N.B. 1. In all statements, "he", "his", and "him" include "she" and "her".

        2. The Tournament Director may appoint and designate assistants for each Section who

            will make decisions for that section; their decisions will be accepted as if made in person by the Tournament Director, and may be appealed in the usual way (see rule 26).


       1.Any student registered in an Ontario school (elementary or secondary) who is under the age of 21 may play in the Ontario High School Chess Championship.


       2. Teams will be comprised of the three players in one section from the same school with the highest scores or in the case of the Combined Team, one player from each section - Beginner, Intermediate, and Championship. The highest scores will be used for schools with multiple entries in any section.

Sections and Ratings

        3.(a)The system of regular Chess Federation of Canada (CFC) ratings is the primary system used for pairings for the Championship. It is the official, national chess rating system.

The CFC also maintains a Quick-play ["Active"] rating system. For 2012, we shall not use these ratings.

The Chess 'n Math Association (CMA) also maintains a rating system. We shall use CMA ratings as described below. Based on the 2012 situation, we shall use an additive of 200 to adjust CMA ratings to an approximate CFC equivalent.

          (b)The OHSCC will be rated by both the CFC (regular ratings) and by CMA.

          (c)Rating limits by section are:

    Championship: > 1500 ;

    Intermediate: =1500 ;

    Beginner ≤ 1100 AND with less than 2 years' tournament experience.

          (d)The player's rating on which section placement is determined will be as follows:

If a player has an established CFC regular rating (based on 25 or more games),

    that rating will stand.

If a player has a provisional CFC regular rating (based on fewer than 25 games), or is unrated CFC, then placement will be based on the player's CMA rating.

If the CMA rating is established (based on 9+ tournaments),

then the CMA + 200 will stand.

If both ratings are provisional, the CFC rating will stand.

If a player is unrated in both systems, then the player may choose the most appropriate section.

However, if the school has a team, in a league where games are not rated, we ask that such players who have played on the school team for more than 2 years not enter the Beginner section.

We consider league play, using clocks, recording moves, to be equivalent to tournament play.

We wish to restrict the Beginner section to true beginners, who have less than 2 years' tournament experience.

           (e)Players with a lower rating or unrated may play in the Championship section (for example: to complete their team).


           (f)The Beginner Section is organised for players with less than two years' experience and who have no CFC or Chess'n Math ratings or whose rating is not over 1100 CFC.

It is expected that these players know the rules for playing chess including rules for castling and en passant (pawn capture by a passed pawn). This system depends on the integrity of all teacher/coaches: all are asked to see that each of their players plays in the most appropriate section so that all players have a chance to compete fairly.

Registration and Changes

         4,(a)The entry fee shall be $50 per individual player / $40 per player in a school or family group of 3 or more. For the 2012 tournament, the deadline for registration at this rate will be April 30, 2012.

           (b)The entry fee shall be $75 per player with no group reduction from May 1 through May 18, 2012.

           (c)The deadline for players requesting accommodation shall be April 30, 2012.

                 (d) A $20 fee per change in registration or change in accommodation will be applied after May 4, 2012.

                   (e)NO REGISTRATIONS WILL BE ACCEPTED AFTER May 18, 2012.

Equipment; Duration of the Game - Time Controls

        5. Numbered paper chess boards will be supplied. As far as possible, sets and clocks will also be supplied, courtesy of the Ontario Chess Association. Players and teams are requested to provide chess clocks and chess pieces for practice games. Some players may be requested to bring their equipment for the tournament in cases where the provided equipment is not sufficient. Books and equipment will be on sale at the site before the opening of the tournament.

            6.(a)The Championship Section will use Sudden Death in 120 minutes for Rounds 1 and 2. In Rounds 3,4,5 the time control for the Championship Section will be 40 mov0oes in 90 minutes, followed by Sudden Death in 30 minutes, with 30-second increment added after each move..

                 (b)The Intermediate Section will have Sudden Death in 120 minutes for all rounds.

                   (c)The Beginner Section will have Sudden Death in 90 minutes for all rounds.

                   (d)Players may leave the Tournament Hall after marking the game result on the Pairing Sheet (the list of opponents for each round). Note that, while by custom the winner marks the result, or white in the case of a draw, it is both players' responsibility to ensure that the result is posted.

Recording the Games

       7. Both players shall record the game move by move until one player has not more than five minutes left on his/her clock: then they may both stop recording. A tournament Director or a person delegated by the Tournament Director may continue to record the moves.

An accurate score sheet is required for claiming a draw. (See Rule #15 and 16.)

Note: The 5-minute rule mentioned in Rule 7 does not apply to the first time control [rounds 3,4, and 5 in the Championship Section]. Players must record the moves through the completion of the fortieth move. In the second time-control, when one player's clock reaches 5:00 minutes remaining, the rule noted above applies.

Pairings - Swiss System for Tournaments

       8. (a)A Swiss System chess tournament has no knock-outs or eliminations. Every player competes in every round. The players will usually meet another player with the same score or with the closest score.

