COMS Chess League

About Us

The COMS Chess League is an active program of the Competitive Operations Management System, an organization founded on June 18, 2019, with the sole purpose of promoting and facilitating organized competition, both online and in person, and through a variety of games.

Since it's establishment, the Chess League has evolved from a simple yearly tournament, who's members were confined to a specific geographic location and a number no greater than 12, to a large scale operation capable of hosting multiple tournaments simultaneously with minimal human coordination, allowing for tournament standings to be calculated and dealt back to players within seconds, and minimizing the potential for human error.

Along with these improvements came the ability, and the willingness of the coordinators to expand the Chess League, allowing practically anyone who meets a small number of conditions to apply for a lifetime membership.

With the changes enabling you to obtain a free membership, you're now allowed to begin participating in our seasons. Sign up here!

Tournament Style

The majority of tournaments hosted by the COMS Chess League use what's known as a round-robin approach during the regular season, followed by a single elimination bracket during the playoffs. This means that everyone plays everyone else exactly once, and those who have won as many or more games than they've lost advances to the playoffs, where they will need to win every game from then on if they're to win the Championship.

More Details

When there is an even number of players, each player will play one player twice, in addition to playing everyone else once. These combinations are chosen at random.

When there is an odd number of players, each player will have one bye, which is a round in which they do not play.

Currently, ties are counted as null, and must be replayed to be counted, however an algorithm is currently being developed that would allow a tie to grant half a point to each player, should that method render more effective.

When a season contains 25 players or more, the regular season is broken up into two or more groups, and each group plays the other players within their group as normal; the playoffs also proceed as normal. When the playoffs are finished for both groups, and there are two Champions, one from each group, those two players must play eachother to determine the end Champion. In a situation where there are an odd number of Champions that must play eachother (currently unprecedented), the two players with the inherent disadvantage (that is, having to play an additional game) will be determined based on their performance during the regular season, or if no determination can me made on those grounds, by playing additional game(s).

Unless specified otherwise, all game rules are in accordance with the U.S. Chess Federation (USCF)
