Chess Engine Nations Cup — National Superfinals Series

goni-K26 · Post by **goni-K26** » Sat May 23, 2026 3:27 pm

♟ CHESS ENGINE NATIONS CUP ♟
— National Superfinals Series —

Overview

Every country has its own chess engine scene. Some have two. Some have ten.
But only one can be the national champion.

This thread collects independent national Superfinals — head-to-head matches between the strongest engines of a single country, to crown its best.

Each Superfinal is fully independent. Countries do not compete against each other.

Eligibility

A country qualifies if it has:
✔ At least 2 active engines rated 2000+ on my personal rating list
✔ Engines with a confirmed country of origin
✔ Publicly available engines only (no private engines)

Rules

[1] Superfinal played for every country with 2+ qualifying engines.
[2] Candidates selected by my personal rating list (1.5M+ game database).
[3] Candidate selection and match format:

[3a] If gap between #1 and #2 ≥ 200 Elo → No superfinal (dominance too large).
[3b] If gap between #2 and #3 > 70 Elo → #1 vs #2 direct Superfinal (no qualifier needed).
[3c] If gap between #2 and #3 ≤ 70 Elo → Round Robin Qualifier (3–6 engines max). Top 2 advance to Superfinal.

[4] Short draws <30 moves (<60 plies) are repeated with the same opening.
[5] Game errors (forfeits, illegal moves) are not counted — game is replayed.

Czech & Slovakia — Champion: ♛ Motor 0.9
⚠ Quanticade 3.0c disqualified — 12 illegal moves confirmed. Motor 0.9.0 declared champion.
_____________________________________________________

While the official scoreboard puts Quanticade 3.0c in first place, reversing the outcomes of the illegal games (which I have replayed) completely overturns the final result. Therefore, the championship title rightfully belongs to Motor 0.9.0.

Below, I have attached a PGN game that contains an illegal move.