           (b)Depending on the numbers of players, Championship players may be paired in with Intermediate section players for Rounds 1 and 2. Players can change sections before Round 3 provided they are not rated too highly for this new section. The scores for these games will count in the section in which they finish the tournament.

           (c) Each player will face a different opponent each round.

           (d) No player will compete against someone from his/her own school.

           (e) Age or grade level is not used to determine pairings except possibly in the last round since there are grade prizes in each section.


       9. (a) All teams are asked to check in by 11:30 am to give the Tournament Director time to finalise the lists and make the pairings for each section. Late entries may be given a - point bye for Round One. The Tournament Director will not pair these players for Round 1 but for remaining rounds they will be paired normally.

           (b) Players may request up to 2 byes for Rounds 1-4 in the Championship section and for Rounds 1-5 in the other sections. At the Tournament Director's discretion, he may award a -point for byes with adequate reasons or he may award a zero point bye if the reasons given are not sufficient. Byes allow a player to continue in the tournament.

           (c) When a section has an uneven number of players, the Tournament Director is forced to give a bye to one player, usually the lowest rated player in the lowest score group. Forced byes are awarded one point.

           (d) Byes are not used for tie-break points.

           (e) If possible, players in different sections with byes assigned as in part (c) may be paired so that they may play a rated game. Such extra games will be reported for rating. Otherwise, as noted, the players both receive 1 bye point for their section.

Prizes and Trophies

      10.(a)Trophies are awarded to the top three individuals and teams in each section, to the top three Combined Teams, and medallions are awarded to the top player in each of grades 7 to 12 in each section.

            (b)The Individual and Team Champion in each section, and the Combined Team Champion will also be awarded the custodianship of the permanent trophy for which they will sign to acknowledge receipt and acceptance of their obligation to return it to the next year's championship. A tie for any of these trophies may be broken, or co-champions may be declared; in the case of co-champions, the teacher/coaches will be expected to make arrangements to share the custodianship of the trophy.


           (c)Trophies will be awarded to the best female player(s) in each section according to the following formula:

2 3 females 1 prize; 4 5 females 2 prizes; 6 or more females 3 prizes.

           (d)Medallions will be awarded to the top player in each grade or combination of grades below grade 7, as numbers warrant.

           (e) All trophies and medallions will be accompanied by a gift certificate which may be redeemed at the Chess'n Math display at the site, or within 6 months following the tournament at the Chess'n Math shop or by post. The amounts of the individual gift certificates will be determined by the Tournament Organising Committee.

Forfeits and Withdrawals

      11. (a) If a player misses a game for which he/she was paired, this is a forfeit. The player who wins a game by forfeit must set up the board, start the absent player's clock, and wait one hour from the start of the round before claiming the win. If the player comes late and before the hour is up, the game will continue. The win by forfeit is scored as one point and tle breaker points will be awarded for forfeits.

           (b) A player who forfeits a game will be withdrawn from the tournament; that is, he/she will not play in the rest of the tournament. If the player who has forfeited and his/her coach give adequate reasons for the player's absence, the TD may allow the player to continue.

           (c) Any inappropriate or illegal behaviour on the tournament site including the residences will result in the forced withdrawal of the student or students involved. Entry fees will not be returned and the school will be contacted to report the problem.

           (d) Complaints of inappropriate or illegal behaviour will be dealt with by the Tournament Organising Committee, consisting of the Tournament Organizer, the Tournament Director, and two or three teachers/coaches.

The Chess Clock

     12. (a) Each player shall handle the clock with the same hand with which he/she handles the pieces. Exception: it is permitted to perform castling with both hands.

           (b) No player is permitted to cover more or less permanently the button of his/her clock.

The Won Game

     13. A game is won by the player:

           (a) who has mated his opponent's king,

           (b) whose opponent declares that he resigns,

           (c) whose opponent's flag falls first at any time before the game is otherwise ended, provided that the player with time remaining has the possibility of a win. The player with time remaining must claim the win himself by immediately stopping both clocks and notifying the Tournament Director, who will validate the claim.

The Drawn Game

     14. The player with white pieces is responsible for notifying the Tournament Director of the possibility of a drawn game. The clocks should be stopped, but the pieces must remain in position and no game score marked on the pairing sheet. (See Rules #15 and 16.)

     15. A game is drawn under the normal rules of chess (stalemate, perpetual check and by agreement of both players provided a game has been contested) and also if

           (a) a player's flag falls when his opponent cannot possibly checkmate.

           (b) player very short on time may request a draw and appeal to the Tournament Director in the case that

(i) the player claiming the draw is very clearly winning or

(ii) the player's opponent is continuing in a dead drawn position.

If the Tournament Director agrees, the game is drawn.

           (c) After a claim as in 15 (b), the arbiter may postpone his decision. In this case, the arbiter may award the opponent of the player making the claim an extra 2 minutes on his clock, and the game shall continue in the presence of the arbiter. Having postponed his decision, the arbiter may subsequently declare the game drawn, even after a flag has fallen.

