Vibe Chess is an over-the-board chess club and a free app for running tournaments. The club holds chess evenings in bars and cafes across cities in Russia, Belarus and Kazakhstan: several short games in an evening, a new opponent after each one, and time to talk between rounds. The app at playvibechess.com/app takes over the tournament side - sign-ups, pairings under the FIDE rules, the table and the final standings. Anybody can create a tournament, not just a club or an arbiter.
An honest list of the limits, so that organizers of rated events are not left with false expectations.
Yes. Creating and running tournaments is free, there are no subscriptions or paid tiers, and no limits on the number of tournaments or players.
No. The app opens from the link playvibechess.com/app in an ordinary browser. It also works inside Telegram, and for guests without Telegram there is a separate browser version where the organizer enters the players by hand.
Pairings are made by bbpPairings, an open-source engine implementing the Dutch system under the FIDE rules: score groups, floats with an odd field, colour alternation, no repeat encounters and no two byes in a row.
Formally no: approval of pairing programs is issued by the FIDE SPP commission, and Vibe Chess has not gone through it. The Dutch rules are followed all the same, and the report exports in TRF, which arbiters' programs accept.
Three: a Swiss-system tournament (the organizer sets the number of rounds), a round-robin tournament (everybody plays everybody, with the number of rounds worked out from the field) and a free meetup - an event with no rounds and no pairings, where you pick your opponent at the board.
Any user of the app. The create-event button is available to everybody; no club or arbiter status is required.
No. The format is built for amateurs: several short games in an evening, a new opponent after each one, and time to talk between rounds.
A full survey of what it does - what the app and the bot can do. A comparison with arbiters' programs - chess tournament software. Step by step for organizers - running a tournament in the app and running one in Telegram. Theory - the Swiss system, the Buchholz score, the TRF format. For companies - chess tournaments at work.
