IECG Rules and Regulations, version 5.1a

(January 12, 2000)

IMPORTANT : Please try to keep your copy of the rules updated! At this moment we have:
  1. Version 4.2 (August 27, 1996)
  2. Version 5 (August 1, 1998)
  3. Version 5.1 (June 27, 1999)
  4. Version 5.1a (January 12, 2000): the latest, i.e., the document you are reading now. Only change: the old IECG Championship rules have been removed because the tournament has been absorbed into the new IECG World Championship. As a consequence the sections of part D have been renumbered.
The latest version is always valid for *all* tournaments and matches, except for those particular rules that are in clear conflict with other particular rules in older versions, and *only* in case the tournament started before the release date of the latest version. Tournament Secretaries will always rule according to the latest version, unless a player explicitly requests a ruling according to older versions by filing a detailed complaint.

                      A IECG AIMS AND MEMBERSHIP
                      --------------------------

IECG - International Email Chess Group - is an "electronically based"
organization, whose aim is to organize, develop and promote the study
and practice of international email chess all over the world.
It supports and promotes close cooperation between chess players
and other organizations with similar goals. All of its activities are
*free* of charge, and its officials work on a volunteer basis.

IECG was founded at the end of 1994 for a small group of players.
The success was so big that at the end of 1995 IECG claimed to
have 3900 members. Suddenly the organization collapsed and the
former officials were unable to solve the troubles. In the middle of
1996 all IECG activities were stopped. Fortunately, one of our
members assumed the responsibility of reorganizing IECG in a more
open way, and soon other proud members shared their efforts.
As result of this a *new* IECG was born with another structure (a more
"horizontal" and "team-like" one). Services were normalized
and membership started to increase again.

Member Rights and Duties:
-------------------------
All chessplayers around the world can request to be accepted as IECG members.
Membership is free of charge and for life (except for suspension,
cancellation or resignation).
Requests need to be submitted to the IECG Registration Office.
After membership approval, the member is able to take part in the full range
of free IECG chess activities.
Members must acknowledge and observe the Rules and Regulations, and adhere to
the decisions of IECG. Acts which violate the IECG Rules and Regulations
can result in the suspension or cancellation of membership by the IECG
Council.

                          ------------------
                           C  RULES OF PLAY
                          ------------------


In the following the words 'he', 'him' and 'his' include 'she' and 'her'.


All play shall be in accordance with The Official Rules of Chess, as
set forth in Laws of chess, as adopted by the 1996 F.I.D.E. Congress
(Yerevan, Armenia). If there is a conflict between those rules and these,
the IECG Rules take precedence.

The Rules of Play cannot cover all possible situations that may arise
during a game, nor can they regulate all administrative questions.
Where cases are not precisely regulated by an Article of the Rules,
it should be possible to reach a correct decision by studying analogous
situations which are discussed in the Rules.
The Rules assume that arbiters have the necessary competence, sound
judgment and absolute objectivity. Too detailed a rule might deprive the
arbiter of his freedom of judgment and thus prevent him from
finding the solution to a problem dictated by fairness, logic and special
factors. IECG appeals to all its members to accept this view.

Rules are subject to changes due to experience with encountering different
problems during tournaments.
At this moment we have:

Version 4.2 (27 aug 96)
Version 5 (01 aug 98; valid for tournaments started after 01 aug 98)
Version 5.1 (27 june 99; the latest)

The latest version is always valid for all tournaments, except for those
particular rules that are in clear conflict with other particular rules
in older versions, and only in case the tournament started before the
release date of the latest version.

Tournament Secretaries will always rule according to the latest version,
unless a player explicitly requests a ruling according to older version
by filing a detailed complaint to the Tournament Secretary.


-----------------------------------------------
 IECG Playing Rules for individual tournaments
-----------------------------------------------


1   Play and control
====================
A   Games shall be played in accordance with the FIDE Laws of Chess where
    applicable.
B   A Tournament Secretary shall be appointed who shall be responsible for
    the conduct of the tournament and the progress of the games.


