Bagatur 5.1c wins New Amateur Chess Engines Test, by CEDR 02-04.09.2024
https://chessengines.blogspot.com/2024/ ... chess.html

As promised, from time to time we will test amateur chess engines. This tournament was won by Bagatur 5.1c and achieved an excellent result winning all games. Second place was taken by the "interesting" CT800 1.46 engine. In 3rd place was the Euwe 1.3.0 engine. The Aramis 1.4.0 engine generates only errors. We checked it on another GUI - it is the same, it seems that it is a bad compilation.

As I promised, we are increasing the number of tests of the most powerful chess engines. In addition, by increasing the number of rounds (6 in this tournament) we want to increase the accuracy of the tests. The tournament was won by Stockfish 20240820 Ivec, which is another example of how good this compilation is. In 2nd place, the HypnoS 220824 engine. Places 3 to 5 with the same number of points, the engines: Raid 3.6 TR, Stockfish 16.1 and SF-PRO 23.08.2024.

Stockfish 16.1 wins Strong Engines Tournament (Tests by Jörn Gronemann, 2024.09.04)
https://chessengines.blogspot.com/2024/ ... gines.html

And another big test tournament of the most powerful chess engines. 30 engines, 1740 games!
The official version of Stockfish 16.1 won. The SF-PRO 23.08.2024 engine had the same number of points, but had worse additional scoring.
Places 3-4 were taken by the JigSaw 5.9 and SF PB 200824 engines.
Dragon 3.3 is far behind Stockfish and its derivatives, and the best engine not based on Stockwish code is the Obsidian 13 engine.
We invite you to follow the site, more tournaments coming soon.
