§5 Proposals by Members

5.I Proposal by M. Kovacevic (WCSC):
Marjan Kovacevic‘s proposal to allow a female and a junior solver (under 20) to compete in the WCSC in addition to the present 4-solver-rule was supported by the subcommittee. A discussion on practical consequences of such an amendment ensued. Although such a broadening of the WCSC would cause extra organisational effort which should not be institutionalised, Hannu Harkola considered it a good idea provided the organizer feels he can deal with the extra work. No formal decision was taken by the Commission.

5.II Proposal by Great Britain (solver norms):
Following Great Britain’s proposal to establish a system for gaining solving norms in other tourneys than the WCSC, as submitted in 1995, the subcommittee presented to the Commission a set of proposals identified as „Criteria for gaining norms“,  „Criteria for gaining titles“, „Criteria for adequateness of the tournaments at which ratings can be gained“ and „Solvers rating“ (see annex). It was pointed out that the conditions for obtaining norms or titles are intentionally drafted such that it is really difficult to fulfil them. The Commission should nevertheless strictly observe the tournaments in order to avoid any possible abuse.
In the ensuing discussion, it was pointed out that there are at least two rating systems available (Kolcák and RELO) and the question arose which system should be used. No decision could be taken during this meeting because the mathematical details of the systems were not available. (A paper „Rules for rating calculation“ by Marek Kolcák is annexed to these minutes.) A working group consisting of Marko Klasinc, Harri Hurme, Marek Kolcák and Henk le Grand should further consider the systems and make a proposal until next year’s meeting.
Although a formal decision could not be taken, the Commission had a strong tendency to accept the proposal provided a suitable rating system, which should then be officially approved by the Commission, is available.

5.III Further proposals
Further proposals were discussed in various subcommittees and are referred to under other paragraphs of these minutes (§6 Competitions, §7 FIDE-Album, §8 Qualifications).

6.II 6th WCCT
On behalf of the tournament director Hemmo Axt (not present), Günter Büsing informed the Commission about the state of the tournament. Although it was originally expected to present the final results during this meeting, the results in three sections were still missing. Two of the judges, who were present, confirmed to be almost ready and to present the award very soon. One award was said to have been mailed two months ago but had not arrived. The delegate of the corresponding country was asked to remind the judge to resend the award.

6.III  Future WCCTs
The 7th WCCT, which will be the first to be organized under the new judging system, will presumably be announced in 2001. Macedonia suggested to organize it and Zivko Janevski was generally accepted by the Commission as the tournament director.
Themes for each section are needed and must be fixed during next year’s meeting. Uri Avner informed the Commission that the subcommittee intends to invite specialized persons to make proposals but in addition thereto everyone was invited to submit theme proposals directly to him. Guidelines for what is considered a good theme were presented by John Rice. Accordingly, a good theme should not be too easy but also not so difficult that less talented composers are discouraged. It should further allow the composer to introduce strategic play, and it should not be closely associated to a preferred style of a specific country or composer.
After discussion with the delegates of the prospective countries, a preliminary list of candidates for judging countries, with a maximum of three sections to judge for any individual country, was established. Each judging country needs a contact person who is responsible for the contact between the country and the Commission. It was agreed that this contact person should be the delegate of that country unless the country appoints an other person.
A proposal by Marko Klasinc to organize the WCCT on a regular 3-year basis was postponed for the time being because some experience with the new system should be made before such a decision is taken. Jakov Vladimirov pointed out that more judges are involved in the new system and that a strict time table should be followed in order to assure that the tournament will be finished within a reasonable period of time. He suggested that the director of a section might judge in place of a country which does not present its judgement in time. This question was given to the subcommittee for further consideration.
The judging method was discussed, the alternatives being a) each judging country establishes a ranking order of the competing compositions, or b) points are given to each composition. Both systems have some advantages and disadvantages and after consideration the subcommittee suggested to adopt the point system. Some minor questions, e.g. whether the points given by the individual countries, or the total point score, or only the final ranking should be published in the award, still have to be considered. No formal decision on the specific judging method was taken by the Commission.

