For the manager it is also content: photographs, a results table, announcements in the residents' chat. And a reason to post something other than a discount - «we run a tournament every Thursday».
The best slot is a weekday evening starting at 18:30 or 19:00. Residents are finishing work but have not left yet. Friday is worse - people scatter.
Two hours is the shape: registration from 18:30, five rounds of 5+3 blitz or four rounds of 10+5 rapid, prizes at 21:00. Anything longer on a weekday and people arrive late or leave early.
The other workable option is a lunchtime event: three rounds of 3+2 blitz over the break. It takes 45 minutes, costs nobody their evening and works well where residents do not like to stay late - working out the timings.
Sixteen players fit into a meeting room or lounge of roughly 35-40 m²: eight boards across four tables. The kit is eight sets and clocks - and the clocks can be phones.
Worth preparing: table numbers, a screen for the standings (a coworking space normally has one) and a desk for the organizer - seating and layout, a clock in the browser.
With no equipment at all, the first event can run on phones and boards brought in by residents - the space's chat usually produces three or four sets.
A realistic expectation for a first event is 8 to 12 people. That is fine: a regular format grows from one edition to the next, and the first tournament is really the advertisement for the second - taking registrations.
Swiss system, four or five rounds, 5+3 or 10+5. Nobody is eliminated and opponents are matched by score, which for a mixed-strength room is the only sensible option - choosing a system.
Pairings are easiest in the app: the event is created in a minute, residents sign up from the link in the chat, and each round's pairing arrives on their phone. The organizer neither calculates pairings nor shouts them across the floor - how it works.
Two rules worth announcing: phones on silent, and quiet in the playing area. In a coworking space that matters more than usual - people are working a few metres away.
Adjacent formats for a business audience - office tournaments and chess team building.
For sixteen players, a meeting room or lounge of about 35-40 m²: eight boards across four tables. The general rule of thumb is roughly 2 m² per player plus room for the organizer's desk.
A weekday evening starting at 18:30 or 19:00, running about two hours. Friday is worse because people leave. The alternative is a lunchtime blitz of three rounds, which fits into 45 minutes.
Realistically 8 to 12. A regular format grows edition by edition, so treat the first tournament as the advertisement for the second rather than as a one-off.
Board and piece sets, one per two players. Clocks can be replaced by a free timer on a phone. The first event can genuinely run with no purchases at all, on boards the residents bring in.
Chess is a quiet format - the games are close to silent. Announcing two rules is enough: phones on silent and quiet in the playing area.
Everything people usually keep in a spreadsheet is already in the app: pairings, points, tie-breaks, round order. Free, with no subscriptions and no cap on the number of players.
many players, one evening: four or five rounds are enough
the fairest format for six to ten players
not a tournament, just an evening of chess - who is free and who is playing is visible in the app
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.
