Chiron 2 x64 - Gauntlet Matches, 100 Rounds

Chiron 2 x64 is a UCI chess engine by Ubaldo Andrea Farina.

Chiron scored 24.88% with 307 wins, 1312 losses and 381 draws against the top 20 chess engines selection the 100 rounds gauntlet matches.

Unfortunately, Chiron's performance was very erratic posting 12.8% or a total of 261 games lost by time forfeit. The effect was the unusual ranking of the strong engines where Strelka 5.7 became number one in the tournament result. The time forfeit percentage is way beyond the tolerance of 5% in this rating list website. Therefore, the Chiron 2 x64 gauntlet matches will not count in the rating list and will wait for a more stable version that maybe released. The rightmost column highlighted with orange color in the table below represents the number of games lost by Chiron in time forfeit.
