17^th International Solving Contest (ISC) 24^th January 2021

This year the ISC suffered under the circumstances of the Corona-pandemic. In many countries it was not possible to organize a tournament. But not only the pandemic led to less tournaments and solvers but also very low temperatures in Siberia (-47°C in Nizhnevartovsk) and the consequences of a severe earthquake in Croatia three weeks ago. The results of Nizhnevartovsk (the solvers solved at home) you can find as unofficial solvers at the bottom of the tables.

Finally there were 30 tournaments in 10 countries (20 tournaments in Russia). While in cat-1 it was an international contest (but only 49 solvers compared with 202 solvers last year) the contest in cat-2 and cat-3 could be also called “Russian Solving Contests” with only a few solvers from other countries.

Results: Category 1 | Category 2 | Category 3 | Statistics ISC TOP 100

Because in cat-3 the prizes for the best three solvers in the overall-category were all won by girls (perhaps an influence of the “Queen’s Gambit”?) we decided not to have special prizes for the girls but for the best boys.

At the same date there was also a home-solving tournament organized with the problems of the ISC with some top solvers. You can see the results on www.probleemblad.nl

Congratulations to the winner Danila Pavlov on his first ISC win with full points and nearly the best time.

I want to give a special thank to

• Ivan Denkovski who selected most of the problems
• Luc Palmans for preparing the problem and solution sheets
• Borislav Gadjanski for the daily update of the results on the Mat Plus website
• All local controllers for their work (most of them used STM for the results)
• Oleg Efrosinin who coordinated 11 tournaments in Russia with more than 40% of all solvers

The 16^th WFCC International Solving Contest attracted a record number of 885 participants from 47 countries. Chess composition is the art of creating and solving chess problems. Tournaments, both for composers and solvers, are held all over the world and governed by the World Federation for Chess Composition (WFCC). [→more @FaceBook]

“Now we have the completed preliminary results of the ISC 2020. The reports of the Solving Tournament Manager (STM): Preliminary results Cat.1 | Preliminary results Cat.2 | Preliminary results Cat.3

This year we had 885 solvers (cat-1 202, cat-2 241, cat-3 442) from 47 countries and 48 tournaments in 31 countries.

Thank you to all local controllers. You make this tournament to a great success.

I want to give a special thank to

• Ivan Denkovski, Luc Palmans, Marjan Kovacevic and Neal Turner for selecting the problems 
• Luc Palmans  for the preparing of problem and solution sheets.
• Borislav Gadjanski for his help with all activities concerning Mat Plus and daily updates of results on Mat Plus
• all Local controllers who uses the STM for their results”

Axel Steinbrink, Central controller of ISC 2020.

The first ISC was organized in 2005 and was an immediate success. …more →

The idea of a multiple locations solving tournament was appealing, but there was also some scepticism. Of course, there were some issues, because everything was new. With trial and error in the next years the rules were slowly established. Internet, e-mail and social media made life of the controllers more easy. The Solving Tournament Manager, created by Misha Mladenović, is an incredible aid. But also the websites of WFCC (Julia Vysovska) and Mat Plus (Borislav Gadjanski) are pivotal for our competitions. We take this all for granted, but too quickly we forget all the hard work it takes.

Every year the first category of ISC welcomes some 200 solvers, many of them the best of the world. Winning this prestigious tournament is only for the happy few. The second category is much liked because the less experienced or occasional solver can enjoy a nice day of solving close at home, and still compete against the rest of the world. The introduction of a third category for kids proved to be a spark of genius. Thanks to the efforts of some local controllers, several hundred kids were this year introduced to problem chess.

The 16^th edition of the ISC will be in many ways a marking point for future tournaments. Experienced solving directors provided us with interesting problems, which lead to a selection of quality problems to solve. Especially Ivan Denkovski should be mentioned, because his review of the final proofs avoided some embarrassing errors.

We can’t praise enough the central controller Axel Steinbrink for his hard work, and without him the tournament would not be such a success. He developed the rules and the procedures of this complicated competition. As you all could witness in the past days, the tournament ran smoothly, with daily updates of the results, and a minimum of complaints. One reason of the success of this year (almost 900 solvers!) is undoubtedly that the ISC is such a well organized competition.

Everyone who was ever involved in a WCSC or ECSC-championship knows how hard this work can be: supervising several hours the competition, and then marking a few hundred solving sheets in the remaining hours, while all the solvers impatiently wait for the results. But this cannot be compared with the ISC. In the past days, Axel not only collected all the results and made all the rankings. Most of all he meticulously checked the more than 1300 solving sheets “with terrible handwriting, and corrects tens of careless local controllers” (dixit Marjan Kovacević). Thanks, Axel!

Finally, we thank all the participants for their efforts, congratulate the winners, and look forward to the 17^th edition!

This year we have nearly 900 solvers in 31 countries who participated in the 16th ISC.

This is the preliminary TOP10 result:

Axel Steinbrink, Central controller of ISC 2020, informs:
“At the moment we have 32 countries with 43 tournaments all over the world“

The International Solving Contest – ISC – next year will take place on Sunday January 26^th 2020. The event is happening simultaneously in all participating countries. The name of the locally appointed controller must reach the central controllers Axel Steinbrink and Luc Palmans by e-mail no later than December 31^st 2019:  axel.steinbrink@gmx.de  / palmans.luc@skynet.be

There are two changes of the rules compared with ISC 2019:

1. The rating limit of Cat-2 is now 2000 (1700 in 2019) and cat-2 will be rated. Of course the birthday limit of cat-3 is now 31.12.2006.

2. The results will be automatically transfered to the MatPlus-website where they can be seen by all solvers. This means that there is no need anymore to enter results manually into MatPlus.
But top 3 results of Cat. 1 must still be sent by email to central controllers on Sunday evening!

I hope that even more local controllers will use the official WFCC Solving Tournament Manager (STM) for their results.

Until 31.12.2019 please send the following information: 

1. Name of local controller
2. E-Mail address of local controller
3. Location of local tournament
4. Use of STM: yes/no