6.IV WCCI
Subcommittee spokesman Marko Klasinc presented to the Commission a draft for general rules for organizing the World Championship in Composing for Individuals. The draft (see annex) is based on the decisions taken during the 1999 meeting and was accepted by the Commisison in a vote (20 in favour, 3 abstentions, 0 against).
The announcement of the WCCI for the period 1998 - 2000 has been prepared with the exception of some judges who have not yet been found. Marko Klasinc will act as tournament director and the presidium will approve the list of judges once it is finished.
The announcement for the WCCI 2001-2003 is also under preparation.

§7 FIDE-Album, Report by the Subcommittee

7.I FIDE Album 1986-1988
The spokesman Kjell Widlert informed the Commission that the reprint in three languages will presumably be available by the end of 2000. Copies of the album 1989-1991 are still available.

7.II FIDE Album 1992-1994
Last results arrived with the editors in June 2000. It is hoped that the album will be published in 2001.

7.III FIDE Album 1995-1997
Work on the album is running and there is some hope that it might be ready until 2005. John Roycroft indicated that the final number of entries in the study section is 640 instead of the previously announced 586. He regretted that there were many very late entries.

7.IV FIDE-Album 1998-2000
Judges and directors for this album period were selected during the meeting. Subject to approval by the non-present candidates, the album will presumably be announced in early 2001, with a possible closing date before the end of 2001.

7.V Proposals
A proposal to divide the helpmate section into two sub-sections was discussed in the subcommittee. For the time being it was not deemed necessary to divide the section because the judges nominated for the next album period are willing to judge the whole section.
A revision of the guidelines for album judges is in preparation and will be distributed to the directors and judges of the album 1998-2000.

Spokesman Günter Büsing reported to the Commission that the subcommittee recommends the preliminary draft for an introduction as annexed to last year’s minutes to be published provisionally, e.g. in the internet or in the PCCC booklet as there is presently no need to modify the codex.
The subcommittee intends to keep the working of the codex under review and to take account of any criticism or comments, which should preferably be addressed directly to the spokesman.

§10 Computer Matters, Report by the Subcommittee

Thomas Maeder gave a report on the activities of the subcommittee for computer matters which had concentrated on three points:

1. He referred to a proposal from Macedonia that the PCCC should officially approve a database project for collecting personal information of problemists (name, age, etc.) and of publications. In view of the subcommittee, this project was not yet in a state to be approved officially although it was considered as interesting. Zivko Janevski, who is the contact person for the project, confirmed that the database will be generally accessible without charges. However, the Subcommittee encourages problemists contacted by the Macedonian team to contribute to their work. The question whether to declare the collection should be considered again once the PCCC will have been presented first results of the work.

2. With reference to the questionnaire related to problem collections, distributed last year, discouragingly few responses have been received. He suggested to distribute the questionnaire in further countries.

3. Thomas Maeder referred to the PCCC mailing list and offered to provide further mailing lists, e.g. for some subcommittees, if desired.

§11 Studies subcommittee

John Roycroft reported to the Commission that the studies subcommittee had selected the "study of the year" for the years 1995, 1996, 1997. These are studies by G. Ya. Slepyan (Szachista 1995), O. Pervakov (1st Pr. Jub.-Ty. B. Gusev 1996) and M. Matouš (2nd Pr. ?S. Šach 1997).
John Roycroft emphasized that the purpose of the proclamation of the study of the year is to publicise studies. He therefore asked the delegates to maximize publicity of the studies of the year.

§12 Future Meetings and future WCSC

Invitation 2001: The invitation by the Dutch Federation to have the meeting in Wageningen, which had been accepted during the previous meeting, was confirmed and a date (July 28 to August 4, 2001) and location for the event was announced by Henk le Grand.

