The Chess Engine Nations Cup (CENC) — National Superfinals Series pits the strongest national chess engines against each other in rigorous controlled conditions. Each nation runs a qualifier round-robin to determine the top two engines, which then face off in a 300-round Superfinal to determine the national champion.
All games are played at 9s+0.1s on a single thread. Short draw replays, illegal move handling, and Elo gap rules govern format eligibility.