2   Transmissions
=================
A   Moves shall be numbered and sent in English algebraic notation
    (preferably in PGN format) or mutually agreed notation
    by email messages bearing the name and
    email address of the sender and a continuous record of all moves
    made and the confirmation of the date on which the opponent's latest
    message was sent.
B   The sender shall record on the message the date on which the opponent's
    latest message was received and the anticipated date of the reply.
C   Failing this, reasonable dates shall be assumed by the recipient and
    notified with the reply move.
D   When the anticipated reply date does not agree with the anticipated
    mailing date, this shall be corrected by the recipient and the sender
    informed with the reply move.
E   The time used for the move (see 6D) and accumulated time for the
    game shall also be recorded.
F   The normal accepted time of the email transmission is one day.
    If a longer transmission time is declared, it may be referred to the
    Tournament Secretary for a ruling.


3   Failure to reply
====================
A   A player may not take more then 30 days for one move.
B   A player who wishes to take more than 12 days for a move must send
    a notice to his opponent, with carbon copy to the TS (Tournament
    Secretary). If not, his time is doubled from the 12th day, or from
    the 24th day.
C   Should there be no reply to any move within 14 days, the full details
    shall be repeated with copy to the TS.
D   If no reply is received after a further 14 days, the player shall
    inform the TS immediately and wait for his decision.


4   Moves and continuations
===========================
A   No legal move shall be retracted after mailing - clerical errors are
    binding if they are legal moves.  A correct repetition of the latest
    move is necessary for the sender's reply move to be valid.
B   Illegible or illegal moves shall be referred back to the sender for
    immediate correction but without any obligation to move the piece in
    question.
C   A message mailed without a reply move shall be treated as an
    illegible move.
D   The omission or addition of chess indications (such as: check,
    captures, en passant) is without significance.
E   Proposals of conditional continuations are binding for the player who
    proposed the conditional sequence, not for the other player, until the
    recipient makes a different move from that proposed.
F   Any accepted continuation move shall be correctly repeated with the
    reply.


5   Records and reports
=======================
A   All transmissions from the opponent concerning the game and a record of
    the moves and dates shall be kept until the end of the tournament and
    sent to the Tournament Secretary upon request
B   If a player does not answer inquiries from the Tournament Secretary,
    that player may be deemed to have withdrawn from the tournament.
C   Changes of email address shall be notified to the Tournament Secretary
    and opponents.
D   The Tournament Secretary must be notified immediately of any
    disagreement between competitors about the game.
E   The Tournament Secretary and opponents must be notified immediately
    if any substantial failure of hardware or software occurs.


6   Time allowed and penalties
==============================
A   Each competitor is allowed 40 days for every 10 moves.
B   The time limit may be exceeded once.
C   Time saved shall be carried forward.
D   The time used for each move is the difference in days between the
    date on which the opponent's latest move was received and the
    mailing date of the reply.
E   Exceeding the time limit can neither be prevented nor caused by
    conditional moves. The time of reflection is added at the sender's
    first move in a sequence of conditional moves and at the recipient's
    answering move to the last conditional move accepted.
F   A penalty of five days shall be added to the time of a player who
    sends an illegible or illegal move, or incorrectly repeats the
    opponent's latest move.

7   Time exceeding
==================
A   Claims that the time limit has been exceeded shall be sent to the
    Tournament Secretary with full details at the latest when replying to
    the 10th, 20th, etc. move.
B   At the same time, the opponent shall be informed by an email message
    with copy to the Tournament Secretary.
C   Any protest shall be sent to the Tournament Secretary within 7 days
    of receiving the message, otherwise the claim shall be deemed to be
    conceded.
D   The Tournament Secretary shall inform both players of the decision
    within 10 days after receiving the claim.
    If the Tournament Secretary upholds a first claim, a new count of the
    opponent's time shall begin on the date of the ruling.
    The next time controls for players who made a first time limit violation
    are reduced to 10 moves/20 days for all remaining moves in the game.
E   A competitor who has exceeded the time allowed for the second time
    shall forfeit the game.
F   If the Tournament Secretary dismisses a claim as being unfounded, he
    may rule that no further claim by that player during the current
    period of 40 days for 10 moves shall be accepted.


