Tiebreak
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.
Also called: tie-break
Equal scores are common in Swiss events, so organizers publish a list of tiebreaks before play starts. FIDE's tie-break regulations say each event should use an ordered list: rank by the first tiebreak, then apply the next to any group still level, and when the list runs out, draw lots unless the rules say the tie stands.
The regulations sort the methods into types. Some use only the results among the tied players, like the direct encounter. Others use a player's own record, such as number of wins, or the results and ratings of opponents, like Buchholz and the average rating of opponents. The choice matters, because each rewards something different: tough opposition, beating the other leaders, or winning rather than drawing.
Players should read the announcement for the order, because the same final scores can produce different podiums under different lists. Where a place carries a title or a qualification, an over-the-board play-off may be used instead. See Buchholz, Sonneborn-Berger, swiss system and knockout tournament.
Compare it with Rapid playoff. A rapid playoff is a short extra game or mini match, played at a faster time control, that decides the winner after players tie in a tournament or match.
A neighboring idea is Match play. Match play is a format in which two players, or two teams, play a fixed set of games against each other and the side with the better total result wins the match.
It sits close to Seeding. 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.
How "Tiebreak" 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.

Buchholz is a tiebreak that totals the final scores of every opponent a player met, so that between two players on equal points the one who faced stronger opposition ranks higher.
Sonneborn-Berger is a tiebreak that adds, for every game, the opponent's final score multiplied by the points you took from them, so a win over a high finisher counts far more than a win over a low one.
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 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.
In a knockout tournament, entrants are placed into a bracket and each pairing is a match or a short series, so every loss ends a player's event and the survivors meet again until one remains.
