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. --------------------- B IECG STATUTES --------------------- Please click here to access the separate document. ------------------ 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. ------------------- D TOURNAMENT RULES ------------------- 1 These rules apply to multi-player tournaments or matches, including the IECG World Championship, the IECG Championship, the IECG Cup, Class tournaments, Quad tournaments and Two-game matches. If there is a conflict between the Rules of Play and these, the IECG tournament rules take precedence. 2 Tournament types, Promotions Index: 2.1 IECG World Championship 2.2 IECG Championship (discontinued) 2.3 IECG Cup 2.4 Class Tournaments 2.5 Quad Tournaments 2.6 Two Game Matches 2.7 Friendly Matches 2.8 Friends Invitational 2.9 Thematics 2.1 The IECG World Championship 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 18.104.22.168 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. 22.214.171.124 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.

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.
