These rules are not finalised, but are still under discussion. The initial draft is by Steve Kroon with reference to point 9 of the old British Tournament Handbook, and some other sources.

General Rules

Adjudication commitee

The Tournament Director will appoint an adjudication committee before the start of the first match. Any disputes will be referred to this committee, whose decision shall be final.

Rules of Go

The rules of Go, as defined by the Nihon Ki-in, and interpreted by the adjudication committee, shall apply.

Chris Welsh I propose that we link to a formal definition of the Japanese rules - I recommend this one [1], which is both a list of the rules and a lengthy commentary, translated by James Davies.

Late arrival

The late arrival period is timed from five minutes after the appointed time for the start of the match, or five minutes after the announcement of the draw for the round in which the match takes place, whichever is later.

If both players are absent for double the main thinking time, a loss shall be recorded for both of them, or the victory shall be awarded randomly if a double-loss is not acceptable to the tournament format.

If both players are late, but one player arrives before the expiry of double the main thinking time, each player will be penalised by the removal of half the time that has elapsed since the start of the late arrival period, and the process will continue as below.

Handicap matches

If white is seated at the table at the appointed time, and black is late, white shall place the handicap stones, start his own clock by pressing black's button, and play his first move. After playing his first move, he shall press his own clock, and wait for black to arrive. If black arrives before the expiry of his main time, he may sit at the table and consider his first move. The game will then continue as normal. If black does not arrive before the expiry of his main thinking time, he will be deemed to have forfeited the game.

If white does not arrive before the expiry of his main thinking time, he will be deemed to have forfeited the game.

Non-handicap matches

If black is seated at the table at the appointed time, and white is late, black shall start his own clock by pressing white's button, and play his first move. After playing his first move, he shall press his own clock, and wait for white to arrive. If white arrives before the expiry of his main time, he may sit at the table and consider his first move. The game will then continue as normal. If white does not arrive before the expiry of his main thinking time, he will be deemed to have forfeited the game.

Time

Chris Welsh Games shall use Canadian byoyomi. Players may pause the clock if capturing more than one stone.

Recording results

It is the duty of the winner of each game to ensure that the result of the game is correctly reported. The Organisers reserve the option of recording a loss for both sides, or awarding victory randomly, if they are not informed of the result.

Komi

Even games shall employ a komi of 6.5 points. Handicap games shall award a komi of 0.5 to White, besides any komi allocated to Black as part of the handicap.

Retraction and completion of moves

A move can not be changed once the player has released the stone on the board. If a move is illegal, the move may be retaken. When clocks are used, a move may only be played once the opponent has completed a move by de-activating his or her clock.

End of game

The game is over after both players have passed consecutively, if a player's time has run out, or if a player resigns.

Both players over time

If both players run out of time, the winner is the first player to notice this.

Chris Welsh I propose that this be changed as follows: If both players run out of time, the result shall be declared jigo. If the tournament format does not support jigo, the winner is the first player to notice this.

Ad hoc rulings

The Tournament Director will decide what action to take under circumstances not covered by these rules.
