Every page is also served as markdown at its URL plus .md. A pairing is the assignment of two players to meet in a round, together with the colors each will have. FIDE's handling rules give the process some structure. A pairing is the assignment of two players to meet in a round, together with the colors each will have, and in a Swiss event it is produced fresh after every round. Pairings are how a tournament turns a list of players into games. In a [round robin](https://georgelichess.com/glossary/round-robin.md) they come from a fixed table, so everyone's schedule is known on day one. In a Swiss event the pairing for each round depends on the scores so far. FIDE's handling rules give the process some structure. Before round one, players are ranked, usually by rating, then by title, then alphabetically, and the rank becomes the tournament pairing number. In later rounds players on the same score are matched where possible, with no repeated opponents and colors balanced. Once published, pairings may be changed only in a short list of cases, such as two players who had already met, and a wrongly written result or color must be reported to the chief [arbiter](https://georgelichess.com/glossary/arbiter.md) within a deadline fixed in advance. Arbiters usually do the work with pairing software approved by FIDE, because the rules are meant to give the same answer to any approved program. When you check the board sheet, look at your color as well as your opponent. See [swiss system](https://georgelichess.com/glossary/swiss-system.md), bye, [board number](https://georgelichess.com/glossary/board-number.md) and [seeding](https://georgelichess.com/glossary/seeding.md). Also called: pairings. It sits close to [Bye](https://georgelichess.com/glossary/bye.md). A bye is a round in which a player has no opponent and still receives points; in a Swiss event it goes to one player when the field is odd.
