Berger Tournament System

About Berger Tournament System

This standalone application maintains four separate tournament slots. Each slot has its own roster, schedule, results, selected round, tie-break setting, and withdrawal records.

• Pairing numbers follow the order of names in the roster.
• For an odd roster, the unused highest pairing number is a bye. A scheduled rest round awards no points.
• In a double round-robin, the last two rounds of the first cycle are transposed. The second cycle uses the base schedule with colours reversed.
• Sonneborn-Berger uses opponents' scores multiplied by points earned against them. Round-robin forfeits are included.
• Direct Encounter averages repeated encounters with each opponent. It is reapplied to smaller tied groups when appropriate.
• Progressive Score adds the player's cumulative score after each included round.
• The selected tie-break is the only tie-break applied. Remaining ties share a position. Pairing number controls display order within an unresolved tie, not sporting rank.
• Current standings include results through the selected round. Final standings include every round.

Withdrawal handling is an administrative convenience: existing results remain unchanged, while unrecorded games from the specified round receive forfeits. The application does not automatically annul earlier results.
