The Arbiter's Role: Before, During & After

Guide · Chapter 07 Complete guide to the chess arbiter's role: before, during and after the tournament. Common rulings, Laws of Chess decisions, FIDE arbiter titles explained.

The arbiter is the guardian of the playing hall. While the organizer handles everything outside — venue, prizes, registrations — the arbiter is responsible for everything that happens at the boards. This chapter gives you a complete picture of the role, from the Laws of Chess rulings you'll face most often to the paperwork you need to keep on file.

Arbiter vs organizer: the crucial distinction

In professional events, the arbiter and organizer are always different people — and for good reason. The organizer has a financial and reputational stake in the tournament's outcome. The arbiter must be impartial. Mixing the two roles creates a conflict of interest.

In club and school tournaments, one person often wears both hats out of practical necessity. This is acceptable, but the person must consciously switch between roles: as organizer, they make logistical decisions; as arbiter, they enforce rules impartially, even if doing so inconveniences their own event.

The clearest practical rule: any decision that could affect the result of a game belongs to the arbiter, not the organizer. Announcing the prize structure, choosing the tiebreak system, or rescheduling a round — those are organizer decisions. Ruling on an illegal move, deciding a forfeit, or handling a phone violation — those are arbiter decisions that must not be influenced by organizational considerations.

The arbiter's authority is defined in FIDE Laws of Chess E.01 (effective 1 January 2023), Article 12 — The Role of the Arbiter. → Read E.01

FIDE arbiter titles: FA, IA, and national titles

FIDE grants arbiter titles that certify a person's competence to officiate chess events. These titles are not required for club or school events, but are required — or strongly recommended — for FIDE-rated tournaments.

Title Full name Typical use How to obtain
IA International Arbiter Major international events, Olympiads, world championships Pass FIDE IA seminar + experience requirements
FA FIDE Arbiter National and international rated events, most FIDE tournaments Pass FIDE FA seminar + 3 rated events as deputy arbiter
NA National Arbiter National federation events; may not be sufficient for FIDE-rated Defined by national federation
None Club/school arbiter Unrated club events, school tournaments Good knowledge of Laws of Chess is sufficient
For club organizers

If you want to run FIDE-rated events regularly, it's worth having at least one FA-titled arbiter in your club. The FA seminar is a 2-day course offered by FIDE and national federations several times a year. It covers the Laws of Chess, pairing rules, and practical tournament management.

For unrated club events, any experienced player who knows the rules thoroughly can serve as arbiter — no formal title is needed.

The three phases of arbiter work

Before the tournament
  • Review tournament regulations
  • Verify venue and equipment
  • Check player registrations and FIDE IDs
  • Set and announce forfeit time
  • Confirm tiebreak order is published
  • Brief deputy arbiters on duties
  • Prepare pairing software
  • Set phone policy and announce it
During rounds
  • Start all clocks at round start time
  • Monitor games for rule violations
  • Handle late arrivals and forfeits
  • Rule on illegal moves
  • Address draw claim disputes
  • Enforce phone policy
  • Collect and verify result slips
  • Enter results into pairing software
After the tournament
  • Verify all results are recorded
  • Calculate and publish final standings
  • Resolve any pending appeals
  • Sign and certify the TRF file
  • Archive score sheets (Standard events)
  • Submit arbiter's report if required
  • Return equipment to organizer

Before the tournament: setup and preparation

The arbiter's work begins well before round 1. Arriving on time and prepared prevents most problems from arising in the first place.

Set the forfeit time — and announce it publicly

Under FIDE Laws of Chess Art. 6.7, the default forfeit time is zero minutes: a player who is not present when the arbiter starts the clocks loses by forfeit. However, the Chief Arbiter may set a different forfeit time before the tournament begins — for example, 30 minutes or 50% of the main time. Whatever you decide, it must be written in the tournament regulations and announced before round 1.

For most club events, a forfeit time of 30 minutes (or half the initial clock time for rapid events) is a reasonable balance between enforcing punctuality and accommodating late arrivals due to traffic or practical reasons.

The phone announcement

Before round 1 starts — not during, before — the arbiter must explicitly announce the phone policy. The FIDE default (Art. 11.3b) is zero tolerance: if a phone makes any sound or is found on the player during play, the game is lost. You may apply a softer policy for club events, but the policy must be stated clearly before any game begins.

Equipment inspection

Walk the playing hall before the first round. Verify that every board has pieces of adequate size, clocks are working and set correctly, scoresheets are available at every board (for Standard events), and the board numbering matches the pairing list.

