepo, Aronian and Rapport. Superbet Romania (2022)/Bogdan-Daniel Deac

Artemiev, Round 16-Round 18 of Meltwater Finals had 2 wins and 1 draw versus Carlsen. Meltwater Tour Final (2021)/Vladislav Artemiev

Keymer, Round 5-Round 7 of Grand Prix Berlin had two wins and a draw versus Dubov, Dominguez Perez, and Mamedyarov. FIDE Grand Prix Leg 3 (2022)/Vincent Keymer

Even without doing any math, it should be obvious from the above that it often happens that a player rated around 2700 has a performance much higher than 2700 for a small number of games in a row.

Nov-29-22  stone free or die: What's that cliche I always trundle out?

<A number without an error-bar is a lie>

This is, of course, numbers in the real world - that of measurements and statistics.

We've been fudging here, never mentioning how reliable our calculations are. I think this is a casual discussion, where it's understood that TPR's are mostly just indicative, and not definitive.

But there's an implicit understanding even when using it as an indicator - the TPR is meant to be calculated for the entirety of a tournament - usually requiring 9 or 10 or more games.

I think using just three games for a TPR is far too few games, and really not usable even as an indicator.

When <BF> asked for examples, I immediately thought of Caruana's super-human <SinqueField Cup> performance a few years ago. But I believe <beatgiant>'s examples are even better - selecting 2700 threshold players - to demonstrate the fluctuations in performance over just a small handful of games.

Nov-29-22  Bobby Fiske: <beatgiant> Seems you missed the main point:

Ofc 3 games alone, is not enough for statistical measures, but here they are combined with an additional factor: Starting from R4 the move transmission was delayed 15min. Hans' TRP performance dropped 400 when players got isolated from spectators.

Premium Chessgames Member
  beatgiant: <Bobby Fiske>
If you agree that <3 games alone, is not enough for statistical measures> then what basis is there in the claim that his performance in the first 3 rounds (which you agree we can't use to estimate his strength) is higher than round 4 and beyond?

But yes, I have seen discussions of the claim that Niemann performed better when there's no delay in transmission. From what I've seen, the claim falls apart when examined carefully.

Premium Chessgames Member
  MissScarlett: <Ofc 3 games alone, is not enough for statistical measures, but here they are combined with an additional factor: Starting from R4 the move transmission was delayed 15min.>

This is why I enquired after the corresponding 28 games he played before the Sinquefield Cup. As far as I know, there were no transmission delays at these events. Unless you're proposing that Niemann never cheated OTB before Sinquefield, what happens if Niemann's recent performance is equal/superior to his pre-Sinquefield results?

Nov-30-22  stone free or die: I think <Missy> has asked herself [sic?] a valid question.

Get on it, <Missy>!


Premium Chessgames Member
  perfidious: <zed....I think using just three games for a TPR is far too few games, and really not usable even as an indicator....>

This is all fluctuation and, as you say, demonstrates nothing except how cherry-picked numbers can be used to prove, or disprove, a point anyone is trying to make without imparting actual value.

Nov-30-22  stone free or die: BTW - when I google the <Niemann Effect>, I got this:

Premium Chessgames Member
  fredthebear: Did you "Get on it, <Missy>!"?
Dec-01-22  stone free or die: Don't forget to turn off the lights.
Premium Chessgames Member
  perfidious: Having got a public slapdown after a post which almost contributed on the chess side of things, yet could not help lapsing into trademark acerbity while being typically disingenuous, someone hereabout is evincing a sententious side.

Meanwhile, I am still waiting for my cut of the $100m judgment.

Might be a long wait. (laughs)

Dec-01-22  supy: He is currently playing Llobregat with Vallejo, Yu Yangyi and Cheparinov
Dec-01-22  EvanTheTerrible: He has crossed 2700 for the 3rd time on the live list. Let's see if it sticks this time.
