Equal Score Does Not Automatically Mean Equal Rank
A tournament can leave participants tied, rank them using an announced ordered list of off-the-board criteria, or use over-the-board play-offs for selected places. The event regulations should establish the method before the competition begins.
FIDE's current Play-Off and Tie-Break Regulations have applied from 1 March 2026. They formalize both the ordering of criteria and the treatment of issues such as unplayed rounds. A label such as “Buchholz” is not enough if a modifier such as Cut-1 is actually being used.
A tie in score can be left shared, resolved by over-the-board play-offs or ranked using an announced ordered list of off-the-board tie-breaks.
Core rule A tie-break is not part of the player's game score. It is a secondary ranking mechanism whose exact definition and order must be known before the event.
Scores & Ties
Game Points
Game points are the points awarded for individual game results or other event-defined game scoring.
Win / Draw / Loss Scoring
The conventional individual game scoring is win = 1, draw = ½, loss = 0 unless event regulations specify an alternative system.
Alternative Scoring by Event
Events may define alternative scoring or team match points; standings must use the announced system rather than assuming 1/½/0 answers every ranking question.
Ways to Resolve a Tie
Shared Place
A shared place leaves tied participants at the same rank/placing where event regulations permit.
Ranked Tie
A ranked tie orders participants who have equal primary score using the announced tie-resolution method.
Over-the-Board Play-Off
An over-the-board play-off resolves a tie through additional games under announced play-off rules.
Off-the-Board Tie-Break
An off-the-board tie-break uses predeclared statistical/result criteria instead of additional games.
Announced Ordered List
Current FIDE tie-break regulations require an ordered list of tie-breaks when this method is used; event regulations should announce the list.
Apply Next Criterion to Remaining Subgroup
When a criterion resolves only part of a tied group, later criteria apply to the remaining tied subgroup according to the current tie-break procedure.
Drawing of Lots After Exhaustion Where Applicable
Drawing of lots can be a final event-specific resolution only where the regulations provide for it after the applicable criteria/play-offs are exhausted.
Common Tie-Break Families
Buchholz
Buchholz (BH) is the sum of the final scores of a participant's opponents under the current tie-break definitions/adjustments.
Buchholz Cut
A Buchholz cut modifier removes specified least-significant contribution(s) according to the current regulation; Buchholz Cut must state the exact modifier such as Cut-1.
Sonneborn-Berger
Sonneborn-Berger (SB) is calculated from opponents' final scores weighted by the score achieved against them under the current definition.
Direct Encounter
Direct Encounter (DE) uses results among tied participants subject to the current completeness/subgroup rules.
Number of Wins
Number-of-wins tie-breaks count wins according to the exact current definition; variants such as wins with Black are separate criteria.
Opponent-Rating / Performance Measures
Ratings/performance-based tie-breaks require clear definitions and can be inappropriate when unrated players are present unless handling is specified.
Progressive / Cumulative — Reference
Progressive/cumulative scores remain an available reference tie-break in current FIDE regulations, but events must announce if/how it is used.
Teams & Unplayed Rounds
Team Tie-Break Variants
Team tie-breaks include team-specific forms such as Match Points vs Game Points, Extended Sonneborn-Berger and Extended Direct Encounter under the current regulation.
Unplayed-Round Adjustments
Unplayed rounds receive explicit current adjustments for Buchholz/SB and related modifiers; do not use an undocumented local shortcut.
Play-Off Design
Who Qualifies
Play-off regulations must specify which tied positions qualify and whether preliminary tie-breaks are applied before admission.
Format
The play-off format—round robin, knockout, match or another approved event structure—must be defined.
Pairing / Seed
Pairing/seeding for play-offs must be stated.
Colours
Colour allocation for play-offs must be stated.
Time Controls
Play-off time controls must be stated.
Breaks / Schedule
Breaks/schedule between play-off games should be specified when relevant.
Further Tie Resolution
Further tie resolution after a still-tied play-off must be defined in advance rather than improvised after results are known.
Practice
Tie-Break Practice
Tie-break practice should recalculate a standings tie using the event's exact ordered list and current unplayed-round treatment.
Tie-Breaks Are Functions of Tournament Data
Two players with the same score can receive different tie-break values because their opponents, results against those opponents and unplayed rounds differ. This makes tie-breaks derived data, not extra chess points earned during the games.
When checking a result, never calculate “Buchholz from memory.” Record the exact criterion name and modifier, the tournament's scoring system, opponent final scores, unplayed-round treatment and the ordered tie-break list. If a criterion breaks only part of a group, continue with the remaining subgroup according to the current procedure.
Buchholz, Sonneborn-Berger and Direct Encounter Answer Different Questions
Buchholz measures the final scores of your opponents and is therefore primarily an opposition-strength measure. Sonneborn-Berger weights opponent scores by the points you actually scored against those opponents. Direct Encounter looks at games among the tied participants when its applicability conditions are met. None of these is “the fairest tie-break” in every event; they encode different ideas.
Modifiers matter as much as the base name. BH-C1 is not identical to unmodified Buchholz, and current regulations define explicit handling for unplayed rounds. When publishing standings, expose the exact criterion rather than displaying a generic “Buchholz” label for several different calculations.
Play-Offs Are Competition Design, Not a Last-Minute Fix
If a title or qualification place will be decided by play-off, the event regulations should already define who enters, the format, colour allocation, time controls, breaks and what happens if the play-off remains tied. A play-off created after the tie exists can change incentives retroactively and should not be assumed to be permitted.
