Obsidian 12.0 wins New Amateur Engines Test, by Chess Engines Diary 13-16.04.2024

Obsidian 12.0 won the tournament with a large advantage, this engine is clearly superior to the so-called middle class. The new version of the Arasan 24.2 engine performed poorly. Perhaps the introduced amendment (version 24.2.1) will eliminate the errors.
Alexander 1.1 and Saturn 1.3 new engines in our tests started from the initial ranking of 2400 - hence the large increases in the CEDR ranking.
