PRESENTATION of ISC results


The 20 years of ISC (2005-2024)

The idea to organize the International Solving Contest, simultaneously in many countries, came from Uri Avner in the year 2003. After a period of preparation the 1st ISC was held in January 2005. The winner was Roland Baier (SUI) and Ward Stoffelen was the Central controller. With 27 tournaments in 23 countries and 262 solvers it was already the greatest solving tournament in history.

After the success of the first edition, it was decided that the next tournament in 2006 should be rated, and that a second category for less experienced solvers should be included. In the following years ISC became a standard in the second half of January and the number of participants grew until more than 400.

In 2015 a third category for kids under the age of 13 was established. The record number of participants was reached in 2020, with 885 solvers in 31 countries. Later on, the regularity of ISC wasn’t interrupted even during the Covid crisis. The ISC became an opportunity for many solvers around the world to compete and get initial ratings. Also, nearly all top solvers have been using this tournament to test their skills. The record holder is Piotr Murdzia (POL) with six wins in the 1st Category competition.

Central controller of 14 ISC tournaments

Happy New Year 2023!

The year behind was crowded with official composing and solving events, thanks to the judges and organizers who worked hard in 2022.

January brought 18th International Solving Contest, another successful edition run by ever passionate Axel Steinbrink.

In March, the Solving Committee has made another step forward, introducing the very informative Solving Portal on our website.

May was the month of 15th European Chess Solving Championship, and Julia Vysotska created and exceptionally friendly atmosphere in Riga to attract solvers to the first ECSC since 2019.

Results of the two longest lasting composing events were completed between August and October. First, Valery Kopyl finalized the 8th World Championship in Composing for Individuals 2019-21, in spite of the most difficult circumstances in his country.

The other hard task was fulfilled by our long standing President Harry Fougiaxis, who took over the duty of the 11th World Chess Composing Tournament director.

During the summer, awards of the 10th FIDE World Cup in Composing were appearing one by one. In October, the director Aleksey Oganesyan ended his job and announced the final results.

World Solving Cup 2021/22, under the firm control of Roland Ott, lasted throughout the year, using the organizing resources of 13 different countries.

The final stage of the WSC was in Fujairah. In November, the United Arab Emirates hosted the 64th World Congress of Chess Composition. The first ever WCCC in Arabian Peninsula was an outstanding event in many ways. Dr. Abdulla Ali Aal Barket assured the memorable conditions for promotion of chess composition, and Mohammad Abdul Ghani was there to execute every single task.

The director of the 45th World Chess Solving Championship was the same as for the 15th ECSC. It was a challenging double task, unmistakably executed by Ivan Denkovski.


Let’s turn to 2023!

The red dates in our calendars will be 29th January (19th ISC), 2nd-4th June (16th ECSC in Bratislava) and 2nd-9th September (65th WCCC in Batumi).

Apart from regular competitions, we will have a joint duty to come closer to a much wider audience. The first steps in this direction were made a week ago, registering the WFCC in different social media (YouTube, Facebook, Twitter, LinkedIn, Instagram), with some introductory posts for each of them.

To find our stable place there we need more contributors from different countries, to “feed” the media with short but attractive and frequent posts. Some longer posts, for instance from national championships, may appear on the FIDE website, as announced by their Marketing and Communications Officer David Llada.

It’s perhaps time to recall words by our Honorary President Dr. Klaus Wenda, dedicated to the Golden Jubilee of our organization, in 2007:

There is no doubt that the status of the contemplative occupation of chess problems among the young is lower nowadays; that is confirmed by an alarming lack of young problemists in virtually all the member countries. It only makes the task of the commission more important, though: creating new incentives and new ways to arouse interest in chess composition. I know that there is no easy answer, but the important thing, in accordance with Herakleitos’s dictum, is to recognise new trends quickly and react to them appropriately.

Happy, healthy, and peaceful 2023!

Marjan Kovačević
WFCC President
