Arbiting a chess tournament: duties and disputes

Chess looks like a game with nothing to argue about: the rules are formal and the position is in front of everybody. In practice conflicts arise at almost every tournament - and almost never about the rules themselves, but about what the two players remember happening a minute ago.

The arbiter has three jobs. Procedural: announce the regulations, start rounds on time, check the clocks are running. Judicial: settle disputes so that decisions are predictable and identical for everybody. And atmospheric: ask for quiet at the right moment, and stop a disagreement growing.

Worth understanding: having an arbiter does not make an event strict. The regulations set the strictness. The arbiter only ensures that what was announced actually applies.

Before the event:

• read the regulations for contradictions, especially the order of tie-breaks;
• check the equipment: complete sets, working clocks set to the right control;
• check the entry list and starting numbers, and the ratings if they matter;
• prepare the first-round pairing.

During the event:

• announce the format to the players: rounds, time control, conduct;
• publish the pairings and see that people find their tables;
• start each round and check that every clock is running;
• watch the games without intervening unnecessarily;
• settle disputes and record the decisions;
• collect the results and check they are recorded correctly;
• pair the next round and publish it.

After the event:

• check the final table and the tie-break order;
• announce the results and run the prize-giving with the organizer;
• for a rated event, prepare the report for the federation.

What to say and when - the opening announcement.

At a large competition the work is split between several people, each with a defined role.

• The chief arbiter is responsible for the whole event: compliance with the rules and the regulations, approving the pairings, final decisions on disputes, signing off the results.
• The deputy stands in for them and usually runs part of the hall.
• Floor arbiters watch the games on their assigned tables, record results and call the chief arbiter in difficult cases.
• The secretary keeps the paperwork: round protocols, the table, player cards.
• An appeals committee- several people who hear complaints against the chief arbiter's decisions. Formed at official events.

A rough guide to numbers: one arbiter per 20 to 30 players in the hall. At a twenty-player event one person covering every role is enough.

Arbiter qualifications run in grades, from national categories up to FIDE Arbiter and International Arbiter. For a rated event the arbiter's grade matters, and the requirements depend on the status of the competition - check them with your own federation rather than assuming.

The full laws of chess are set out in the FIDE handbook, but in practice a tournament rests on about ten of them.

• Touch-move.A player who touches their own piece must move it if a legal move exists. Touching an opponent's piece means capturing it if that is legal. To adjust a piece, you must say so first.
• A move is made when the piece is released. Until then the move may be changed to another square with the same piece, if legal.
• The clock is pressed with the same hand that made the move. Hovering a hand over the clock is not allowed.
• Losing on time. The player whose flag falls loses - but only if the opponent has any theoretical way to deliver mate. If not, it is a draw. The fall has to be noticed by a player or the arbiter; the clock does not record a result by itself.
• An illegal move in blitz and rapid: the opponent may claim the win, provided they claim before making their own move. In classical the position is restored and time is added to the opponent.
• Draws. Automatic on stalemate, threefold repetition, the fifty-move rule and insufficient material. By agreement at any time - but the offer is made after your move and before pressing the clock - how draws work.
• Phones. Under FIDE rules a phone that rings loses the game. Amateur events usually limit themselves to asking for silent mode - but announce whichever rule you use.

The rules for players themselves - the rules of chess and setting up the board.

The procedure is always the same: stop the clock, touch nothing, call the arbiter, hear both, decide, announce it aloud. The recurring cases:

«He touched one piece and moved another»

The commonest dispute and the most awkward, because there are usually no witnesses. If the claim cannot be established, play continues from the current position. An arbiter must not guess a side - that creates a precedent other people will use later.

The flag fell and nobody noticed

In blitz and rapid it is the player who claims. If neither noticed and the game continued, the result is whatever the game produces. The arbiter may record the fall themselves if they were watching that game at the time.

A player arrives late

The regulations must say in advance how long a latecomer is waited for. The FIDE default is a forfeit for arriving after the round starts, but amateur events almost always allow a margin - 10 to 15 minutes off the latecomer's own clock. What matters is announcing the rule before the start - late arrivals and forfeits.

A dispute about the recorded result

«We drew, but a win is recorded» is easy to settle if both players confirm the result when submitting it. In the Vibe Chess app that is built in: one player enters the result, the other sees it and can contest it, and with no objection it is accepted automatically. A contested case goes to the organizer, whose decision is final.

Noise and prompting from the side

Spectators may not comment on a game. First offence, a warning; second, removal from the hall. At junior events the prompting almost always comes from parents, which is why they belong in a separate area from the start.

A complaint about the pairing

«Why am I Black again» and «why have you given me a weaker opponent» are standard. If the pairing is computed by software to the FIDE rules the answer is simple: the algorithm decides and nobody edits it by hand. That is exactly why the regulations should state that pairings are computer-generated - it removes the suspicion of bias - where pairings come from.

At an official event a player may appeal the chief arbiter's decision. The usual procedure: a written submission within a limited time after the round, sometimes with a deposit that is returned if the appeal succeeds. The appeals committee decides, and its decision is final - how an appeal works.

At an amateur event there is no appeals committee, and that is fine - but it is worth announcing in advance that the arbiter's decision is final. One sentence in the regulations removes half the future conflicts.

A practical point: explain every contested decision out loud and cite the rule rather than your authority. «In rapid, an illegal move has to be claimed before you reply, and you have already moved, so the game continues» lands very differently from «because I say so».

If the tournament is not rated, no qualified arbiter is required. One person who knows the rules and is willing to make decisions is enough. The minimum:

• announce the regulations before round one - format, control, phones, late arrivals;
• say in advance how ties are broken;
• agree that the host's decision is final;
• pair by software rather than by hand, which removes any question of fairness;
• record results in a way that both players confirm.

The last two are covered by default in the Vibe Chess app: pairings come from an engine implementing the FIDE rules, and a result is accepted only once the opponent has confirmed it. What is left for the organizer is the human part - watching the hall and settling the rare dispute.