8   Leave
=========
A   Each player may claim up to a total of 30 days leave per 12 months
    from the tournament startdate.
B   Players taking leave must inform their opponents and the Tournament
    Secretary in advance.
C   If a player answers a move during his leave, the remaining leave
    for that game is canceled and normal time shall be counted.


9   Withdrawals
==============
A   In any case of withdrawal and regardless of the amount of finished games:
    all unfinished games are forfeited and all finished games are changed
    to "forfeit, adjudicated to the result".
    Example: A wins against B, then A withdraws. B's result will be
    1-0 forfeited, adjudicated 0-1. The tournament itself is not affected,
    only the rating of B, since this game was really played.
    A player may ask for adjudication, but there will be no adjudication
    for games with only a few moves, and the position is not decided.
B   The penalties of withdrawals depend on announced or silent withdrawal.
C   In case of announced withdrawal:
    1. if it is the first announced withdrawal:
       a. if  the player is playing in only one tournament: 6
          months for new events.
       b. if the player is playing in more events: 6 months
          counting from the end of his last finished event, after
          explaining to the Arbiter Commission why he wants to
          withdraw from only one event and not from all.
    2. if it is the second announced withdrawal within one
       year after the first announced withdrawal:
       a. the player will be suspended for 12 months
       b. the player will be withdrawn from all tournaments
D   In case of silent withdrawal:
    1. if it is the first silent withdrawal:
       a. the player will be suspended for 12 months
       b. the player will be withdrawn from all tournaments
    2. if it is the second silent withdrawal:
       a. the player will be cancelled for membership
       b. the player will be withdrawn from all tournaments
E   The suspension may be changed by the Arbiter
    Commission on request of the player.


10  Adjudication
================
A   If no result has been agreed by the date set for the close of play,
    both competitors shall submit to the Tournament Secretary within 14
    days a record of the moves played, the position reached and a
    statement claiming either a win or a draw which may be supported
    by analysis.
B   Competitors not wishing to submit analysis forfeit the right to
    appeal.
C   The Tournament Secretary shall notify the adjudicator's decision to
    both competitors indicating whether it is subject to appeal.


11  Adjudication appeals
========================
A   Any appeal against the adjudicator's decision must be mailed to the
    Tournament Secretary within 14 days of receiving the notification,
    whereupon the Tournament Secretary shall obtain a ruling from another
    adjudicator and notify the result to both competitors.
    The ruling is final and no further appeal shall be accepted from
    either player.
B   Additional analysis may be submitted with an appeal.


12  Reporting results
=====================
A   As soon as possible after ending a game, the result and an accurate
    record of the moves played in PGN - Portable Game Notation - format
    shall be mailed to the Tournament Secretary by the winner (or White in a draw).
    The result is officially recorded only after receipt of this report.
    To ensure accurate recordkeeping, the loser (or Black in a draw) is also
    strongly encouraged to report, labeling such confirmation
    "Duplicate Report".
B   If a game report is not acknowledged by the TS within three days,
    the player should send the report again, labeling it "Repeat
    Report."
C   Should no record be received from either player, the result may be
    scored as lost by both.


13  Decisions and appeals
=========================
A   The Tournament Secretary may penalize or disqualify competitors who
    break these rules.
B   Any matter not covered in the rules shall be decided by the Tournament
    Secretary.
C   Any competitor may appeal within 14 days of receiving a decision of the
    Tournament Secretary
    - in connection with withdrawals to the IECG Rules
      Commission, whose ruling shall be final.
    - for all other decisions to the Appeal Instance.
      whose ruling shall be final.


