Chess Engines Ratings Lists: Official IJCCRL Arena Series 2026 Bullet Results for the Derived Stockfish Track
The IJCCRL Arena Series 2026 — Bullet — Derived Stockfish Track — League Stage is now closed and fully audited. This post records the official Bullet rating outcome of the event, the final league table, the audit status, and the competitive position of the regular-season winner in relation to the rest of the field.
In discussions about chess engines ratings lists, methodological clarity matters as much as the final numbers. A rating list becomes meaningfully interpretable only when its tournament structure, opening policy, side balance, result treatment, and audit doctrine are all stated explicitly. The present IJCCRL league meets that requirement. The event was conducted as an 18-engine Bullet league under a fixed mirrored opening round-robin format with pair ratio 0, and the final record closed at 918 games. Each engine completed 102 games with exact colour symmetry at 51 White and 51 Black games. Ratings were centred on the IJCCRL base of Elo 3700.
Audit conclusion
- Audit verdict: PASS.
- Total games: 918.
- Engines: 18.
- Games per engine: 102.
- Colour balance: 51 White / 51 Black per engine.
- Opening system: fixed mirrored opening round robin, pair ratio 0.
- Two readyok timeout incidents were adjudicated as draws because no clear White advantage was established.
Regular-season winner
Revolution-5.40-190426-sse41popcnt is recorded here as the league winner of the regular season. Revolution finished on 57.5/102, tied on points with Dark SisTer 11, but placed first by the greater number of wins, 49 versus 48. This distinction matters because, in technically grounded chess engines ratings lists, equal scores do not erase structural differences in win production across the same schedule.

What the winner’s profile shows
Revolution’s first-place finish did not come from a runaway lead in points, but from a more productive win profile across the full league schedule. The engine tied Dark SisTer 11 on total points yet secured first place by converting one additional win. Against the field, Revolution’s best score was 4.5/6 versus Deepalienist-4.20-190426-sse41popcnt. It also scored 4.0/6 against Brainlearnjrc-2.10-170426-sse41popcnt, Cortex ZKT 11.11, DON dev-20260223-8cfc79bb, and StockfishJRC-1.80-190426-sse41popcnt. Its most difficult matchups were Brainlearn 31 and Stockfish 18, where it scored 2.5/6 against each.
These details are useful in the context of chess engines ratings lists because they show that the leading engine’s rating is not merely an abstract endpoint. It is supported by a distinct distribution of results across a balanced schedule, and that schedule is itself embedded in an audit framework designed to prevent misinterpretation of raw output.
