Bullet Rating List — Official 1026-Game Regular Season — 22/05/2026
This page is the official Bullet rating surface for the II BLITZ IJCCRL LIVE ARENA 2026 — Derived Stockfish Track regular season. The audited dataset is closed at 1026 official games after removing one duplicated Dark SisTer vs Deepalienist game that had no mirrored partner and broke the pair-ratio contract. Ratings are centred on Elo base 3700. The first 16 engines in this table qualify for the next knockout phase, and the Round of 16 pairings below are updated to the current executable releases available for the next phase.
Official Elo Ranking — Clean 1026-Game Set
The rating list is placed first because it is the authority for qualification and seeding. Ratings remain attached to the audited 1026-game identities, while the operational executable column documents the current release selected for the next phase. Stockfish 18 is consolidated under its current SSE4.1/POPCNT executable even when the internal UCI id reports a development/build string.

Official Publication Doctrine
This page publishes the official cleaned regular-season rating list for the Derived Stockfish Track. The deleted duplicate is excluded from the public rating surface because it violates the mirrored-pair contract. The official list uses 1026 games, 345 draws and 681 decisive games; White scored 840.5/1026 (81.92%). The top 16 engines advance to the Round of 16 bracket configured above with the current executable releases selected for the next phase.
