There is a major flaw in the rating difference system of the Endgame AI.I guess that it is not a computer program bug but a conceptual mistake.The rating difference can be set for the lobby so that the player does not see challenges that do not meet the player’s criteria.Unfortunately, this does not apply to challenges that the player creates themselves.Thus, if I set the rating range -300…+300, everyone with a rating of -500 can still see and accept my challenge.It does not make much sense because if I want to avoid players with a rating difference of -500, then I do not care who made the challenge.Moreover, when others issue a challenge, the player can see the challenger's rating in the lobby and decide whether to accept it.That is, the rating difference works where it is not urgently needed and does not work where it is necessary.Usually, the rating difference or rating range is set symmetrically to both the challenges of others and the player's own challenges.

"This week the national federations England, Norway, Estonia and Germany announced they have collectively filed an appeal with Ukraine to the Court of Arbitration for Sport against FIDE. Their complaint is about the FIDE General Assembly's decision to readmit fully Russia and Belarusia into chess team sport and allow their symbols to be used."
"The Russia/Belarus question has been bitterly dividing the chess world since, in the aftermath of Russia's full-scale invasion of Ukraine in 2022."
"The Appellants submit that the challenged resolutions were adopted following serious procedural irregularities, including violations of the FIDE Charter and fundamental principles of transparent and lawful decision-making within international sports governance."

"Czech Grandmaster David Navara has also claimed to have felt distressed and suicidal due to Kramnik's online cheating charge against him.""Kramnik has consistently defended his conduct, maintaining that his statements are substantiated."
"[Kramnik] ... now faces accusations that his own allegations against others crossed ethical and legal lines."
I am afraid that FIDE and ICCF have a mistaken voting system. Their press releases often do not specify how many deputies participated in the vote.
Their demagoguery is to say "majority" instead of "majority of those who participated".
Or they declare that "P percentage voted for the decision" instead of "P percentage of those who participated voted for the decision".
It also leads to contradictions too easily.
Already, when FIDE sanctioned Russia in 2022, public propaganda gave the impression that the majority of FIDE member states demanded the sanctions. I am afraid that, instead, it was the majority of those who voted. In any case, it seems that the percentage of those countries that supported the sanctions was much lower than the impression made by press releases.
Suppose that Y is the number of those who vote "Yes", N is the number of those who vote "No", and A is the number of those who are neutral, abstain or are missing. We assume that A > 0, as is usually the case. Then, obviously,
Y/(Y + N) > Y/(Y + N + A)
That is the basics of probability calculus and the calculus of percentages.
FIDE and ICCF public reports of their voting results are not transparent, making political demagoguery too easy.
I suggest that reports and relevant news include:
My present essay is motivated by the fact that, recently, FIDE voted on whether to annul the sanctions imposed on Russia. According to FIDE's own press releases, it managed to adapt at once two parallel decisions that conflicted with each other. See, for example:
"Chess World Left In Limbo As FIDE's Russia Vote Ends In Chaos And Confusion",
Worldchess, 14 December 2025
Quotations:
"When it came to the vote, Russia's controversial motion passed by 61 in favour, to 51 against."
"A second motion proposed by the FIDE Council also passed by 69 votes to 40."
Note that there are around 200 member federations of FIDE, and:
61 + 51 = 112 < 200
69 + 40 = 109 < 200
Note also that 200/2 = 100, and:
61 < 100
69 < 100
That is, no decision was taken with an absolute majority.
Now, let us take a look at FIDE's official statement:
"FIDE General Assembly decisions regarding Russia and Belarus",
Fide News, 14 December 2025
Quotation:
"In a procedural outcome, reflecting the diversity of views within the chess community, the General Assembly voted to adopt both the resolution proposed by the Chess Federation of Russia (61 votes in favour, 51 against, 14 abstentions and 15 delegates not voting) and the resolution proposed by the FIDE Council (69 votes in favour, 40 against, 15 abstentions and 17 delegates not voting)."
However, the total number of member states is still missing, as
61 + 51 + 14 + 15 = 141 < 200
69 + 40 + 15 + 17 = 141 < 200
I criticised the demagoguery and illogicality of FIDE's voting and its interpretations already on 24 September 2024.