14  Tiebreaks
=======================
To break ties, the following procedure applies:
1.   better Sonneborn-Berger system
2.   better rating performance (initial ratings at the
     start of the tournament)
3.   direct match

The Sonneborn-Berger system is a tie-breck system well known in the
chess world. This is how it works: each "tied" player scores his
"SB points" adding up as follows:

A = 100% of his opponent's points if he won the individual game
B = 50%  of his opponent's points if he draw the individual game
C = 0%   of his opponent's points if he lost the individual game

The "Sonneborn-Berger" value is A+B+C



15. Global timelimits of tournaments.
============================
A.  For Two game Matches there is a time limit of one year.
B.  For Quads, Class and Large tournaments there is a
    time limit of 18 months.
C.  After the time limit is elapsed there will be an
    inquiry of the TS before he will take a decision about
    the open game(s).



16. Netiquette
=======================

A.  No abuse of other players will be tolerated. Members will not abuse
    other IECG players by sending vulgar, foul or insulting messages.
    Abuse of other players on the basis of character, physical
    characteristics, religion, gender, sexual orientation, intelligence
    quotient, or ethnicity is not allowed. Messages and statements meant
    to harass or bully other players are not allowed.

B.  A player may request a "silent" game, whereupon the opponent must
    not include any comments other than those necessary for the
    progress of the game such as "if" moves and draw offers.

        Please click here for the detailed rules.



     2.2 The IECG Championship

        This tournament has been discontinued and absorbed into the IECG World
        Championship. Please see the rules under section 2.1 above.


     2.3 The annual IECG Cup is started with preliminary rounds once a year.

     a. Participation is open to all IECG members, regardless of
        their chess strength.
     b. It consists of 3 stages: preliminary, semifinal and final.
        Due to the large number of participants, from Cup IV (1998) on
        there is also a quarterfinal stage. Except for the Finals, at
        every stage all games still unfinished after 11 months
        are adjudicated.
        Each preliminary stage is started once a year, with
        7, 9 or 11 players groups (depending on participation),
        single round robin.
     c. The first two placed in each preliminary group qualify to
        the semifinal stage. Starting with Cup IV, the first two placed
        in each preliminary group will qualify for the quarterfinal
        stage. Quarterfinal groups are 7, 9 or 11 player groups, single
        round robin. Depending on the size of the groups, the first two
        or three of each quarterfinal qualify for the semifinal stage.
     d. Semifinal groups are 7, 9 or 11 player groups, single round robin,
        where the winner qualifies to the IECG Cup Final A, and the
        second placed to the IECG Cup Final B.
     e. Both finals (A & B) are 7, 9 or 11 player groups, single round
        robin.
     f. Administration of the IECG Cup is responsibility of the IECG
        Cup Manager named by the IECG Council. He can name assistants
        and Tournament Secretaries to better manage the tournament.
     g. The Cup winner and the second placed are directly qualified
        for the next IECG Cup finals.
     h. The winner of the IECG Cup is also qualified for the IECG
        World Championship (see 2.1).
     i. The winner of an IECG Cup Final B, and all the players in an
        IECG Cup Final A, except for the first and second finishers
        (who are qualified for the next IECG Cup final)
        are directly qualified for the next IECG Cup semifinals.
        In principle, any qualification may be used only once.


     2.4 Class Tournaments are played in 7- or 15-player single round groups,
     where each player plays three (or seven) games as White and three (or seven)
     games as Black. Entry in 15-player groups is restricted to those who have
     already completed at least one seven-player tournament or quad.

     a. Groups are formed by tournament class as follows:

            ---rating---
      class M   2200 and higher
      class 1   1800 - 2199
      class 2   1400 - 1799
      class 3   1000 - 1399
      class N     up to 999.

