Pairing
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.
Also called: pairings
Pairings are how a tournament turns a list of players into games. In a round robin 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 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, bye, board number and seeding.
It sits close to Bye. 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.

In a Swiss-system tournament the number of rounds is announced in advance, nobody is knocked out, and every round pairs players who have scored about the same so far, never matching the same two players twice.
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.
A board number identifies the table at which a game is played, and in a team match it also names a player's place in the team order, with board one for the first player.
Seeding is the ordering of players before a tournament starts, usually by rating, which decides how pairings are made in the early rounds and who meets whom in a bracket.
A round-robin tournament schedules each participant against every other participant exactly once from a fixed table, so the standings involve no pairing choices and an even field of n players needs n minus 1 rounds.