Further Invitations: Invitations for the 2002 meeting were presented by the Slovenian and the Ukrainian delegates. After discussion, the Ukrainian proposal was shifted to the year 2003. The Commission decided to accept the proposal of Slovenia to organize the meeting 2002 in Portoroz (presumably from 31.8.-7.9.2002) and also to accept the proposal of Ukraine to have the meeting 2003 in Truskavets.

§13 Any other Business

13.I Yochanan Afek proposed to add 2 special prizes in all solving tourneys: a junior prize for the best under 20 solver and a veteran prize to the best 60+ solver.

13.II Yochanan Afek noted that many players are interested in chess composition and therefore proposed to send results of events such as solving competitions and the „study of the year“ selection to the two most popular internet sites: Kasparov chess and TWIC (The week in chess). most chess players visit those sites and the material would be warmly welcome.

13.III  John Roycroft suggested that awards in quick composing tournaments should not be taken into account by the qualification committee in applications for the title of an international judge. The proposal was forwarded to the qualification subcommittee.

13.IV  Marko Klasinc suggested to organize a solving show at chess olympics or, in view of the contacts between FIDE and the Olympic organization, even at Olympic games.

As there was no further other business, the President finally expressed his thanks for the good work of the delegates, the Secretary, the subcommittees and the organizers of this meeting, and then declared the meeting closed.

 Annexes:

- (Studies of the Year 1995, 1996, 1997)
- World Championship in Composing for Individuals – General Rules
- Criteria for gaining norms & Criteria for gaining titles
- Solvers rating & Criteria for adequateness of the tournaments at which ratings can be gained
- Rules for rating calculation (Kolcák)
- (List of addresses)

1. The WCCI is organized with the authority of the PCCC - FIDE. The championship should be announced in advance.

2. The WCCI is open to all composers from all member federations of the FIDE.

3. The WCCI includes the following sections: a) Twomovers, b) Threemovers, c) Moremovers, d) Endgame studies, e) Helpmates, f) Selfmates, g) Fairies and h) Retro problems.

4. Three judges in each section grade the compositions. The PCCC gives instructions on the choice of the judges. Only competent judges, with the title "International Judge of the FIDE for Chess Composition" will be invited to make the awards. The final choice of the judges and the Tournament Director lies with the PCCC. The judge cannot participate as competitor in his section, but he is free to enter all other sections.

5. A composer may send in each section max. six compositions, published in a defined three years period. Corrected compositions or versions may participate in a period when they are published. Joint compositions are not allowed. It is not allowed to send compositions for somebody else. The best four compositions count for the final result.

6. Entries should be in five copies, stamped on uniform diagrams, with the author's name, publication data with eventual reward, stipulation and full solution clearly written on the front of each diagram, and eventual comment. The algebraic notation is to be used. Compositions should be send to the Tournament Director. He sends them to the judges.

7. The judge gives marks to all compositions according to a 0 - 4 scale (with the same criterion as for Album FIDE). He sends marks to the Tournament Director. Judges may exclude incorrect or anticipated compositions from the tourney with the agreement of the Tournament Director.

8. Tournament Director calculates the results. The final mark of the particular composition is an average of the marks from all three judges. The final mark is rounded on two decimals.

9. A sum of a composer's four best compositions is calculated for his final result. A champion in each section becomes a composer with the highest sum of his best four compositions. In a case of equal final results the better highest ranked composition decides. If they are still the same, the second ranked composition decides, etc. If all compositions have the same marks, composers share places.

10. The results of all composers are announced in the final report. The compositions (the best four) with eventual comments should be published for at least three best composers in each section. The three compositions with the highest marks in a section should also be published if they not belong to the winners. The official documents (announcement and award) should be written in at least one of the official languages of the FIDE. The PCCC decides about the publisher of a booklet.

11. The three best composers in each section should be awarded a Certificate of Honour.

At least 5 solvers with the obligatory qualifying rating (2400 for FM, 2500 for IM, 2600 for GM) should compete at the tournament.

