Playoff Procedures: The following tie-breaks will be used for the purposes of the crosstable and any special prizes or trophies: 1. Direct Encounter (if applicable), 2. Most Blacks, 3. Koya System, 4. Sonneborn-Berger, 5. Won Games. If two or more Players are tied for first, a playoff will be held to determine final standings among all tied players. 

An Armageddon Game is defined as follows: White shall start with 5 minutes and black shall start with 4 minutes. Black shall be declared the winner if the game ends in a draw.

  • Two Players: The tie will be broken with a two-game rapid match (G/10 +2 delay). If the contest is still undecided, the match will be decided by an Armageddon Game.
  • Three or Four Players: If there are three or four Players tied for first, the Players shall contest a rapid round robin (G/10 +2 delay). If no clear winner is produced, the remaining tied players shall contest a blitz (G/3 +2 delay) a) round robin (if three or four players remain tied) or b) 2-game match (if two players remain tied). If the contest is still undecided, the match will be decided by a series of Armageddon Games.
  • More Than Four Players: If more than four players are tied for first place, a combination of math tie-breaks and playoffs will be used to determine the winner. The format if more than four players are tied for first will be determined by the Arbiter and the Saint Louis Chess Club.