     b. The winner of a class M group is qualified for one IECG
        Semifinal Championship entry, starting with M.014 (see 2.1).
        The second ranked in a 15-player group is also qualified.
     c. The winner of a class 1, 2, 3, N tournament is promoted for
        *one* tournament to the next higher class (this also applies
        to the second ranked in a 15-player group). This right is lost
        if at the time of exercise the player already has reached the
        necessary rating to enter the higher class tournaments.
     Practical examples: a Class 3 player wins a tournament, which earns
     him a ticket to a Class 2 tournament. Suppose that when he
     wishes to use the ticket his rating
     c.1) has dropped to Class N : then he may enter a Class 3 group,
          but not a Class 2.
     c.2) has increased to Class 1: then he may *not* enter a
          Class M, because it is more than one Class above his original
          qualification.
     Any qualification may be used only once.
     d. A player may not enter in more than four groups at the same time.
        Permission to enter more than four groups can be granted in special
        cases to experienced players with a very good record of observing
        the IECG rules, upon request.
     e. New groups are started continuously in batch mode, as soon as enough
        entries are received to assure a good mixing of countries.


     2.5 Quad Tournaments are 4-player double round robin tournaments,
     where each player plays a two game match against each opponent.
     The use of chess playing machines/algorithms in assisting move
     selection is not allowed in Quad tournaments.

     a. Groups are formed by tournament class as follows:

             ---rating---
       class M   2200 and higher
       class 1   1800 - 2199
       class 2   1400 - 1799
       class 3   1000 - 1399
       class N     up to 999.

     b. The winner of a class or quad M group is qualified for one IECG
     Semifinal Championship entry, starting with IECG Class M.014 and
     Quad M.001

     c. The winner of a Quad 1, 2, 3, N is promoted to the next
     higher class for one tournament.
     Practical examples: see 2.4.c above.
     Any qualification may be used only once.

     d. A player may not enter in more than four groups at the same time.

     e. New groups are started continuously as soon as four valid
     entries are received.

     f. Promotions in Class/Quad events: in case of ties for first place,
     the tied players wins the right to enter in 1 (one) tournament in the
     upper class if obtained at least 75% of the available points.


     2.6 Two-game matches: a "mini tournament", where one player
     faces another, playing one game with white pieces and the other
     with black pieces.
     Players in two-game matches may agree to play at a different
     time control, provided such time control is communicated in advance
     to the Tournament Director responsible of Two-Game matches.

     2.7 Friendly matches:
     Members can ask to play at most 2 (two) official IECG 2-games matches
     against a specified member friend at the same time. Such matches will
     only be included in the IECG rating system if the rating difference
     between the players does not exceed 250 points. As soon as such a match
     is over, one can enter another one, but one should never be playing
     more than two such matches at the same time. Victories scored by
     forfeit will not count for the IECG Rating System. Both players need to
     send the corresponding Entry Form to the Match Secretary . Such matches
     will be listed separately for control purposes.


     2.8 Class X, Friends Invitational

     2.8.1 These rules are applicable to annual tournaments with the
     participation of the winners of the respective classes. They are called
     Friends Invitational in order that they should be distinguished from
     official contests, such as the championship of the IECG. The Friends Invitational
     for Class 2 keeps the original name of "Jim Krepp Memorial".

     2.8.2 Types of tournaments, qualifications, promotions

     2.8.2.1 The Friends Invitational is to take place every year, one for every
     class (except for Class M). It might be pplayed in one or several stages,
     depending on the number of players. The size of each group may vary from 7 to
     15 players, the number being decided by the Tournament Director, who is
     responsible for organizing the event.

     2.8.2.2 The following players are automatically qualified:
      a. The winner of each tournament in the respective class (except for class M)
      or, in case of a shared win, all players sharing the first place. If two
      or more players reach the same number of points, the order of preference is
      to be decided only by the Sonneborn-Berger system and mutual results. The rule of
      preference according to the best advancement in rating values shall not be
      applied in this case.

      b. The players who reached the first and the second places in the preceding
      Friends Invitational in the same class.

      c. Each player is only entitled to one start, even if he has won more than
      one tournament during the year. On the other hand he has the right to play
      in several classes at the same time if he has achieved results in accordance
      with points a. and b. above.

