The IGA League is the Irish Go Association’s primary online tournament, giving IGA members the opportunity to play competitive, rated games throughout the year. We also welcome friends from other associations.
The League operates two seasons each year: Spring (April–June) and Autumn (September–November). Games are played on OGS, and you will play 2–3 games each month. The League Commissioners are Byoung-Ju Lee (blee.dublin) and Eoghan Barry (rottenhat).
The League is divided into Groups of 4–5 players. Each Group plays a double round-robin, meaning that you face each other player in your Group twice in a season, once taking black, once taking white. You receive one point for each win, with a bonus point for winning both halves of your match against a given opponent. Within a Group, players are ranked by points, with ties broken by direct confrontation (the games between the tied players) then by position at the start of the season.
At the end of the season, the player at the top of each Group is promoted to the next Group up, while the player at the bottom of the Group is relegated to the Group below. In some seasons there may be additional promotions and relegations to allow the formation of new Groups.
Results are submitted to the European Go Database for rating — the IGA League is a Class D online tournament for ratings purposes.
Joining the League
Open registration begins approximately six weeks before the start of the season. We will place you in a Group determined by your EGF and OGS ratings — if there is no Group suitable for you, you will have to wait until next season. Except under exceptional circumstances, no one will be placed in the top Group — you must play your way into Group A.
We open new spaces every season so usually we can accommodate everyone who wants to join but we can’t guarantee everyone a spot. Places are allocated on a first come, first served basis.
Entry is free to members of the Irish Go Association. Guests from other Associations pay an entry fee of €5 per season.
