Recent world news

As I had made a long break from blogging, I have decided to make a short summary of what interesting has happened meanwhile that may not be (but definitely should be!) widely known yet. I have decided to separate it into two parts: "Recent world news" and "Recent European news".

RECENT WORLD NEWS   FIDE has decided to create separate rapid and blitz rating lists starting from January 2012. That's a warmly expected news. It is hard to believe, but the main reason why FIDE didn't take that decision earlier was financial, not logistic. The amount of received tournament reports can be huge, however FIDE Rating Office in Elista works surprisingly well. They would be even able to produce rating lists on daily basis, had organisers (especially from continents other that Europe) sent tournament reports on time. FIDE tried with a rapid list a decade ago, but failed due to financial reasons. Neither players nor organisers wanted to pay extra fees for FIDE. Having a choice between no list and a list with no financial profit, FIDE officials opted for the first solution. According to FIDE announcement, in 2012 no fees will be charged, while "Decisions concerning any charges for either tournaments or players from 1st January 2013 will be made at the FIDE Congress in Istanbul in 2012. Federations are reminded that it will be possible to remove players from the new lists if the financial burden causes them too many problems.". More information can be found here. Talking about ratings, I warmly encourage everybody to read the following publication: K.~Regan, B.~Macieja and G.~Haworth: "Understanding Distributions of Chess Performances,'' PDF file of 11/23/11 current version, in revision for 12/15/11 final copy. (Older version with pre-1971 historical rating estimates.) Abstract: This paper presents evidence for several features of the population of chess players, and the distribution of their performances measured in terms of Elo ratings and by computer analysis of moves. Evidence that ratings have remained stable since the inception of the Elo system in the 1970's is given in several forms: by showing that the population of strong players fits a simple logistic-curve model without inflation, by plotting players' average error against the FIDE category of tournaments over time, and by skill parameters from a model that employs computer analysis keeping a nearly constant relation to Elo rating across that time. The distribution of the model's Intrinsic Performance Ratings can hence be used to compare populations that have limited interaction, such as between players in a national chess federation and FIDE, and ascertain relative drift in their respective rating systems. The Association of Chess Professionals is organising the General Assembly with elections to the board. Let me remind you that according to the ACP Statutes: "The ACP is run by a board of 9 members. The Board's function is, among others, to initiate debates concerning official tournament rules, proposals to improve professional players' conditions, to search for sponsors in order to organize tournaments under the aegis of the Association, to establish the agenda of the Ordinary General Assembly, etc. This list is not exhaustive. Members already holding another post in an international chess federation cannot be elected to the Board. There should be at least one male and one female representative in the ACP Board." More information can be found here. "Recent European news" will come up soon.