     2.8.3 The Director invites the players to enter the event. A player cannot
     by himself request a start. The Director will design the groups taking into
     account the total number of participants and the Tournament Secretary for
     each group. If an invited player chooses not to participate, no sanctions
     will be imposed. If he abandons play after the event has started, the
     ordinary regulations of the IECG will apply.

     2.8.4 Aim of the Friends Invitational:
     In addition to mass events, such as the IECG Cup, which comprise a mixture
     of players at all levels of strength, and the IECG World Championship, which
     favors the best players, it seems appropriate organize an annual contest
     between the winners of the year in all the lower classes.
     Before the finals can be played it may be necessary to organize
     preparatory stages. The aim is to let all winners of an IECG class
     meet. Since the finals may comprise from 7 to 15 players, there will be formed
     x qualifying tournaments of 7 to 15 players in order to select the
     participants of the finals. If for instance there are 35 invited players who
     have confirmed their entries to the event, there could be 5 qualifying
     groups, each consisting of 7 players, from each of which the two first would
     go to the finals.

     2.8.5 The winner of each event gets the right to start *one* tournament
     in the class at *two* levels above the present class. If for instance a player
     wins a Friends Invitational in class 3 he gets the right to enter a tournament
     in class 1. This rule is obviously not applicable in class 1.
     If the final reach 15 players the second dets the right to start in the
     class at one level above the present class.

     2.8.6 Starting and ending dates:
     Invitations will be sent out on February 15 every year. Players should
     confirm their participation by March 15. After that the Tournament
     Director will compose the groups in view of the number of players. Games
     under the preparatory  stages, if any, start April 1 should be finished
     by November 1. Any games not finished will be adjudicated. The finals start
     April 1 to November 15 later and should be finished by July 1 the
     following year. Adjudication will be utilized to terminate any games not
     finished by that date.

     2.8.7 Rating regulations
     The results of the games under the event will be calculated in accordance
     with the IECG Tournament rating rules.

     2.8.8 Transfer of qualifications for the Friends Invitational
     A qualification cannot be transferred to the following year. All
     qualifications must have been gained in the year preceding the start of the
     event.


     2.9 Thematic Tournaments

     2.9.1 The IECG Thematic Events start with preliminary rounds four times a
     year in different openings. The openings are laid down by the IECG
     Thematic Event Director, after consulting the IECG Council. All games
     begin after a set sequence of moves.

     2.9.2 Participation is open to all IECG members, regardless of their
     chess strength. Games are not rated.
     All games are played according to IECG-rules and regulations

     2.9.3 Each tournament consists of three stages: preliminary, semifinal and final,
     depending on the number of entries. Each preliminary is started with 5
     or 7 player groups in which every player plays two games (one with white
     and one with black) against all other players. IECG members can choose
     to participate in one or two preliminary groups.

     2.9.4 The first two placed in a preliminary group of 5 and the first three
     placed in a preliminary group of 7 qualify to the semifinal stage.
     Semifinal groups are 5 or 7 player groups, each player again is playing
     two games against all other players. The winner in a semifinal group of
     5 and the first two placed in a semifinal group of 7 qualify to the final. The
     number of players in the final depends on the number of semifinal groups.
     If there are less then 10 players in the semifinal stage, the semifinal
     stage will be changed into a final with all qualified participants.

     2.9.5 If a player qualifies for the semifinal in two groups only one
     qualification will count.

     2.9.6 Administration of the IECG Thematic Events
     is responsibility of the IECG Thematic Events Director nominated by the
     IECG Council. The TD may nominate assistants and Tournament Secretaries
     to assist.





                       ----------------
                        E RATING RULES
                       ----------------

                         Version 1.7

I. General Principles

1. The IECG Rating Scheme is a numerical scheme, in which
   percentage results can be exchanged into rating differences
   and rating differences  into percentage performance probabi-
   lities. It is mainly based on the ICCF Rating Scheme.