During the rounds: what to watch for

An experienced arbiter is barely visible during a smooth round — players should only notice them when something goes wrong. Walk the playing hall regularly, moving quietly between the boards. Look for:

Clocks not running. Both clocks should always be running (one stopping when the other starts). A stopped clock when it's a player's turn to move means time is being lost incorrectly.

Players writing before moving. Recording a move before making it on the board is not permitted — score sheets are for recording, not planning.

Phones and electronic devices. Even silent phones can cause forfeits under FIDE rules if found on the player. Be consistent in enforcement — selective enforcement leads to disputes.

Spectators interfering. Spectators must not disturb players or communicate with them during play. This includes coaches, parents, and other players whose games have finished.

12 common rulings explained

These are the situations an arbiter faces most often. For each one: the typical scenario, the relevant FIDE law, and the correct response.

📱 Player's phone rings or vibrates during the game
FIDE Law
Art. 11.3b: if a phone makes any sound or is found to have been used, the game is lost for that player. The opponent's result is decided by the arbiter.
→ E.01 Art. 11.3b
Correct response
Approach calmly, stop both clocks, and declare the game lost for the player whose phone sounded. In most cases award a win to the opponent. Do not give a warning first — the law makes no provision for warnings.
Player arrives late
FIDE Law
Art. 6.7: the default forfeit time is zero. A player who is absent when clocks start loses unless the Chief Arbiter has set a different forfeit time before the tournament.
→ E.01 Art. 6.7
Correct response
Apply the forfeit time announced in the regulations. If the player arrives within the forfeit time, they start with the clock already running — time already elapsed is lost. They do not get extra time.
Illegal move made on the board
FIDE Law
Art. 7.5: first illegal move → the position is restored and the opponent receives 2 extra minutes. Second illegal move in the same game → the game is lost for the player who made it (opponent must have sufficient mating material).
→ E.01 Art. 7.5
Correct response
Stop both clocks. Restore the position to before the illegal move. Add 2 minutes to the opponent's clock. Remind the player that a second illegal move will forfeit the game. Note the incident in your records in case there is a second violation.
🤝 Draw claim by threefold repetition
FIDE Law
Art. 9.2: a player may claim a draw if the same position is about to appear for the third time (before making the move) or has appeared three times (after making the move). The player must stop the clock and write the intended move before claiming.
→ E.01 Art. 9.2
Correct response
Ask the player to write down their intended move (without playing it). Stop the clocks. Verify the repetition using the score sheet — the position, not just the moves, must have repeated with the same player to move. If valid, declare a draw. If invalid, add 2 minutes to the opponent's clock and the game continues.
Player claims their opponent's flag has fallen
FIDE Law
Art. 6.10: the arbiter decides. A flag fall (time expiry) is only a loss if the opponent has sufficient mating material. If the opponent has only a king remaining, the game is a draw regardless of clock status.
→ E.01 Art. 6.10
Correct response
Stop both clocks. Confirm the flag has fallen. Check if the opponent has sufficient mating material (at minimum: a pawn, rook, queen, bishop + knight, or two bishops). If yes, declare time forfeit. If the opponent has only a bare king, declare a draw.
🔄 Player touches a piece but claims they didn't mean to move it
FIDE Law
Art. 4.3: if a player touches a piece with the intention of moving it, they must move it (if a legal move exists). The player must clearly state "j'adoube" (or "I adjust") before touching a piece to adjust it.
→ E.01 Art. 4.3
Correct response
If the player touched the piece without saying "j'adoube" first, they must move it. If a legal move is possible with that piece, it must be made. If no legal move is possible with the touched piece, there is no penalty — but keep a watchful eye on that player.
📋 Player stops keeping score (Standard event)
FIDE Law
Art. 8.4: if a player has less than 5 minutes on the clock (in time controls without increment, or without sufficient increment), they may stop recording moves. With an increment of 30 seconds or more, recording is always required.
→ E.01 Art. 8.4
Correct response
Check the time control and the player's remaining time. If the conditions for stopping recording are not met, ask the player to continue recording. If a dispute arises about the position, you may use both players' incomplete score sheets plus the arbiter's own observation to reconstruct the game.
😤 Player behaves disruptively or rudely
FIDE Law
Art. 12.7: the arbiter may expel disturbing persons from the playing venue. Art. 12.6: a player who repeatedly disturbs the round may be warned, penalized with time, or have the game forfeited against them.
→ E.01 Art. 12.6-12.7
Correct response
Approach calmly and quietly. Issue a verbal warning first (unless the behavior is severe). Document the incident. For persistent disruption: time penalty (add time to opponent's clock) or game forfeit. Always stay calm yourself — an agitated arbiter escalates situations.
Players dispute the result of a game
FIDE Law
Art. 8.7: if both score sheets are incomplete or contradictory, the arbiter uses all available evidence to reconstruct the game and determine the result. The arbiter's decision is final subject to appeal.
→ E.01 Art. 8.7
Correct response
Collect both score sheets immediately and stop any discussion between the players. Reconstruct the game from the beginning of the discrepancy using both sheets and witness accounts. Do not accept verbal accounts alone — written evidence always takes priority.
🏳 Player resigns or offers a draw verbally without recording it
FIDE Law
Art. 5.1.2: a player resigns when they stop the clock and indicate it to the arbiter, or when they tip their king. Art. 9.1: a draw offer is valid at any point during the game.
→ E.01 Art. 5.1.2 & 9.1
Correct response
Confirm the result with both players verbally, then ensure the result slip is signed by both. A resignation or draw offer cannot be retracted once accepted. If a player attempts to retract, the original result stands.
🏁 Both players claim the opponent's flag fell first
FIDE Law
Art. 6.10.1: if the arbiter cannot determine which flag fell first, the game shall continue. Analog clocks rarely allow precise determination; digital clocks with flag indicators make this clearer.
→ E.01 Art. 6.10.1
Correct response
If using digital clocks: check the display — most digital clocks indicate which flag fell. If using analog clocks or if uncertain: restart both clocks with the time remaining at the point of the claim. If truly impossible to determine: continue the game. Never guess.
Player claims insufficient mating material (dead position)
FIDE Law
Art. 5.2.2: the game is drawn when a position arises from which checkmate cannot occur by any sequence of legal moves, even with the most unskilled play. This is automatic — neither player needs to claim it.
→ E.01 Art. 5.2.2
Correct response
Verify the position on the board. Classic dead positions: KK, KBK, KNK (lone king vs king + minor piece). If checkmate is genuinely impossible by any sequence of moves, declare a draw immediately regardless of what the clocks show.

