Entries: Entries must be received by Sunday 27 August. Late entries will be at the discretion of the arbiter and may not be included in the first round draw. CLICK HERE TO ENTER. Right of entry is reserved.

Draws: The draw for the next round will be circulated by email and published on the webpage on the Sunday night before the round is scheduled to be played.

Norths Chess Club tries to have as many players as possible have an opponent in every round. Players can be left without an opponent by forfeit. Where the organisers have been advised in advance of a player needing to forfeit (for example due to illness) a new set of pairings may be issued. We recognise this may advantage or disadvantage a player and will attempt to minimise this. New pairings will be made following advice given no later than the day before play and will be published by email and website on the evening before play.

Half-point Byes: Up to two half-point byes are permitted in rounds 1-7. Requests for a bye must be received by the arbiter no later than midday on the Sunday immediately prior to the round.

Forfeits: Any player who arrives at the chessboard more than one hour after the scheduled start of the session shall lose the game, unless the Arbiter decides otherwise.

If you won't make it to a round, you must inform the organisers. Your opponents make an effort to come to the club expecting to play a game, some travelling a long way and by public transport. Making them wait for you to not arrive is impolite and against our club ethos.  The club email is monitored up to the start of play. 

Players who cause clock forfeits will be excluded from the following round. Players doing so twice in a tournament will be removed from the remaining rounds and entry to other events may be refused.

Recording of Moves: All moves must be recorded on the provided score sheet.

Electronic devices: Without the permission of the arbiter a player is forbidden to have a mobile phone or other electronic means of communication in the playing venue unless they are completely switched off. If any such device produces a sound, the player shall lose the game. The arbiter must be asked for permission before the start of play if a device is needed for health or emergency reasons.