2. The basis of the scheme is the normal probability distribution.

3. The performance probability is calculated by the formula

   P(D) = 1/(1+10^(-D/400))

   where
   P(D) is the performance probability
   D is the difference of the ratings of the two players.

4. The expected rating changes based on the percentage result is
   given by

   D(p) = -400 * log10((1-p)/p)

   where

   D(p) is the expected rating change
   p is the percentage result of the player

   and D(0) = -800 and D(1)= 800


5. The formulas used in I.3 and I.4 are good approximation of the
   tables used by the ICCF.

6. The percentage result is calculated by

    p = (2*W+D)/(2*N)

    where

    p is the percentage result
    W is the number of wins in the rating period
    D is the number of draws in the rating period
    N is the number of finished games in the rating period.

II. Rating Period and Rating Method

1. The Rating Period is 2 months. The first period
   of a year starts on January 1st.

2. The Rating List is published on the first weekend of every second month
   on the IECG Webserver at http://www.iecg.org/ . At the same time
   the representatives from the IECG Tournament Offices receive
   a special version of the rating list.

3. For calculating the ratings, the opponents Tournament Entry Ratings,
   which are valid on the day of the rating run, are used.

4. Ratings are calculated in batches. A batch is made of all
   games of a player finished in the rating period. The batches
   do not necessarily contain all results of a tournament.

5. The Rating List contains the following information:
    a) Position on the list
    b) Position in the players class
    c) Players Membership Number
    d) Players Name
    e) Players Country
    f) Players Rating
    g) Players Tournament Entry Rating (TER)
    h) No of rated games of the player with the new scheme
    i) Players Win-Draw-Loss Statistics

III. Established, Provisional and Starting Ratings, Performance
        Differences of Opponents Ratings.

1. A player has an established rating, if he/she has finished
   at least 15 games, otherwise his/her rating is called
   provisional.

2. New players get a starting rating, established by a method
   explained in section VII.

3. Provisional ratings are not published until at least six
   games are accepted for rating.

4. The Rating Office can publish intermediate ratings on the first
   weekend of the months where no rating is calculated. The published
   Performance is calculated as if the rating period had ended
   on this particular date. However, the tournament entry rating is
   unchanged.

5. The performance is not calculated for the first six games,
   i. e. it is treated as the provisional rating.

6. To determine which Class or Quad Tournament a Player may
   enter or in which IECG Cup Group a player may start, his/her
   Tournament Entry Rating is used. The only exception are
   qualifications according to the corresponding tournament
   rules.

7. The Tournament Entry Rating (TER) is equal to the Established
   Rating in the last published Rating List. For Provisional
   Ratings, the TER is equal to the Starting Rating, unless at
   least 10 games are finished.

8. To keep the influence of largely different ratings small for the
   preliminary (and established) ratings, a rating cut-off is used.
   Anytime the difference is larger than 400 points, the opponents
   rating is treated as being 400 points (one tournament class)
   higher/lower than the players rating.

IV. Calculation, Publishing and Use of the Provisional Rating

1. The Provisional Rating is calculated by

   Rp = Rc + D(p)*F

   where
   Rp    Provisional Rating
   Rc    Average of the opponents tournament entry ratings
   D(p)  Expected rating change based on I.4
   F     A Correction factor given by

         F = -2*p*p+2*p+0.5

2. The provisional rating is published for the first time after
   six games are finished.

3. (deleted)

4. If at least 15 games are finished, the provisional rating
   becomes an established rating. This promotion can take place
   only at the end of a rating period. Any additional games are
   treated as results for the provisional ratings as well.

V. Calculation of Established Ratings

1. For each finished game the rating change is calculated by

   dR = k*(W-We)

   where

   dR    Rating change
   W     True game result (win 1, draw 1/2)
   We    Expected result (calculated following V.2.)
   k     Development coefficient (see V.3.)

2. The expected result We is calculated using I.3. with the
   rating difference of the two opponents. It is called P(D) in
   section I.3.

