Events
The IJCCRL Events hub is the operational map for active and scheduled chess engine tournaments. It separates Original UCI Track and Derived Stockfish Track activity, points users to live broadcasts, and routes closed material toward Archive, Downloads, Winners, Rating Lists and PGN Games History.
Current cycle
Live routingOriginal UCI Track — Main international track
The Original UCI Track is the primary IJCCRL competition lane for original UCI engines. Active events should route users to the Original UCI live surface and to the corresponding rating pages only when the data is ready for publication.
Derived Stockfish Track — Secondary technical track
The Derived Stockfish Track remains a separate IJCCRL lane for Stockfish-derived engines. It must not be merged into Original UCI results, rating history or winner identity. Its packs, provisional standings and closure material should remain clearly labelled.
Internal routing rule
Do not mix surfacesEvents is the live map
Events should explain what is running, what is scheduled, what track is involved and where the user should go next. It is not the place to paste full game archives or full rating tables.
When an event closes
A closed event should be routed to Winners for champion identity, Archive for historical preservation, Downloads for files, Rating Lists for Elo impact and PGN Games History for aggregate game statistics.
