The rules of play for blind and partially sighted players are identical to the ordinary ones. What differs is the equipment and the way move information is exchanged. That matters for an organizer: adaptation is a question of equipment and logistics, not of a separate competition system.
International coordination in chess for the blind is handled by the IBCA, which runs its own competitions, and the FIDE laws contain a separate appendix for players with a visual impairment.
The practical consequence: a mixed event with both blind and sighted players is possible and happens regularly. It only needs preparing in advance.
This equipment is produced commercially and held by chess federations and organizations for the blind. For a one-off event it is usually hired or borrowed from such an organization rather than bought.
The key difference is that moves are spoken. A player announces their move aloud and the opponent repeats it on their own board. Algebraic notation is used, with square names pronounced in full for clarity.
Touching a piece on one's own board does not trigger touch-move: feeling the position is a necessary part of the game for a blind player. The move counts as made when the piece is placed on its new square and announced.
The score is kept in Braille, on a recorder or by an assistant. Where several players need one, a single assistant can cover several tables - that is normal practice.
Here the adaptation does not touch the game at all - only the venue. What to check in advance:
If moving the pieces is difficult, an assistant may make the moves as directed by the player. The arbiter decides on that arrangement, and it is better agreed before the event than in round one - arbiting.
Chess is a visual game, so the adaptation is minimal. Two things matter: all key information must be duplicated in writing rather than only announced, and the start of a round must be visible.
An app helps a great deal here: pairings, tables and colours are visible on every phone, so hearing an announcement is not required at all. In Vibe Chess a player gets their table, colour and opponent as soon as the round is paired, and results are confirmed with a button rather than a conversation.
Where to find players and partners: national and regional associations for blind sport, disability organizations and rehabilitation centres. They usually hold the adapted equipment too.
No. The rules of play are exactly the same; what differs is the equipment and the exchange of moves - moves are announced aloud and repeated by the opponent on their own board.
A pegged board with pieces that fix into it, raised dark squares so the colour can be felt, markers on the pieces of one colour, and a specially designed clock that reports the time. Each player may have their own board.
Touching pieces on one's own board is not a move for a blind player: feeling the position is a necessary part of playing. The move counts as made when the piece is placed and announced.
An accessible venue: step-free entry, a lift where required, an accessible toilet, tables a chair fits under and gangways of at least a metre. The game itself needs no adaptation.
Yes, and it is normal practice. Ask about required adaptations on the entry form, prepare the equipment, place the tables sensibly and brief the arbiter on the arrangements.
Pairings are computed by bbpPairings, an open-source engine implementing the Dutch system by FIDE rules: score groups, floats on an odd field, colour alternation. Free to use.
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.
The venue - choosing a room and seating. Disputes - arbiting. Other audiences - senior players, beginners.
