Every board gets a number, and that number is the player's main reference: the pairing says «table 7» and they should find it in seconds.
A practical trick: number a couple of tables more than you need. Walk-ups arrive and you are already ready.
All the Whites on one side of the hall, all the Blacks on the other. That is not aesthetics but practice: the arbiter can read the room at a glance and players do not sit on the wrong side.
The board is oriented by the «white square on the right» rule: each player should have a light square in their bottom-right corner. Worth mentioning at the opening - at amateur events boards get turned the wrong way round regularly, and the game starts from a mirrored position.
Clocks go on the same side of every board, conventionally to Black's right. The uniformity matters: a player moves table every round and should not have to hunt for the button.
How the pieces go out in the first place - setting up the board.
The fewer questions the organizer is asked, the calmer the evening. What helps:
If the event runs in the app, printouts are barely needed: each player sees their table, colour and opponent on their phone the moment the pairing is published. Put one sheet at the door anyway - for whoever arrived without a phone or did not work it out.
A tournament that looks like an event is remembered better than one that looks like a meeting in a conference room. The minimum:
What else to fill the evening with - the organizer's guide.
All of it takes about an hour at a first event and around twenty minutes once the routine is settled. Arrive at least an hour before registration opens - the full list is in the organizer's checklist.
Consecutively, left to right and row by row, on cards large enough to read from the door. Table one goes somewhere visible, since that is where the leaders play. Put the numbers out before the players arrive or round one starts late.
All the Whites on one side of the hall and all the Blacks on the other, so the arbiter can read the room at a glance and nobody sits in the wrong place. Clocks go identically on every board, conventionally to Black's right.
By the «white square on the right» rule: each player should have a light square in their bottom-right corner. At amateur events boards get turned the wrong way regularly, so it is worth mentioning at the opening.
Not essential, but it noticeably reduces the questions aimed at the organizer. A television or monitor is enough: standings between rounds, pairings during them. The alternative is a printed pairing sheet at the door.
A clean background with decent light, a prize area you thought about in advance, and a top table you can walk up to. The prize-giving shots are the main content the tournament produces, so choose the spot beforehand rather than in the moment.
No arbiter skills required. The app takes over the part that usually stops people from running tournaments at all: who plays whom in each round and who finishes first.
The bot is constantly improved based on real tournaments. If you need a feature that isn't there yet, message the developers right inside the bot with the /support command. Many features appeared exactly because organizers asked for them, and useful ideas get added quickly.
Choosing the room - the venue. Equipment - boards and clocks. Running the evening - the opening announcement.
