This guide explains how we handle tied scores and pairing conflicts to ensure fair competition.
We use the Swiss System for tournament pairings. Key points:
Players continue playing after a loss
Pairings based on scores after each round
Similar-scoring players compete against each other
We use Swiss-Sys Version 9.73 software, following US Chess Federation rules
Pairings are final once posted
Imperfect Pairings: In case of large rating disparities, the TD may allow teammates to play each other
Byes:
Given when there's an odd number of players
Awards a full point
Limited to one per player per tournament
Requested byes earn 0.5 points for the first missed round
If multiple players have the same score, we use these methods in order:
Modified Median: Sum of opponents' scores, excluding highest and lowest
Median: Sum of all opponents' scores
Solkoff: Total scores of all opponents played
Sonneborn-Berger: Used in round-robins; weights victories over stronger players
Cumulative: Running score after each round
Tie breaks determine trophy and award distribution
Tied players receive the same rank, but physical awards use tie break order
Team scores: Sum of top four players' points
Team tie breaks: Same system as individual, using top four players' results
Early loss to a strong opponent, followed by wins, could result in higher tie break scores
For teams with identical scores, cumulative performance of top four players decides
Report any pairing or tie break disputes to Tournament Headquarters immediately. TDs will review using US Chess Federation rules and Swiss-Sys program.