A norm for the International Solving Grandmaster of the FIDE: To obtain a norm a solver must score at least 90 % of the winner's points. With the exception of the WCSC he must take the place within the number of solvers with the rating at least 2600, but not lower than tenth place (i.e. at least sixth place in case there are six solvers with rating 2600 or higher). At the official WCSC a solver must take one of the first ten places regardless the ratings.

A norm for International Solving Master of the FIDE: To obtain a norm a solver must score at least 80 % of the winner's points. With the exception of the WCSC he must take the place within the number of solvers with the rating at least 2500, but not lower than 15th place. At the official WCSC a solver must take one of the first 15 places regardless the ratings.

A norm for FIDE Solving Master: To obtain a norm a solver must score at least 75 % of the winner's points. With the exception of the WCSC and PCCC-Open he must take the place within the number of solvers with the rating at least 2400, but not lower than within the top 40 % of the solvers. At the official WCSC and PCCC-Open a solver must take one of the top 40 % places regardless the ratings.

International Solving Grandmaster of the FIDE: A solver must gain a norm 3 times (at least once at WCSC) within a period of ten years.

International Solving Master of the FIDE: A solver must gain a norm twice (at least once at WCSC or PCCC-Open) within a period of five years; or score once 100 % of the winner's points and qualify within the first 15 places at the WCSC.

FIDE Solving Master: A solver must gain a norm twice, or score once 100 % of the winner's points and qualify within top 40 % places at PCCC-Open (or at WCSC if not within first 15 places).

Rating is a numerical value which solver gains by solving in two adequately approved tournaments.

Rating can be gained at the WCSC, PCCC-Open, or other tournaments which fulfil definite criteria.

The rating list is published twice a year. It is calculated on the basis of the results of the solving tournaments completed (including the report) until the end of June and the end of December.

PCCC authorises a person(s) or a commission responsible for calculating the ratings according to the approved formula.

At the tournament at least 10 (15 for gaining norms) solvers with ratings from at least 3 countries should compete.

The selected compositions should be originals or alternatively unknown published compositions. The selected compositions should show a clear theme and a good level of quality and difficulty and should represent different styles.

For the tournaments organized according to the WCSC rules, the full coefficient is used to calculate ratings.

For the other tournaments one half of normal coefficient is used to calculate ratings. In those tournaments there should be at least 12 compositions of different types to solve. Compositions for solving can be chosen out of seven groups: twomovers, threemovers, moremovers, endgames, helpmates, selfmates and fairy compositions. At the tournament there must be represented at least 5 groups with at least 2 compositions. No group can be represented with more than 3 compositions. All compositions are valued with the same number of points. The tournament could be divided into more rounds and/or days.

All tournament documentation (compositions with solutions, complete list with the results and ratings, judge's statement on the competition regularity and possible complaints, etc) should be sent to the responsible PCCC representative (commission) within 30 days after the end of the competition. The representative (commission) has the right to confirm or not the regularity of the tournament. The final decision is approved by the PCCC.

1. For rating calculation the results from all WCSC are included since 1986, inclusive. For the first four rated WCSC (1986-1989) the performance rating is calculated according to the mean point gain of the best 12 solvers that corresponds to 2600 points. The performance ratings are calculated applying direct proportion. The rating from the first four WCSC is calculated as a mean point gain. In case disqualified compsitions appear during the competition the performance rating is calculated with a corresponding coefficient k.

Example:

              86         87       88       89
H.Axt   (843,99x0,94 + 933,89 + 733,33 + 513,32) = 754,79 + 1600 = 2354,79

3. At the competitions since 1990 the mean point gain and the mean rating of the attended enlisted solvers is calculated. On this basis the expected results of the solvers with rating is calculated by direct proportion. The expected result cannot exceed the 100% result. The rating rise or fall is the difference between the real and expected result multiplied by a coefficient 4. In case disqualified compositions appear during the competition the coefficient 4 is multiplied by a coefficient k.

Example:

             Bonn 92  mean point gain:     1665: 33 =  50,45
             mean rating:              27080,89: 33 = 820,63
