Swiss system
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.
Also called: Swiss tournament
Picture 120 players in one open. A round robin would need 119 rounds, and a knockout would send most of them home after a single loss. The Swiss system sits between the two: the organizer fixes the round count before play, far fewer rounds than players, and everyone plays every round.
Round one is paired by rating or seed. After that the pairing program groups players by score and pairs within each group, so someone on two points out of three meets another player on two out of three. FIDE's Basic Rules for Swiss Systems add the guard rails. No two players meet twice. With an odd field, one player gets a pairing-allocated bye, with no opponent and a win's points unless the event says otherwise, and nobody gets it twice. Colors stay balanced, so the count of Black and White games should not differ by more than two and nobody gets the same color three rounds in a row, with limited exceptions in each pairing method.
Several pairing methods are approved, among them the Dutch system. The General Handling Rules require them to be objective and reproducible, so different approved programs must reach identical pairings from the same results, and arbiters may not adjust a pairing to favor anyone.
The final order is points first, then tiebreaks such as Buchholz. Since a poor start does not remove you, the format suits big fields of mixed strength. Compare round robin, pairing, bye and tiebreak.
A neighboring idea is 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.
It sits close to Scholastic tournament. A scholastic tournament is an event for school-age players, usually organized in sections by grade or age, with prizes for individual students and often for school teams as well.
Compare it with Sectional. A sectional is a tournament section limited to players inside a set rating range, so that each competitor mostly faces opponents of similar strength and prizes are fought for fairly.
How "Swiss system" applies to your own results depends on where you stand now, and the improvement plans by rating band show what players near your rating work on.

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.
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 tiebreak is a rule that ranks players who finish on the same score, either by a calculation from the results or by extra games, so that the final standings can be published.
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.
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.