After the tournament: results and reports

Once the final game concludes, the arbiter's role shifts from enforcement to documentation. This phase is often rushed — but getting it right matters for rating submissions and dispute resolution later.

Verify every result. Compare the final standings in ChessPairings.org against the signed result slips. Discrepancies are easier to correct now than after the TRF has been submitted to the federation.

Resolve any pending decisions. If any ruling was deferred or is under appeal, it must be resolved before the TRF is exported. An unresolved result means the standings are provisional and cannot be submitted.

Sign the TRF. The arbiter's signature (or digital certification) on the TRF certifies that the tournament was conducted according to the rules. Some federations require the arbiter's FIDE ID in the TRF header.

Documentation the arbiter must keep

For FIDE-rated Standard events, the arbiter must retain the following for at least one year after the tournament (or per federation requirements):

Signed result slips from every game — these are the primary evidence in case of disputes. If result slips were not used (some rapid events), signed score sheets serve the same purpose.

Pairing lists for every round, showing board numbers, player assignments, and colors. Print and retain a signed copy — a screenshot of the software is not sufficient for official records.

Incident log. Any ruling, warning, or penalty issued during the tournament should be recorded in writing at the time it occurs, including the time, board number, the nature of the incident, and the decision taken.

The appeals process

Every tournament should have an appeals procedure announced before round 1. In club events, this is often simplified: a player may appeal a decision to a designated appeal committee (typically 3 people not involved in the game) within a set time after the ruling.

For FIDE-rated events, the standard procedure under FIDE C.11 applies: appeals must be lodged within a specific time window (usually before the next round starts), accompanied by an appeal fee that is forfeited if the appeal is rejected.

The arbiter cannot serve on the appeals committee for their own rulings. If there is no appeals committee, the arbiter's decision is final — which is another reason to appoint at least two arbiters for larger events.

When the arbiter and organizer are the same person

If you're running a small club event alone, here are practical strategies to manage both roles without compromising either:

Write everything down before round 1. The tournament regulations, tiebreak order, phone policy, and forfeit time should all be on paper and signed by you before the event starts. This prevents the "I changed my mind" problem mid-tournament.

Use software to remove human error from pairings. ChessPairings.org generates pairings automatically according to FIDE rules. If a player questions a pairing, you can point to the algorithm rather than a personal decision.

Appoint a deputy for disputes involving your own interests. If a dispute arises that could affect the standings in a way that benefits someone you know personally — or the organizer side of your work — step aside and let a neutral third party decide.
