Almost any failure at a tournament is solved in five minutes if it was thought about beforehand, and wrecks the evening if it was not. And what wrecks it is not the breakage but the pause: twenty people standing for twenty minutes watching a flustered organizer go home feeling the evening failed - even if the tournament was finished afterwards.
What to do in the first minute
Tell the room out loud what happened and how long it will take - even if you do not have the solution yet: «the clock on board three has died, we're swapping it, two minutes». People wait calmly for a known length of time and cannot bear an unknown one.
The second rule: one person decides. A committee of five participants in the middle of the hall takes longer than any repair.
The rule for this whole block: tell people immediately. An event cancelled in the morning is accepted calmly; one cancelled an hour beforehand is remembered for a long time.
The most frequent emergency of all, and in both directions it is a five-minute fix - if you know what to change.
A prepared answer to «what if twice as many turn up» costs ten minutes of thinking at home and saves an evening - choosing a system.
More on conflicts - etiquette and conduct in the hall, appeals.
A separate category: what broke is not the equipment but your own arithmetic. That is harder, because the organizer is at fault - which makes a calm response more important, not less.
The general principle: an error admitted aloud costs almost nothing; one concealed and then discovered by participants costs the evening its reputation.
All of this fits in one bag and covers most failures:
What to carry and how to pack it - transporting equipment, logistics of the evening.
And afterwards: if the disruption was visible, post one short message - what happened and what you will do differently. It costs one message and removes half the impression - about the club chat.
Do not cancel - change the system. With six to ten players a round robin works better than a Swiss and everybody plays everybody. Recalculate the rounds out loud in front of the room so it reads as a decision rather than panic.
The problem is tables, not pairings: two games per table, a shorter time control, and games started in waves if clocks are short. Turn nobody away - somebody who came and did not get a game will not come back.
Swap it for a spare and transfer the times by eye, in favour of whoever had less. Arguing over seconds costs more than being a minute out. Spare batteries and one or two spare clocks belong in the emergency kit.
Withdraw them and score their remaining games as forfeits under your regulations. The important part is recording it before the next pairing is generated, or the pairing will be built around somebody who has gone home.
Briefly and out loud: what happened, what you are doing, how long it will take. Do not apologise twice, do not explain causes in detail, do not ask the room to decide. Name a new time and start exactly then.
Spotted before the games start - redo it and apologise. After they have started - play on, because rearranging games in progress creates more unfairness than it removes. An error in the standings should be corrected openly and immediately.
There are no club or arbiter roles in the app: the create button is available to everyone. You can announce a tournament today and run it this weekend.
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.
For organizers - the checklist, logistics, the team, lateness and forfeits.