3. The development coefficient is a stabilisation factor and is
   given by

   k = r*p

   with

   r = 10           if Ro >= 2400
   r = 70-Ro/40     if 2000 < Ro < 2400
   r = 20           if Ro<= 2000
   and

   p = 1            if Pn >=80
   P = 1.4-Pn/200   if 30 < Pn < 80
   P = 1.25         if 15 < Pn <= 30
   P = 1.5          if Pn <= 15

   where

   Ro    is the Rating from the previous rating list
   Pn    is the number of all rated games upto the previous
         rating list.

4. The next rating is calculated by

   Rn = Ro + SUM(dR)

   where

   Rn       new rating of the player
   Ro       old rating of the player
   SUM(dR)  Sum of all rating changes as calculated in V.1.
            for each game.

   This whole paragraph has been taken from the ICCF regulations
   with only minor changes.

VI. Sequence of calculation

1. There is no special calculation sequence required, since
   - all ratings are taken out of the previous list
   - no unrated players exist in the rating list (see VII)

VII. New Players

1. New Players with an established ICCF rating will be treated
   as having an established IECG rating, since the IECG rating
   calculation is derived from the ICCF system.

2. New Players with an established rating from a different
   organization or with a provisional ICCF rating do get this
   rating as his Starting Rating. If required the national
   rating will be converted into an FIDE rating with the
   appropriate conversion rule. No plus or minus points
   relative to the IECG Rating are used. The established rating
   must be based on at least six games.

3. New players without a rating will get a Starting Rating of
   800 or a rating estimated by the tutor. This rating should not
   exceed 1700 points.


VIII. Forfeits, Withdrawals, Inactive Players

1. Forfeits based on arbiter decision (claim on time, etc)
   are rated as normal finished games. This is normally a
   single event with an individual player.

2. Withdrawals from tournaments are generally not rated
   depending on the tournament secretary decision.

3. The remaining players may request an adjudication of the
   game to gain rating points. The adjudication is binding.
   Based on the result of the adjudication the rating is
   updated. However, the game is treated as a win in the
   score tables.

   Note: This regulation can lead to a loss of rating points
   of the remaining player, if the adjudication result is
   not a win, but a draw or even a loss!

4. A player is called inactive, if he/she is not playing a
   game in a rating period.

5. Inactive players are removed from the rating list after
   being inactive for one year. Their rating keeps valid for
   another four years. Then the player is deleted from the
   database.

6. If an inactive player becomes active, his/her rating from
   the database is still used.

IX. Transfer regulations from the Old to the New IECG Rating
    Scheme, Inauguration of the Scheme

1. All IECG games started before June 1st, 1996 have to be
   rated with the old scheme, if they are finished before
   January 1st, 1997.

2. From January 1st, 1997 all ratings are calculated following
   this document.

3. All games started after August 1st, 1996, have to be cal-
   culated following this document.

4. This scheme comes into operation commencing January 1st for
   all games after the reorganization. Games finished before
   this date are treated as being finished afterwards.

5. With the inauguration of this document the following steps
   are taken:
   a) All established IECG ratings based on at least 15 games
      are transferred to the new rating scheme as established
      ratings.
   b) All established IECG ratings based on less than 15 games
      are used as a starting rating. If more than 5 games are finished,
      the opponents average for the provisional rating is calculated
      following IV.1.
   c) All provisional ratings are left unchanged and stay
      provisional until 15 games are finished.
   d) All starting ratings are checked if the players does
      have an ICCF rating. This ICCF rating replaces the
      IECG rating, if it is higher, and is used as an
      established rating.
   e) All players who have won an old Class M tournament (#001 to #013)
      before January 1st, 1997 are rewarded an established rating for
      this extraordinary result.

X. Contacts

1. All results must be sent to the corresponding Tournament
   Secretary.

2. All questions concerning the table should be send to the
   Rating Official.

3. The current Rating Official is Dr Ortwin Paetzold
   (opaetzol@gmx.de).
