                      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 word 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

                         C  NETIQUETTE

a.1  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.

a.2  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.

                           D  RULES OF PLAY

All play shall be in accordance with:

a. The Official Rules of Chess, as set forth in Laws of chess,
   as adopted by the 1996 F.I.D.E. Congress (Yerevan, Armenia)
b. Email Playing rules as adopted by the ICCF Congress in Buenos Aires

If there is a conflict between those rules and these, the IECG Playing 
rules take precedence.

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

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 their members to accept this view.

The following rules are valid for IECG events started after
August 1st, 1998.

 IECG Playing Rules for individual tournaments

    latest message was received and the anticipated date of the reply.
C   Failing this, reasonable dates shall be assumed by the recipient and

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 Director for a ruling.

3   Failure to reply
A   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 TD (Tournament
    Director) once every 12 days. If not, his time is doubled from the 
    12th day, or from the 24th day, etc.
B   Should there be no reply to any move within 14 days, the full

    lost to players who have not informed the TD about the delay.

4   Moves and continuations

    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.

Appendix A: Tiebreaks
To break ties, the following procedure applies:
a) better Sonneborn-Berger system
b) individual game result
c) better rating performance 
(taking the initial ratings at the start of the tournament).

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

Appendix B: Withdrawals: (silent or announced)
In the event of a player withdrawing, the Tournament Director shall
decide whether all games are lost or annulled or the unfinished games
adjudicated. The same rule shall apply in the event of death.

As a guideline:
Silent withdrawal and unaccepted withdrawal should result in the loss
of the unfinished games. Health or business reasons (or death) can be
grounds for an accepted withdrawal. Loss of email connection can be
grounds *only* if the player contacts the Tournament Secretary using
fax or another email account (for example: a friend's email account). 

In the case of accepted withdrawal, the player shall be deleted
(games annulled for cross table) if less than 50% of his games are
finished. Should 50% of the games be finished, then the unfinished
games shall be adjudicated provided they can all be adjudicated (according
to the Tournament Director's criteria).

Games finished before the withdrawal remain valid for rating system 

Unfinished games shall be submitted to the official in charge of
the tournament. Details about the whole adjudication procedure
shall be included in the start list.

Penalties for withdrawals:
1    Announced withdrawal: the player is not allowed to enter IECG
     competitions for up to six months, depending on whether valid reasons
     for the withdrawal are given or not.
2    Silent withdrawal: the player is suspended for two years.
3    Repeated withdrawal (to happen at different times): cancellation of

          January 1st of the year the IC starts
        - The player has been invited by the IECG Council on grounds of 
          extraordinary international achievements

        2.3 Finish of a Tournament

        For the scope of the IC, a player has finished a tournament, if 
        he has finished all his games and if mathematically no other 
        player with less points and unfinished games can get the same or 
        better position in the scoretable.

        2.4 Ties in Class or Quad Tournaments

        2.6 Special Invitations by the IECG Council

        The IECG Council may invite players to play in the IECG 
        Championship. This invitation can also mean an invitation to a 
        higher stage the player already has qualified. The IECG Council 
        should not use these special invitations too often.

        The reason for the invitation and the stage may be one of the 
        - The player has shown extraordinary results either 
          internationally or in IECG
        - The player has won multiple IECG Class or Quad Tournaments
        - The player is owner of a FIDE or ICCF International Title

        - The player has gained a qualification in one of the last two 
          IC Semi-Finals (see 3.2.4)
        - The player has won the last IECG Cup
        - The player has won at least three Class or Quad M tournaments 
          in the preceding year
        - The player has been invited by the IECG Council (see 2.6)

        3.3.3  Size of the Finals

        The final should have a size of 13-15 players. Younger 
        qualification take precedence over older ones.

        3.3.4  Winning the Finals

        The winner of the Finals is called the IECG Champion of the year 
        the tournament started. Ties are broken in the sequence:

        - Sonneborn-Berger System
        - Direct Comparison

        If the situation is still undecided, both players are declared 
        IECG Champion.

        3.3.5  Qualification to the Semi-Finals

        The first three positioned players are qualified for an entry 
        into the IC Semi-Finals. Ties are broken as described in 2.4.

        3.4 The Consolation Finals

        3.4.1  Start and End, Adjudication

        The Consolation Finals start on February 15th of each year. They

        qualified to attend a Consolation Final group (see sections 3.1.5 
        and 3.2.5). The exact group a player qualifies for depends on the 
        position in the Semi-Finals or Preliminaries and the number of 
        attending players. If required the IECG Council may invite 
        further players.

        3.4.3  Number and Size of the Consolation Finals

        The number of the Consolation Finals has to be defined by the TD 
        based on the number of attending players. The number of players 
        in each group should be 9-15. 

        3.4.4  Qualification to the IC Preliminaries

        The winner of a Consolation Final group gains a free entry to the 
        next IC Preliminaries. Ties are broken according to 2.4.

        (end of the rules for the IECG Championship)

     2.4  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
     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
        as per 2.4.g) are directly qualified for the next IECG Cup semifinals.
        In principle, any qualification may be used only once.

     2.5  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.
     a. Groups are formed by tournament class as follows:

      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
     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.

     2.6  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:

       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.

     2.7 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.

     2.8 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.

     2.9 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.

     2.10 Class X, Friends Invitational

     2.10.1 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".

     2.10.2 Types of tournaments, qualifications, promotions 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. 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.

     2.10.3 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.

     2.10.4 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.

     2.10.5 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.

     2.10.6 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.

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

     2.10.8 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


                        F 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))

   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)

   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.4 and I.5 are good approximation of the
   tables used by the ICCF.
6. The percentage result is calculated by  
    p = (2*W+D)/(2*N)
    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 . 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 
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
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 
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  
   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) 
   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 
   r = 10           if Ro >= 2400   
   r = 70-Ro/40     if 2000 < Ro < 2400  
   r = 20           if Ro<= 2000
   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

   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)


   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 
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