     16. A game may also be drawn and the claim supported where necessary with an accurate score-sheet:

           (a) if the player demonstrates a perpetual check or a forced repetition. (If this claim is found to be false, his opponent is compensated by having two minutes extra time added)

Note: to claim a draw based on three-fold repetition, the player must make the claim before making the move. Call the TD pause the clock and make the move in the presence of the TD, saying "with this move, I claim a draw by three-fold repetition."

           (b) if his opponent has no practical winning chances (if this claim is found to be false, his opponent is compensated by having two minutes extra time added).

The following situations shall be considered positions without "practical winning chances'' (provided there is no forced way to win):

(i) if the claimant has queen vs queen;

(ii) if the claimant has rook vs rook, or rook vs bishop or rook vs knight;

(iii) if the claimant has bishop (or knight) vs bishop (or knight);

(iv) if the claimant has bishop vs pawn, knight vs pawn, rook vs pawn -provided in all cases there is no forced win for the opponent;

(v) king vs a pawn on the "a" or "h" files and bishop on the wrong diagonal, provided that the king is controlling the promoting square.

(vi) in all cases the claimant could have additional pieces.


     17. If both kings are in check and a player announces that he is correcting the irregularity, then the last move shall be established and the correct position set up. The Tournament Director must be consulted. If this correction is impossible to do with the last played move of one player, then the game shall be proclaimed a draw.


Reporting the Score

     18. (a)The winner must mark the game result on the pairing sheet. In the case of a draw, the player with the white pieces must mark the score.

           (b)It is the responsibility of both players to ensure that the result is posted. Teacher/coaches are asked to assist in this regard.

           (c)If no result is posted by the conclusion of the round, the tournament director may treat the game as a double-forfeit and withdraw both players from the tournament.



The Tournament Director Arbiter

     19. In case of a dispute, either player may pause the clocks while the Tournament Director is summoned.

     20. The Tournament Director shall not handle the clock except in the case of a dispute or when both players ask him to do so.

     21. Spectators and participants in another game are not to speak to the players or otherwise interfere in a game. If a spectator interferes in any way, such as by calling attention to a flagfall or an illegal move, the Tournament Director may cancel the game and rule that a new game be played in its stead at a time control not less than Sudden Death in 60 minutes. The offending party will be expelled from the room.



     22. If a player accidentally displaces one or more pieces, he/she shall replace them on his/her own time. If necessary, the player's opponent may start the player's clock without making a move in order to make sure that the player replaces the displaced pieces on his/her own time.

     23. (a)Play shall be governed by the Chess Federation of Canada Laws of Chess which are not inconsistent with these rules.

           (b)CFC rule 5 F) Rules for play with Blind and Visually Handicapped is adapted when and as needed. For details of allowed accommodations, scroll to rule F) at the link:

     24.When leaving the tournament hall to visit other buildings on the university campus or to

go to a restaurant, players are required to be with a "buddy" at all times.


Electronic Equipment

     25.(a)No electronic devices are to be visible in the tournament hall while players are playing tournament games. On or off, if such a device is seen by the Arbiter, the player will be warned to take it back to his/her room in the residence or to give it to the Arbiter for safe-keeping. Should a player be seen with such a device again, the Arbiter will declare the current game lost, and the player will be withdrawn from the tournament.

          (b) The only exception to this rule is an electronic device designed solely for recording the moves of the game. Such devices may be supplied by Monroi for the Championship section, or provided by the player.


Protests and Appeals Committee

     26. (a) Players may protest any ruling of the Tournament Director provided that they do so before they make their next move.

           (b)After a player has verbally made a protest, the game shall continue.

           (c)The player must then put the protest in writing within half an hour of the completion of the game. The teacher/coach may assist the player in writing the protest.

           (d)An Appeals Committee will be established before the start of the tournament. This committee shall consist of five or more experienced tournament directors or teacher/coaches. Any three members of the Appeals Committee who are not teachers/ coaches of either player in the game shall consider and rule on the protest.

           (e)The decision of the Appeals Committee will be given verbally to both players and to the Tournament Director before the next round of the tournament. A written copy of the decision will be given to both players before the end of the tournament.

            (f)The decision of the Appeals Committee will be final.



     27. (a)Where necessary, to award a prize labelled 1st , 2nd , or 3rd , the following computer-calculated tiebreak systems shall be used:

(i) For two players tied, the score of the players' game with each other, if they played;

(ii) the Cumulative system [sum of the players' scores at the end of each round];

(iii) the Sonneborn system [sum of the products of the player's score in each game times the opponent's final score];

(iv) If all of (I), (ii), and (iii) do not work, the Arbiter shall toss a coin of the Realm, first assigning "heads" to one player.


           (b) For the Championship of any section, if possible, a play-off game may be held.


           ( c) If a play-off game cannot be held, Co-Champions may be declared.
